+## Declare ROS messages, services and actions ##
+################################################
+
+## To declare and build messages, services or actions from within this
+## package, follow these steps:
+## * Let MSG_DEP_SET be the set of packages whose message types you use in
+##   your messages/services/actions (e.g. std_msgs, actionlib_msgs, ...).
+## * In the file package.xml:
+##   * add a build_depend and a run_depend tag for each package in MSG_DEP_SET
+##   * If MSG_DEP_SET isn't empty the following dependencies might have been
+##     pulled in transitively but can be declared for certainty nonetheless:
+##     * add a build_depend tag for "message_generation"
+##     * add a run_depend tag for "message_runtime"
+## * In this file (CMakeLists.txt):
+##   * add "message_generation" and every package in MSG_DEP_SET to
+##     find_package(catkin REQUIRED COMPONENTS ...)
+##   * add "message_runtime" and every package in MSG_DEP_SET to
+##     catkin_package(CATKIN_DEPENDS ...)
+##   * uncomment the add_*_files sections below as needed
+##     and list every .msg/.srv/.action file to be processed
+##   * uncomment the generate_messages entry below
+##   * add every package in MSG_DEP_SET to generate_messages(DEPENDENCIES ...)
+
+## Generate messages in the 'msg' folder
+# add_message_files(
+#   FILES
+#   Message1.msg
+#   Message2.msg
+# )
+
+## Generate services in the 'srv' folder
+# add_service_files(
+#   FILES
+#   Service1.srv
+#   Service2.srv
+# )
+
+## Generate actions in the 'action' folder
+# add_action_files(
+#   FILES
+#   Action1.action
+#   Action2.action
+# )
+
+## Generate added messages and services with any dependencies listed here

+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+			    Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+License is intended to guarantee your freedom to share and change free
+software--to make sure the software is free for all its users.  This
+General Public License applies to most of the Free Software
+Foundation's software and to any other program whose authors commit to
+using it.  (Some other Free Software Foundation software is covered by
+the GNU Library General Public License instead.)  You can apply it to
+your programs, too.
+
+  When we speak of free software, we are referring to freedom, not
+price.  Our General Public Licenses are designed to make sure that you
+have the freedom to distribute copies of free software (and charge for
+this service if you wish), that you receive source code or can get it
+if you want it, that you can change the software or use pieces of it
+in new free programs; and that you know you can do these things.
+
+  To protect your rights, we need to make restrictions that forbid
+anyone to deny you these rights or to ask you to surrender the rights.
+These restrictions translate to certain responsibilities for you if you
+distribute copies of the software, or if you modify it.
+
+  For example, if you distribute copies of such a program, whether
+gratis or for a fee, you must give the recipients all the rights that
+you have.  You must make sure that they, too, receive or can get the
+source code.  And you must show them these terms so they know their
+rights.
+
+  We protect your rights with two steps: (1) copyright the software, and
+(2) offer you this license which gives you legal permission to copy,
+distribute and/or modify the software.
+
+  Also, for each author's protection and ours, we want to make certain
+that everyone understands that there is no warranty for this free
+software.  If the software is modified by someone else and passed on, we
+want its recipients to know that what they have is not the original, so
+that any problems introduced by others will not reflect on the original
+authors' reputations.
+
+  Finally, any free program is threatened constantly by software
+patents.  We wish to avoid the danger that redistributors of a free
+program will individually obtain patent licenses, in effect making the
+program proprietary.  To prevent this, we have made it clear that any
+patent must be licensed for everyone's free use or not licensed at all.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.
+
+		    GNU GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License applies to any program or other work which contains
+a notice placed by the copyright holder saying it may be distributed
+under the terms of this General Public License.  The "Program", below,
+refers to any such program or work, and a "work based on the Program"
+means either the Program or any derivative work under copyright law:
+that is to say, a work containing the Program or a portion of it,
+either verbatim or with modifications and/or translated into another
+language.  (Hereinafter, translation is included without limitation in
+the term "modification".)  Each licensee is addressed as "you".
+
+Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running the Program is not restricted, and the output from the Program
+is covered only if its contents constitute a work based on the
+Program (independent of having been made by running the Program).
+Whether that is true depends on what the Program does.
+
+  1. You may copy and distribute verbatim copies of the Program's
+source code as you receive it, in any medium, provided that you
+conspicuously and appropriately publish on each copy an appropriate
+copyright notice and disclaimer of warranty; keep intact all the
+notices that refer to this License and to the absence of any warranty;
+and give any other recipients of the Program a copy of this License
+along with the Program.
+
+You may charge a fee for the physical act of transferring a copy, and
+you may at your option offer warranty protection in exchange for a fee.
+
+  2. You may modify your copy or copies of the Program or any portion
+of it, thus forming a work based on the Program, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) You must cause the modified files to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    b) You must cause any work that you distribute or publish, that in
+    whole or in part contains or is derived from the Program or any
+    part thereof, to be licensed as a whole at no charge to all third
+    parties under the terms of this License.
+
+    c) If the modified program normally reads commands interactively
+    when run, you must cause it, when started running for such
+    interactive use in the most ordinary way, to print or display an
+    announcement including an appropriate copyright notice and a
+    notice that there is no warranty (or else, saying that you provide
+    a warranty) and that users may redistribute the program under
+    these conditions, and telling the user how to view a copy of this
+    License.  (Exception: if the Program itself is interactive but
+    does not normally print such an announcement, your work based on
+    the Program is not required to print an announcement.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Program,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Program, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Program.
+
+In addition, mere aggregation of another work not based on the Program
+with the Program (or with a work based on the Program) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may copy and distribute the Program (or a work based on it,
+under Section 2) in object code or executable form under the terms of
+Sections 1 and 2 above provided that you also do one of the following:
+
+    a) Accompany it with the complete corresponding machine-readable
+    source code, which must be distributed under the terms of Sections
+    1 and 2 above on a medium customarily used for software interchange; or,
+
+    b) Accompany it with a written offer, valid for at least three
+    years, to give any third party, for a charge no more than your
+    cost of physically performing source distribution, a complete
+    machine-readable copy of the corresponding source code, to be
+    distributed under the terms of Sections 1 and 2 above on a medium
+    customarily used for software interchange; or,
+
+    c) Accompany it with the information you received as to the offer
+    to distribute corresponding source code.  (This alternative is
+    allowed only for noncommercial distribution and only if you
+    received the program in object code or executable form with such
+    an offer, in accord with Subsection b above.)
+
+The source code for a work means the preferred form of the work for
+making modifications to it.  For an executable work, complete source
+code means all the source code for all modules it contains, plus any
+associated interface definition files, plus the scripts used to
+control compilation and installation of the executable.  However, as a
+special exception, the source code distributed need not include
+anything that is normally distributed (in either source or binary
+form) with the major components (compiler, kernel, and so on) of the
+operating system on which the executable runs, unless that component
+itself accompanies the executable.
+
+If distribution of executable or object code is made by offering
+access to copy from a designated place, then offering equivalent
+access to copy the source code from the same place counts as
+distribution of the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  4. You may not copy, modify, sublicense, or distribute the Program
+except as expressly provided under this License.  Any attempt
+otherwise to copy, modify, sublicense or distribute the Program is
+void, and will automatically terminate your rights under this License.
+However, parties who have received copies, or rights, from you under
+this License will not have their licenses terminated so long as such
+parties remain in full compliance.
+
+  5. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Program or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Program (or any work based on the
+Program), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Program or works based on it.
+
+  6. Each time you redistribute the Program (or any work based on the
+Program), the recipient automatically receives a license from the
+original licensor to copy, distribute or modify the Program subject to
+these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties to
+this License.
+
+  7. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Program at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Program by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Program.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system, which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  8. If the distribution and/or use of the Program is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Program under this License
+may add an explicit geographical distribution limitation excluding
+those countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  9. The Free Software Foundation may publish revised and/or new versions
+of the General Public License from time to time.  Such new versions will
+be similar in spirit to the present version, but may differ in detail to
+address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Program
+specifies a version number of this License which applies to it and "any
+later version", you have the option of following the terms and conditions
+either of that version or of any later version published by the Free
+Software Foundation.  If the Program does not specify a version number of
+this License, you may choose any version ever published by the Free Software
+Foundation.
+
+  10. If you wish to incorporate parts of the Program into other free
+programs whose distribution conditions are different, write to the author
+to ask for permission.  For software which is copyrighted by the Free
+Software Foundation, write to the Free Software Foundation; we sometimes
+make exceptions for this.  Our decision will be guided by the two goals
+of preserving the free status of all derivatives of our free software and
+of promoting the sharing and reuse of software generally.
+
+			    NO WARRANTY
+
+  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
+REPAIR OR CORRECTION.
+
+  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
+POSSIBILITY OF SUCH DAMAGES.
+
+		     END OF TERMS AND CONDITIONS
+
+	    How to Apply These Terms to Your New Programs
+
+  If you develop a new program, and you want it to be of the greatest
+possible use to the public, the best way to achieve this is to make it
+free software which everyone can redistribute and change under these terms.
+
+  To do so, attach the following notices to the program.  It is safest
+to attach them to the start of each source file to most effectively
+convey the exclusion of warranty; and each file should have at least
+the "copyright" line and a pointer to where the full notice is found.
+
+    <one line to give the program's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This program is free software; you can redistribute it and/or modify
+    it under the terms of the GNU General Public License as published by
+    the Free Software Foundation; either version 2 of the License, or
+    (at your option) any later version.
+
+    This program is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
+    GNU General Public License for more details.
+
+    You should have received a copy of the GNU General Public License
+    along with this program; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+
+
+Also add information on how to contact you by electronic and paper mail.
+
+If the program is interactive, make it output a short notice like this
+when it starts in an interactive mode:
+
+    Gnomovision version 69, Copyright (C) year  name of author
+    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
+    This is free software, and you are welcome to redistribute it
+    under certain conditions; type `show c' for details.
+
+The hypothetical commands `show w' and `show c' should show the appropriate
+parts of the General Public License.  Of course, the commands you use may
+be called something other than `show w' and `show c'; they could even be
+mouse-clicks or menu items--whatever suits your program.
+
+You should also get your employer (if you work as a programmer) or your
+school, if any, to sign a "copyright disclaimer" for the program, if
+necessary.  Here is a sample; alter the names:

+
+ Copyright (C) 1991, 1999 Free Software Foundation, Inc.
+     59 Temple Place, Suite 330, Boston, MA  02111-1307  USA
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+[This is the first released version of the Lesser GPL.  It also counts
+ as the successor of the GNU Library Public License, version 2, hence
+ the version number 2.1.]
+
+                            Preamble
+
+  The licenses for most software are designed to take away your
+freedom to share and change it.  By contrast, the GNU General Public
+Licenses are intended to guarantee your freedom to share and change
+free software--to make sure the software is free for all its users.
+
+  This license, the Lesser General Public License, applies to some
+specially designated software packages--typically libraries--of the
+Free Software Foundation and other authors who decide to use it.  You
+can use it too, but we suggest you first think carefully about whether
+this license or the ordinary General Public License is the better
+strategy to use in any particular case, based on the explanations
+below.
+
+  When we speak of free software, we are referring to freedom of use,
+not price.  Our General Public Licenses are designed to make sure that
+you have the freedom to distribute copies of free software (and charge
+for this service if you wish); that you receive source code or can get
+it if you want it; that you can change the software and use pieces of
+it in new free programs; and that you are informed that you can do
+these things.
+
+  To protect your rights, we need to make restrictions that forbid
+distributors to deny you these rights or to ask you to surrender these
+rights.  These restrictions translate to certain responsibilities for
+you if you distribute copies of the library or if you modify it.
+
+  For example, if you distribute copies of the library, whether gratis
+or for a fee, you must give the recipients all the rights that we gave
+you.  You must make sure that they, too, receive or can get the source
+code.  If you link other code with the library, you must provide
+complete object files to the recipients, so that they can relink them
+with the library after making changes to the library and recompiling
+it.  And you must show them these terms so they know their rights.
+
+  We protect your rights with a two-step method: (1) we copyright the
+library, and (2) we offer you this license, which gives you legal
+permission to copy, distribute and/or modify the library.
+
+  To protect each distributor, we want to make it very clear that
+there is no warranty for the free library.  Also, if the library is
+modified by someone else and passed on, the recipients should know
+that what they have is not the original version, so that the original
+author's reputation will not be affected by problems that might be
+introduced by others.
+^L
+  Finally, software patents pose a constant threat to the existence of
+any free program.  We wish to make sure that a company cannot
+effectively restrict the users of a free program by obtaining a
+restrictive license from a patent holder.  Therefore, we insist that
+any patent license obtained for a version of the library must be
+consistent with the full freedom of use specified in this license.
+
+  Most GNU software, including some libraries, is covered by the
+ordinary GNU General Public License.  This license, the GNU Lesser
+General Public License, applies to certain designated libraries, and
+is quite different from the ordinary General Public License.  We use
+this license for certain libraries in order to permit linking those
+libraries into non-free programs.
+
+  When a program is linked with a library, whether statically or using
+a shared library, the combination of the two is legally speaking a
+combined work, a derivative of the original library.  The ordinary
+General Public License therefore permits such linking only if the
+entire combination fits its criteria of freedom.  The Lesser General
+Public License permits more lax criteria for linking other code with
+the library.
+
+  We call this license the "Lesser" General Public License because it
+does Less to protect the user's freedom than the ordinary General
+Public License.  It also provides other free software developers Less
+of an advantage over competing non-free programs.  These disadvantages
+are the reason we use the ordinary General Public License for many
+libraries.  However, the Lesser license provides advantages in certain
+special circumstances.
+
+  For example, on rare occasions, there may be a special need to
+encourage the widest possible use of a certain library, so that it
+becomes a de-facto standard.  To achieve this, non-free programs must
+be allowed to use the library.  A more frequent case is that a free
+library does the same job as widely used non-free libraries.  In this
+case, there is little to gain by limiting the free library to free
+software only, so we use the Lesser General Public License.
+
+  In other cases, permission to use a particular library in non-free
+programs enables a greater number of people to use a large body of
+free software.  For example, permission to use the GNU C Library in
+non-free programs enables many more people to use the whole GNU
+operating system, as well as its variant, the GNU/Linux operating
+system.
+
+  Although the Lesser General Public License is Less protective of the
+users' freedom, it does ensure that the user of a program that is
+linked with the Library has the freedom and the wherewithal to run
+that program using a modified version of the Library.
+
+  The precise terms and conditions for copying, distribution and
+modification follow.  Pay close attention to the difference between a
+"work based on the library" and a "work that uses the library".  The
+former contains code derived from the library, whereas the latter must
+be combined with the library in order to run.
+^L
+                  GNU LESSER GENERAL PUBLIC LICENSE
+   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
+
+  0. This License Agreement applies to any software library or other
+program which contains a notice placed by the copyright holder or
+other authorized party saying it may be distributed under the terms of
+this Lesser General Public License (also called "this License").
+Each licensee is addressed as "you".
+
+  A "library" means a collection of software functions and/or data
+prepared so as to be conveniently linked with application programs
+(which use some of those functions and data) to form executables.
+
+  The "Library", below, refers to any such software library or work
+which has been distributed under these terms.  A "work based on the
+Library" means either the Library or any derivative work under
+copyright law: that is to say, a work containing the Library or a
+portion of it, either verbatim or with modifications and/or translated
+straightforwardly into another language.  (Hereinafter, translation is
+included without limitation in the term "modification".)
+
+  "Source code" for a work means the preferred form of the work for
+making modifications to it.  For a library, complete source code means
+all the source code for all modules it contains, plus any associated
+interface definition files, plus the scripts used to control
+compilation and installation of the library.
+
+  Activities other than copying, distribution and modification are not
+covered by this License; they are outside its scope.  The act of
+running a program using the Library is not restricted, and output from
+such a program is covered only if its contents constitute a work based
+on the Library (independent of the use of the Library in a tool for
+writing it).  Whether that is true depends on what the Library does
+and what the program that uses the Library does.
+
+  1. You may copy and distribute verbatim copies of the Library's
+complete source code as you receive it, in any medium, provided that
+you conspicuously and appropriately publish on each copy an
+appropriate copyright notice and disclaimer of warranty; keep intact
+all the notices that refer to this License and to the absence of any
+warranty; and distribute a copy of this License along with the
+Library.
+
+  You may charge a fee for the physical act of transferring a copy,
+and you may at your option offer warranty protection in exchange for a
+fee.
+
+  2. You may modify your copy or copies of the Library or any portion
+of it, thus forming a work based on the Library, and copy and
+distribute such modifications or work under the terms of Section 1
+above, provided that you also meet all of these conditions:
+
+    a) The modified work must itself be a software library.
+
+    b) You must cause the files modified to carry prominent notices
+    stating that you changed the files and the date of any change.
+
+    c) You must cause the whole of the work to be licensed at no
+    charge to all third parties under the terms of this License.
+
+    d) If a facility in the modified Library refers to a function or a
+    table of data to be supplied by an application program that uses
+    the facility, other than as an argument passed when the facility
+    is invoked, then you must make a good faith effort to ensure that,
+    in the event an application does not supply such function or
+    table, the facility still operates, and performs whatever part of
+    its purpose remains meaningful.
+
+    (For example, a function in a library to compute square roots has
+    a purpose that is entirely well-defined independent of the
+    application.  Therefore, Subsection 2d requires that any
+    application-supplied function or table used by this function must
+    be optional: if the application does not supply it, the square
+    root function must still compute square roots.)
+
+These requirements apply to the modified work as a whole.  If
+identifiable sections of that work are not derived from the Library,
+and can be reasonably considered independent and separate works in
+themselves, then this License, and its terms, do not apply to those
+sections when you distribute them as separate works.  But when you
+distribute the same sections as part of a whole which is a work based
+on the Library, the distribution of the whole must be on the terms of
+this License, whose permissions for other licensees extend to the
+entire whole, and thus to each and every part regardless of who wrote
+it.
+
+Thus, it is not the intent of this section to claim rights or contest
+your rights to work written entirely by you; rather, the intent is to
+exercise the right to control the distribution of derivative or
+collective works based on the Library.
+
+In addition, mere aggregation of another work not based on the Library
+with the Library (or with a work based on the Library) on a volume of
+a storage or distribution medium does not bring the other work under
+the scope of this License.
+
+  3. You may opt to apply the terms of the ordinary GNU General Public
+License instead of this License to a given copy of the Library.  To do
+this, you must alter all the notices that refer to this License, so
+that they refer to the ordinary GNU General Public License, version 2,
+instead of to this License.  (If a newer version than version 2 of the
+ordinary GNU General Public License has appeared, then you can specify
+that version instead if you wish.)  Do not make any other change in
+these notices.
+^L
+  Once this change is made in a given copy, it is irreversible for
+that copy, so the ordinary GNU General Public License applies to all
+subsequent copies and derivative works made from that copy.
+
+  This option is useful when you wish to copy part of the code of
+the Library into a program that is not a library.
+
+  4. You may copy and distribute the Library (or a portion or
+derivative of it, under Section 2) in object code or executable form
+under the terms of Sections 1 and 2 above provided that you accompany
+it with the complete corresponding machine-readable source code, which
+must be distributed under the terms of Sections 1 and 2 above on a
+medium customarily used for software interchange.
+
+  If distribution of object code is made by offering access to copy
+from a designated place, then offering equivalent access to copy the
+source code from the same place satisfies the requirement to
+distribute the source code, even though third parties are not
+compelled to copy the source along with the object code.
+
+  5. A program that contains no derivative of any portion of the
+Library, but is designed to work with the Library by being compiled or
+linked with it, is called a "work that uses the Library".  Such a
+work, in isolation, is not a derivative work of the Library, and
+therefore falls outside the scope of this License.
+
+  However, linking a "work that uses the Library" with the Library
+creates an executable that is a derivative of the Library (because it
+contains portions of the Library), rather than a "work that uses the
+library".  The executable is therefore covered by this License.
+Section 6 states terms for distribution of such executables.
+
+  When a "work that uses the Library" uses material from a header file
+that is part of the Library, the object code for the work may be a
+derivative work of the Library even though the source code is not.
+Whether this is true is especially significant if the work can be
+linked without the Library, or if the work is itself a library.  The
+threshold for this to be true is not precisely defined by law.
+
+  If such an object file uses only numerical parameters, data
+structure layouts and accessors, and small macros and small inline
+functions (ten lines or less in length), then the use of the object
+file is unrestricted, regardless of whether it is legally a derivative
+work.  (Executables containing this object code plus portions of the
+Library will still fall under Section 6.)
+
+  Otherwise, if the work is a derivative of the Library, you may
+distribute the object code for the work under the terms of Section 6.
+Any executables containing that work also fall under Section 6,
+whether or not they are linked directly with the Library itself.
+^L
+  6. As an exception to the Sections above, you may also combine or
+link a "work that uses the Library" with the Library to produce a
+work containing portions of the Library, and distribute that work
+under terms of your choice, provided that the terms permit
+modification of the work for the customer's own use and reverse
+engineering for debugging such modifications.
+
+  You must give prominent notice with each copy of the work that the
+Library is used in it and that the Library and its use are covered by
+this License.  You must supply a copy of this License.  If the work
+during execution displays copyright notices, you must include the
+copyright notice for the Library among them, as well as a reference
+directing the user to the copy of this License.  Also, you must do one
+of these things:
+
+    a) Accompany the work with the complete corresponding
+    machine-readable source code for the Library including whatever
+    changes were used in the work (which must be distributed under
+    Sections 1 and 2 above); and, if the work is an executable linked
+    with the Library, with the complete machine-readable "work that
+    uses the Library", as object code and/or source code, so that the
+    user can modify the Library and then relink to produce a modified
+    executable containing the modified Library.  (It is understood
+    that the user who changes the contents of definitions files in the
+    Library will not necessarily be able to recompile the application
+    to use the modified definitions.)
+
+    b) Use a suitable shared library mechanism for linking with the
+    Library.  A suitable mechanism is one that (1) uses at run time a
+    copy of the library already present on the user's computer system,
+    rather than copying library functions into the executable, and (2)
+    will operate properly with a modified version of the library, if
+    the user installs one, as long as the modified version is
+    interface-compatible with the version that the work was made with.
+
+    c) Accompany the work with a written offer, valid for at least
+    three years, to give the same user the materials specified in
+    Subsection 6a, above, for a charge no more than the cost of
+    performing this distribution.
+
+    d) If distribution of the work is made by offering access to copy
+    from a designated place, offer equivalent access to copy the above
+    specified materials from the same place.
+
+    e) Verify that the user has already received a copy of these
+    materials or that you have already sent this user a copy.
+
+  For an executable, the required form of the "work that uses the
+Library" must include any data and utility programs needed for
+reproducing the executable from it.  However, as a special exception,
+the materials to be distributed need not include anything that is
+normally distributed (in either source or binary form) with the major
+components (compiler, kernel, and so on) of the operating system on
+which the executable runs, unless that component itself accompanies
+the executable.
+
+  It may happen that this requirement contradicts the license
+restrictions of other proprietary libraries that do not normally
+accompany the operating system.  Such a contradiction means you cannot
+use both them and the Library together in an executable that you
+distribute.
+^L
+  7. You may place library facilities that are a work based on the
+Library side-by-side in a single library together with other library
+facilities not covered by this License, and distribute such a combined
+library, provided that the separate distribution of the work based on
+the Library and of the other library facilities is otherwise
+permitted, and provided that you do these two things:
+
+    a) Accompany the combined library with a copy of the same work
+    based on the Library, uncombined with any other library
+    facilities.  This must be distributed under the terms of the
+    Sections above.
+
+    b) Give prominent notice with the combined library of the fact
+    that part of it is a work based on the Library, and explaining
+    where to find the accompanying uncombined form of the same work.
+
+  8. You may not copy, modify, sublicense, link with, or distribute
+the Library except as expressly provided under this License.  Any
+attempt otherwise to copy, modify, sublicense, link with, or
+distribute the Library is void, and will automatically terminate your
+rights under this License.  However, parties who have received copies,
+or rights, from you under this License will not have their licenses
+terminated so long as such parties remain in full compliance.
+
+  9. You are not required to accept this License, since you have not
+signed it.  However, nothing else grants you permission to modify or
+distribute the Library or its derivative works.  These actions are
+prohibited by law if you do not accept this License.  Therefore, by
+modifying or distributing the Library (or any work based on the
+Library), you indicate your acceptance of this License to do so, and
+all its terms and conditions for copying, distributing or modifying
+the Library or works based on it.
+
+  10. Each time you redistribute the Library (or any work based on the
+Library), the recipient automatically receives a license from the
+original licensor to copy, distribute, link with or modify the Library
+subject to these terms and conditions.  You may not impose any further
+restrictions on the recipients' exercise of the rights granted herein.
+You are not responsible for enforcing compliance by third parties with
+this License.
+^L
+  11. If, as a consequence of a court judgment or allegation of patent
+infringement or for any other reason (not limited to patent issues),
+conditions are imposed on you (whether by court order, agreement or
+otherwise) that contradict the conditions of this License, they do not
+excuse you from the conditions of this License.  If you cannot
+distribute so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you
+may not distribute the Library at all.  For example, if a patent
+license would not permit royalty-free redistribution of the Library by
+all those who receive copies directly or indirectly through you, then
+the only way you could satisfy both it and this License would be to
+refrain entirely from distribution of the Library.
+
+If any portion of this section is held invalid or unenforceable under
+any particular circumstance, the balance of the section is intended to
+apply, and the section as a whole is intended to apply in other
+circumstances.
+
+It is not the purpose of this section to induce you to infringe any
+patents or other property right claims or to contest validity of any
+such claims; this section has the sole purpose of protecting the
+integrity of the free software distribution system which is
+implemented by public license practices.  Many people have made
+generous contributions to the wide range of software distributed
+through that system in reliance on consistent application of that
+system; it is up to the author/donor to decide if he or she is willing
+to distribute software through any other system and a licensee cannot
+impose that choice.
+
+This section is intended to make thoroughly clear what is believed to
+be a consequence of the rest of this License.
+
+  12. If the distribution and/or use of the Library is restricted in
+certain countries either by patents or by copyrighted interfaces, the
+original copyright holder who places the Library under this License
+may add an explicit geographical distribution limitation excluding those
+countries, so that distribution is permitted only in or among
+countries not thus excluded.  In such case, this License incorporates
+the limitation as if written in the body of this License.
+
+  13. The Free Software Foundation may publish revised and/or new
+versions of the Lesser General Public License from time to time.
+Such new versions will be similar in spirit to the present version,
+but may differ in detail to address new problems or concerns.
+
+Each version is given a distinguishing version number.  If the Library
+specifies a version number of this License which applies to it and
+"any later version", you have the option of following the terms and
+conditions either of that version or of any later version published by
+the Free Software Foundation.  If the Library does not specify a
+license version number, you may choose any version ever published by
+the Free Software Foundation.
+^L
+  14. If you wish to incorporate parts of the Library into other free
+programs whose distribution conditions are incompatible with these,
+write to the author to ask for permission.  For software which is
+copyrighted by the Free Software Foundation, write to the Free
+Software Foundation; we sometimes make exceptions for this.  Our
+decision will be guided by the two goals of preserving the free status
+of all derivatives of our free software and of promoting the sharing
+and reuse of software generally.
+
+                            NO WARRANTY
+
+  15. BECAUSE THE LIBRARY IS LICENSED FREE OF CHARGE, THERE IS NO
+WARRANTY FOR THE LIBRARY, TO THE EXTENT PERMITTED BY APPLICABLE LAW.
+EXCEPT WHEN OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR
+OTHER PARTIES PROVIDE THE LIBRARY "AS IS" WITHOUT WARRANTY OF ANY
+KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE
+IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
+PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE
+LIBRARY IS WITH YOU.  SHOULD THE LIBRARY PROVE DEFECTIVE, YOU ASSUME
+THE COST OF ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
+
+  16. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN
+WRITING WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY
+AND/OR REDISTRIBUTE THE LIBRARY AS PERMITTED ABOVE, BE LIABLE TO YOU
+FOR DAMAGES, INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR
+CONSEQUENTIAL DAMAGES ARISING OUT OF THE USE OR INABILITY TO USE THE
+LIBRARY (INCLUDING BUT NOT LIMITED TO LOSS OF DATA OR DATA BEING
+RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD PARTIES OR A
+FAILURE OF THE LIBRARY TO OPERATE WITH ANY OTHER SOFTWARE), EVEN IF
+SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH
+DAMAGES.
+
+                     END OF TERMS AND CONDITIONS
+^L
+           How to Apply These Terms to Your New Libraries
+
+  If you develop a new library, and you want it to be of the greatest
+possible use to the public, we recommend making it free software that
+everyone can redistribute and change.  You can do so by permitting
+redistribution under these terms (or, alternatively, under the terms
+of the ordinary General Public License).
+
+  To apply these terms, attach the following notices to the library.
+It is safest to attach them to the start of each source file to most
+effectively convey the exclusion of warranty; and each file should
+have at least the "copyright" line and a pointer to where the full
+notice is found.
+
+
+    <one line to give the library's name and a brief idea of what it does.>
+    Copyright (C) <year>  <name of author>
+
+    This library is free software; you can redistribute it and/or
+    modify it under the terms of the GNU Lesser General Public
+    License as published by the Free Software Foundation; either
+    version 2.1 of the License, or (at your option) any later version.
+
+    This library is distributed in the hope that it will be useful,
+    but WITHOUT ANY WARRANTY; without even the implied warranty of
+    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the GNU
+    Lesser General Public License for more details.
+
+    You should have received a copy of the GNU Lesser General Public
+    License along with this library; if not, write to the Free Software
+    Foundation, Inc., 59 Temple Place, Suite 330, Boston, MA 02111-1307  USA
+
+Also add information on how to contact you by electronic and paper mail.
+
+You should also get your employer (if you work as a programmer) or
+your school, if any, to sign a "copyright disclaimer" for the library,
+if necessary.  Here is a sample; alter the names:
+

+*************************
+
+Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
+2006 Free Software Foundation, Inc.
+
+This file is free documentation; the Free Software Foundation gives
+unlimited permission to copy, distribute and modify it.
+
+Basic Installation
+==================
+
+Briefly, the shell commands `./configure; make; make install' should
+configure, build, and install this package.  The following
+more-detailed instructions are generic; see the `README' file for
+instructions specific to this package.
+
+   The `configure' shell script attempts to guess correct values for
+various system-dependent variables used during compilation.  It uses
+those values to create a `Makefile' in each directory of the package.
+It may also create one or more `.h' files containing system-dependent
+definitions.  Finally, it creates a shell script `config.status' that
+you can run in the future to recreate the current configuration, and a
+file `config.log' containing compiler output (useful mainly for
+debugging `configure').
+
+   It can also use an optional file (typically called `config.cache'
+and enabled with `--cache-file=config.cache' or simply `-C') that saves
+the results of its tests to speed up reconfiguring.  Caching is
+disabled by default to prevent problems with accidental use of stale
+cache files.
+
+   If you need to do unusual things to compile the package, please try
+to figure out how `configure' could check whether to do them, and mail
+diffs or instructions to the address given in the `README' so they can
+be considered for the next release.  If you are using the cache, and at
+some point `config.cache' contains results you don't want to keep, you
+may remove or edit it.
+
+   The file `configure.ac' (or `configure.in') is used to create
+`configure' by a program called `autoconf'.  You need `configure.ac' if
+you want to change it or regenerate `configure' using a newer version
+of `autoconf'.
+
+The simplest way to compile this package is:
+
+  1. `cd' to the directory containing the package's source code and type
+     `./configure' to configure the package for your system.
+
+     Running `configure' might take a while.  While running, it prints
+     some messages telling which features it is checking for.
+
+  2. Type `make' to compile the package.
+
+  3. Optionally, type `make check' to run any self-tests that come with
+     the package.
+
+  4. Type `make install' to install the programs and any data files and
+     documentation.
+
+  5. You can remove the program binaries and object files from the
+     source code directory by typing `make clean'.  To also remove the
+     files that `configure' created (so you can compile the package for
+     a different kind of computer), type `make distclean'.  There is
+     also a `make maintainer-clean' target, but that is intended mainly
+     for the package's developers.  If you use it, you may have to get
+     all sorts of other programs in order to regenerate files that came
+     with the distribution.
+
+Compilers and Options
+=====================
+
+Some systems require unusual options for compilation or linking that the
+`configure' script does not know about.  Run `./configure --help' for
+details on some of the pertinent environment variables.
+
+   You can give `configure' initial values for configuration parameters
+by setting variables in the command line or in the environment.  Here
+is an example:
+
+     ./configure CC=c99 CFLAGS=-g LIBS=-lposix
+
+   *Note Defining Variables::, for more details.
+
+Compiling For Multiple Architectures
+====================================
+
+You can compile the package for more than one kind of computer at the
+same time, by placing the object files for each architecture in their
+own directory.  To do this, you can use GNU `make'.  `cd' to the
+directory where you want the object files and executables to go and run
+the `configure' script.  `configure' automatically checks for the
+source code in the directory that `configure' is in and in `..'.
+
+   With a non-GNU `make', it is safer to compile the package for one
+architecture at a time in the source code directory.  After you have
+installed the package for one architecture, use `make distclean' before
+reconfiguring for another architecture.
+
+Installation Names
+==================
+
+By default, `make install' installs the package's commands under
+`/usr/local/bin', include files under `/usr/local/include', etc.  You
+can specify an installation prefix other than `/usr/local' by giving
+`configure' the option `--prefix=PREFIX'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+pass the option `--exec-prefix=PREFIX' to `configure', the package uses
+PREFIX as the prefix for installing programs and libraries.
+Documentation and other data files still use the regular prefix.
+
+   In addition, if you use an unusual directory layout you can give
+options like `--bindir=DIR' to specify different values for particular
+kinds of files.  Run `configure --help' for a list of the directories
+you can set and what kinds of files go in them.
+
+   If the package supports it, you can cause programs to be installed
+with an extra prefix or suffix on their names by giving `configure' the
+option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
+
+Optional Features
+=================
+
+Some packages pay attention to `--enable-FEATURE' options to
+`configure', where FEATURE indicates an optional part of the package.
+They may also pay attention to `--with-PACKAGE' options, where PACKAGE
+is something like `gnu-as' or `x' (for the X Window System).  The
+`README' should mention any `--enable-' and `--with-' options that the
+package recognizes.
+
+   For packages that use the X Window System, `configure' can usually
+find the X include and library files automatically, but if it doesn't,
+you can use the `configure' options `--x-includes=DIR' and
+`--x-libraries=DIR' to specify their locations.
+
+Specifying the System Type
+==========================
+
+There may be some features `configure' cannot figure out automatically,
+but needs to determine by the type of machine the package will run on.
+Usually, assuming the package is built to be run on the _same_
+architectures, `configure' can figure that out, but if it prints a
+message saying it cannot guess the machine type, give it the
+`--build=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name which has the form:
+
+     CPU-COMPANY-SYSTEM
+
+where SYSTEM can have one of these forms:
+
+     OS KERNEL-OS
+
+   See the file `config.sub' for the possible values of each field.  If
+`config.sub' isn't included in this package, then this package doesn't
+need to know the machine type.
+
+   If you are _building_ compiler tools for cross-compiling, you should
+use the option `--target=TYPE' to select the type of system they will
+produce code for.
+
+   If you want to _use_ a cross compiler, that generates code for a
+platform different from the build platform, you should specify the
+"host" platform (i.e., that on which the generated programs will
+eventually be run) with `--host=TYPE'.
+
+Sharing Defaults
+================
+
+If you want to set default values for `configure' scripts to share, you
+can create a site shell script called `config.site' that gives default
+values for variables like `CC', `cache_file', and `prefix'.
+`configure' looks for `PREFIX/share/config.site' if it exists, then
+`PREFIX/etc/config.site' if it exists.  Or, you can set the
+`CONFIG_SITE' environment variable to the location of the site script.
+A warning: not all `configure' scripts look for a site script.
+
+Defining Variables
+==================
+
+Variables not defined in a site shell script can be set in the
+environment passed to `configure'.  However, some packages may run
+configure again during the build, and the customized values of these
+variables may be lost.  In order to avoid this problem, you should set
+them in the `configure' command line, using `VAR=value'.  For example:
+
+     ./configure CC=/usr/local2/bin/gcc
+
+causes the specified `gcc' to be used as the C compiler (unless it is
+overridden in the site shell script).
+
+Unfortunately, this technique does not work for `CONFIG_SHELL' due to
+an Autoconf bug.  Until the bug is fixed you can use this workaround:
+
+     CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
+
+`configure' Invocation
+======================
+
+`configure' recognizes the following options to control how it operates.
+
+`--help'
+`-h'
+     Print a summary of the options to `configure', and exit.
+
+`--version'
+`-V'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`--cache-file=FILE'
+     Enable the cache: use and save the results of the tests in FILE,
+     traditionally `config.cache'.  FILE defaults to `/dev/null' to
+     disable caching.
+
+`--config-cache'
+`-C'
+     Alias for `--cache-file=config.cache'.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.  To
+     suppress all normal output, redirect it to `/dev/null' (any error
+     messages will still be shown).
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`configure' also accepts some other, not widely useful, options.  Run
+`configure --help' for more details.

+
+
+Noteworthy changes in version 1.6.0 (2013-12-16) [C20/A0/R0]
+------------------------------------------------
+
+ * Removed the long deprecated gcry_ac interface.  Thus Libgcrypt is
+   not anymore ABI compatible to previous versions if they used the ac

+
+ * Removed the module register subsystem.
+
+ * The deprecated message digest debug macros have been removed.  Use
+   gcry_md_debug instead.

+   deprecated.  Use GCRY_PK_ECC if you need an algorithm id.
+
+ * Changed gcry_pk_genkey for "ecc" to only include the curve name and
+   not the parameters.  The flag "param" may be used to revert this.
+
+ * Added a feature to globally disable selected hardware features.
+
+ * Added debug helper functions.
+
+ * Interface changes relative to the 1.5.0 release:

+ * Support for WindowsCE.
+
+ * Support for ECDH.
+
+ * Support for OAEP and PSS methods as described by RFC-3447.
+
+ * Fixed PKCS v1.5 code to always return the leading zero.
+
+ * New format specifiers "%M" and "%u" for gcry_sexp_build.
+
+ * Support opaque MPIs with "%m" and "%M" in gcry_sexp_build.
+

+ * Uses the Intel AES-NI instructions if available.
+
+ * The use of the deprecated Alternative Public Key Interface
+   (gcry_ac_*) will now print compile time warnings.
+
+ * The module register subsystem has been deprecated.  This subsystem
+   is not flexible enough and would always require ABI changes to
+   extend the internal interfaces.  It will eventually be removed.
+   Please contact us on the gcrypt-devel mailing list to discuss
+   whether you really need this feature or how it can be replaced by
+   an internal plugin mechanism.
+
+ * CTR mode may now be used with data chunks of arbitrary length.

+   This functionality has been in Libgcrypt since 1.3.0.
+
+ * MD5 may now be used in non-enforced fips mode.
+
+ * Fixed HMAC for SHA-384 and SHA-512 with keys longer than 64 bytes.
+
+ * In fips mode, RSA keys are now generated using the X9.31 algorithm
+   and DSA keys using the FIPS 186-2 algorithm.
+
+ * The transient-key flag is now also supported for DSA key
+   generation.  DSA domain parameters may be given as well.
+
+
+Noteworthy changes in version 1.4.3 (2008-09-18)
+------------------------------------------------
+
+ * Try to auto-initialize Libgcrypt to minimize the effect of
+   applications not doing that correctly.  This is not a perfect
+   solution but given that many applicationion would totally fail
+   without such a hack, we try to help at least with the most common
+   cases.  Folks, please read the manual to learn how to properly
+   initialize Libgcrypt!
+
+ * Auto-initialize the secure memory to 32k instead of aborting the
+   process.
+
+ * Log fatal errors via syslog.
+
+ * Changed the name and the semantics of the fips mode config file.
+
+ * Add convenience macro gcry_fips_mode_active.
+
+ * More self-tests.
+
+ * Documentation cleanups.
+
+
+Noteworthy changes in version 1.4.2 (2008-09-08)
+------------------------------------------------
+
+ * The long missing gcry_mpi_lshift function has been added.
+
+ * RSA key generation now supports a "transient-key" flag.
+
+ * The keygrip computation for ECDSA has been implemented thus ECDSA
+   is now fully supported.
+
+ * A few macros have been replaced by functions for better type
+   checking.
+
+ * The thread initialization structure now carries version
+   information.
+
+ * The manual describes more clearly how to initialize Libgcrypt.
+
+ * The library may now be switched into a FIPS mode.
+
+ * Interface changes relative to the 1.3.0 release:

+Noteworthy changes in version 1.4.1 (2008-04-25)
+------------------------------------------------
+
+ * Fixed a bug introduced by 1.3.1 which led to the comsumption of far
+   too much entropy for the intial seeding.
+
+ * Improved AES performance for CFB and CBC modes.
+
+ * Removed build problems for the Padlock support.
+
+
+Noteworthy changes in version 1.4.0 (2007-12-10)
+------------------------------------------------
+
+ * New configure option --disable-padlock-support which is mostly
+   useful in case of build problems.
+
+
+Noteworthy changes in version 1.3.2 (2007-12-03)
+------------------------------------------------
+
+ * The visibility attribute is now used if supported by the toolchain.
+
+ * The ACE engine of VIA processors is now used for AES-128.
+
+ * The ASN.1 DER template for SHA-224 has been fixed.
+
+
+Noteworthy changes in version 1.3.1 (2007-10-26)
+------------------------------------------------
+
+ * The entire library is now under the LGPL. The helper programs and
+   the manual are under the GPL.  Kudos to Peter Gutmann for giving
+   permissions to relicense the rndw32 and rndunix modules.
+
+ * The Camellia cipher is now under the LGPL and included by default.
+
+ * Fixed a bug in the detection of symbol prefixes which inhibited the
+   build of optimzied assembler code on certain systems.
+
+ * Updated the entropy gatherer for W32.
+
+
+Noteworthy changes in version 1.3.0 (2007-05-04)
+------------------------------------------------
+
+ * Changed the way the RNG gets initialized. This allows to keep it
+   uninitialized as long as no random numbers are used.  To override
+   this, the new macro gcry_fast_random_poll may be used.  It is in
+   general a good idea to spread this macro into the application code
+   to make sure that these polls happen often enough.
+
+ * Made the RNG immune against fork without exec.
+
+ * Reading and writing the random seed file is now protected by a
+   fcntl style file lock on systems that provide this function.
+
+ * Support for SHA-224 and HMAC using SHA-384 and SHA-512.
+
+ * Support for the SEED cipher.
+
+ * Support for the Camellia cipher.  Note that Camellia is disabled by
+   default, and that enabling it changes the license of libgcrypt from
+   LGPL to GPL.
+
+ * Support for OFB encryption mode.
+
+ * gcry_mpi_rshift does not anymore truncate the shift count.
+
+ * Reserved algorithm ranges for use by applications.
+
+ * Support for DSA2.
+
+ * The new function gcry_md_debug should be used instead of the
+   gcry_md_start_debug and gcry_md_stop_debug macros.
+
+ * New configure option --enable-random-daemon to support a system
+   wide random daemon.  The daemon code is experimental and not yet
+   very well working.  It will eventually allow to keep a global
+   random pool for the sake of short living processes.
+
+ * Non executable stack support is now used by default on systems
+   supporting it.
+
+ * Support for Microsoft Windows.
+
+ * Assembler support for the AMD64 architecture.
+
+ * New configure option --enable-mpi-path for optimized builds.
+
+ * Experimental support for ECDSA; should only be used for testing.
+
+ * New control code GCRYCTL_PRINT_CONFIG to print the build
+   configuration.
+
+ * Minor changes to some function declarations.  Buffer arguments are
+   now typed as void pointer.  This should not affect any compilation.
+   Fixed two bugs in return values and clarified documentation.

+-------------------------------------------------
+
+ * The support for multi-threaded users goes into its third
+   incarnation.  We removed compile time support for thread libraries.
+   To support the thread library of your choice, you have to set up
+   callback handlers at initialization time.  New data structures, a
+   new control command, and default initializers are provided for this
+   purpose.

+
+
+Noteworthy changes in version 1.1.90 (2003-11-14)
+-------------------------------------------------
+
+ * The use of the GCRY_WEAK_RANDOM level is now deprecated in favor of
+   the new gcry_create_nonce function.
+
+ * gcry_sexp_build now supports a "%b" format to include a memory buffer.
+
+ * Minor configuration fixes.
+
+ * Interface changes relative to the 1.1.44 release:

+
+Noteworthy changes in version 1.1.43 (2003-09-04)
+-------------------------------------------------
+
+ * Bug fixes and internal code cleanups.
+
+ * Support for the Serpent cipher algorithm.
+
+ * Interface changes relative to the 1.1.42 release:
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+gcry_prime_generate             NEW
+gcry_prime_check                NEW
+
+
+Noteworthy changes in version 1.1.42 (2003-07-31)
+-------------------------------------------------
+
+ * Major API cleanup.  Applications need to be converted to the new
+   API.  See README.apichanges for hints on how to do that.  Backward
+   compatibility is provided where it was possible without too much
+   effort and did not collide with the overall sanitization effort.
+   However, this is only for ease of transition.  NO DEPRECATED
+   FUNCTION OR DATA TYPE IS CONSIDERED A PART OF THE API OR ABI AND
+   WILL BE DROPPED IN THE FUTURE WITHOUT CHANGING THE SONAME OF THE
+   LIBRARY.
+
+ * If gcrypt.h is included in sources compiled by GCC 3.1 or later,
+   deprecated attributes will warn about use of obsolete functions and
+   type definitions.  You can suppress these warnings by passing
+   -Wno-deprecated-declarations to the gcc command.
+
+ * gcry_check_version must be called from now on to initialize the
+   library, it is not longer optional.
+
+ * Removed `libgcrypt errno' concept.
+
+ * Libgcrypt depends on libgpg-error, a library that provides error
+   codes and according functions for all GnuPG components.  Functions
+   that used to return error codes asa `int' have been changed to
+   return a code of type `gcry_error_t'.  All GCRYERR_* error symbols
+   have been removed, since they are now contained in libgpg-error
+   (GPG_ERR_*). All functions and types in libgpg-error have also been
+   wrapped in Libgcrypt. The new types are gcry_err_code_t and
+   gcry_err_source_t.  The new functions are gcry_err_code,
+   gcry_err_source, gcry_error, gcry_err_make, gcry_error_from_errno,
+   gcry_err_make_from_errno, gcry_err_code_from_errno,
+   gcry_err_code_to_errno, gcry_strsource.
+
+ * New function gcry_mpi_dump to help in debugging.
+
+ * Added alternative interface for asymmetric cryptography.
+
+ * CRC-32, CRC-32 a'la RFC 1510, CRC-24 a'la RFC 2440 are now
+   supported.
+
+ * SHA-256, SHA-384 and SHA-512 are now supported.
+
+ * 128 bit Twofish is now supported.
+
+ * The random module won't print the "not enough random bytes
+   available" anymore.  A new progress status is issued instead.
+
+ * CBC-MAC for block ciphers is now supported, by using a
+   GCRY_CIPHER_CBC_MAC cipher flag.
+
+ * CTR mode for block ciphers is now supported.
+
+ * The public RSA exponent can now be specified in key generation.
+
+ * RSA blinding is now supported and is used automatically for RSA
+   decryption.  It can be explicitely disabled by using the
+   `no-blinding' symbol in the `flags' S-Expression or by using the
+   GCRY_AC_FLAG_DATA_NO_BLINDING flag when using the ac interface.
+
+ * gcry_sexp_canon_len does not use a `historically encoded' error
+   code anymore.
+
+
+ * Interface changes relative to the 1.1.12 release:

+
+
+    Overview
+    --------
+
+    Libgcrypt is a general purpose crypto library based on the code
+    used in GnuPG.  Libgcrypt depends on the library `libgpg-error',
+    which must be installed correctly before Libgcrypt is to be built.
+    Libgcrypt is distributed under the LGPL, see the section "License"
+    below for details.
+
+
+    Build Instructions
+    ------------------
+
+    The download canonical location for libgcrypt is:
+
+      ftp://ftp.gnupg.org/gcrypt/libgcrypt/
+
+    To build libgcrypt you need libgpg-error:
+
+      ftp://ftp.gnupg.org/gcrypt/libgpg-error/
+
+    You should get the latest versions of course.
+
+    After building and installing the libgpg-error package, you may
+    continue with Libgcrypt installation as with allmost all GNU
+    packages, you just have to do
+
+       ./configure
+       make
+       make check
+       make install
+
+    The "make check" is not required but a good idea to see whether
+    the library works as expected.  The check takes some while and
+    prints some benchmarking results.  Before doing "make install" you
+    probably need to become root.
+
+    To build libgcrypt for Microsoft Windows, you need to have the
+    mingw32 cross-building toolchain installed.  Instead of running a
+    plain configure you use
+
+      ./autogen.sh --build-w32
+      make
+      make install
+
+    By default this command sequences expectsd a libgpg-error
+    installed below $HOME/w32root and installs libgcrypt to that
+    directory too.  See the autogen.sh code for details.
+
+    The documentation is available as an Info file (gcrypt.info).  To
+    build documentation in PDF, run this:
+
+      cd doc
+      make pdf
+
+
+
+    Mailing List
+    ------------
+
+    You may want to join the developer's mailing list
+    gcrypt-devel@gnupg.org by sending mail with a subject of
+    "subscribe" to gcrypt-devel-request@gnupg.org.  An archive of this
+    list is available at http://lists.gnupg.org .
+
+
+    Configure options
+    -----------------
+    Here is a list of configure options which are sometimes useful
+    for installation.
+
+     --enable-large-data-tests
+                     With this option a "make check" will take really
+                     long due to extra checks for the hash algorithms.
+
+     --enable-m-guard
+                     Enable the integrated malloc checking code. Please
+                     note that this feature does not work on all CPUs
+                     (e.g. SunOS 5.7 on UltraSparc-2) and might give
+                     you a bus error.
+
+     --disable-asm
+                     Do not use assembler modules.  It is not possible
+                     to use this on some CPU types.
+
+     --enable-ld-version-script
+                     Libgcrypt tries to build a library where internal
+                     symbols are not exported.  This requires support
+                     from ld and is currently enabled for a few OSes.
+                     If you know that your ld supports the so called
+                     ELF version scripts, you can use this option to
+                     force its use.  OTOH, if you get error message
+                     from the linker, you probably want to use this
+                     option to disable the use of version scripts.
+                     Note, that you should never ever use an
+                     undocumented symbol or one which is prefixed with
+                     an underscore.
+
+     --enable-ciphers=list
+     --enable-pubkey-ciphers=list
+     --enable-digests=list
+                     If not otherwise specified, all algorithms
+                     included in the libgcrypt source tree are built.
+		     An exception are algorithms, which depend on
+		     features not provided by the system, like 64bit
+		     data types.  With these switches it is possible
+                     to select exactly those algorithm modules, which
+		     should be built.  The algorithms are to be
+                     separated by spaces, commas or colons.  To view
+                     the list used with the current build the program
+                     tests/version may be used.
+
+     --disable-endian-check
+                     Don't let configure test for the endianness but
+                     try to use the OS provided macros at compile
+                     time.  This is helpful to create OS X fat binaries.
+
+     --enable-random-daemon
+                     Include support for a global random daemon and
+                     build the daemon.  This is an experimental feature.
+
+     --enable-mpi-path=EXTRA_PATH
+                     Prepend EXTRA_PATH to list of CPU specific
+                     optimizations.  For example, if you want to add
+                     optimizations forn a Intel Pentium 4 compatible
+                     CPU, you may use
+                        --enable-mpi-path=pentium4/sse2:pentium4/mmx
+                     Take care: The generated library may crash on
+                     non-compatible CPUs.
+
+     --enable-random=NAME
+                     Force the use of the random gathering module
+		     NAME.  Default is either to use /dev/random or
+		     the auto mode.  Possible values for NAME are:
+		       egd - Use the module which accesses the
+			     Entropy Gathering Daemon. See the webpages
+			     for more information about it.
+		      unix - Use the standard Unix module which does not
+			     have a very good performance.
+		     linux - Use the module which accesses /dev/random.
+			     This is the first choice and the default one
+			     for GNU/Linux or *BSD.
+                      auto - Compile linux, egd and unix in and
+                             automagically select at runtime.
+
+     --enable-hmac-binary-check
+                     Include support to check the binary at runtime
+                     against a HMAC checksum.  This works only in FIPS
+                     mode and on systems providing the dladdr function.
+
+     --disable-padlock-support
+                     Disable support for the PadLock engine of VIA
+                     processors.  The default is to use PadLock if
+                     available.  Try this if you get problems with
+                     assembler code.
+
+     --disable-aesni-support
+                     Disable support for the AES-NI instructions of
+                     newer Intel CPUs.  The default is to use AES-NI
+                     if available.  Try this if you get problems with
+                     assembler code.
+
+     --disable-O-flag-munging
+                     Some code is too complex for some compilers while
+                     in higher optimization modes, thus the compiler
+                     invocation is modified to use a lower
+                     optimization level.  Usually this works very well
+                     but on some platforms these rules break the
+                     invocation.  This option may be used to disable
+                     the feature under the assumption that either good
+                     CFLAGS are given or the compiler can grok the code.
+
+
+
+
+    Build Problems
+    --------------
+
+    We can't check all assembler files, so if you have problems
+    assembling them (or the program crashes) use --disable-asm with
+    ./configure.  If you opt to delete individual replacement files in
+    hopes of using the remaining ones, be aware that the configure
+    scripts may consider several subdirectories to get all available
+    assembler files; be sure to delete the correct ones.  Never delete
+    udiv-qrnnd.S in any CPU directory, because there may be no C
+    substitute (in mpi/genereic).  Don't forget to delete
+    "config.cache" and run "./config.status --recheck".  We got a few
+    reports about problems using versions of gcc earlier than 2.96
+    along with a non-GNU assembler (as).  If this applies to your
+    platform, you can either upgrade gcc to a more recent version, or
+    use the GNU assembler.
+
+    Some make tools are broken - the best solution is to use GNU's
+    make.  Try gmake or grab the sources from a GNU archive and
+    install them.
+
+    Specific problems on some machines:
+
+      * IBM RS/6000 running AIX
+
+	Due to a change in gcc (since version 2.8) the MPI stuff may
+	not build. In this case try to run configure using:
+	    CFLAGS="-g -O2 -mcpu=powerpc" ./configure
+
+      * SVR4.2 (ESIX V4.2 cc)
+
+        Due to problems with the ESIX as(1), you probably want to do:
+            CFLAGS="-O -K pentium" ./configure --disable-asm
+
+      * SunOS 4.1.4
+
+         ./configure ac_cv_sys_symbol_underscore=yes
+
+      * Sparc64 CPUs
+
+        We have reports about failures in the AES module when
+        compiling using gcc (e.g. version 4.1.2) and the option -O3;
+        using -O2 solves the problem.

+
+    This library used to be available under the GPL - this was changed
+    with version 1.1.7 with the rationale that there are now many free
+    crypto libraries available and many of them come with capabilities
+    similar to Libcrypt.  We decided that to foster the use of
+    cryptography in Free Software an LGPLed library would make more
+    sense because it avoids problems due to license incompatibilities
+    between some Free Software licenses and the GPL.
+
+    Please note that in many cases it is better for a library to be
+    licensed under the GPL, so that it provides an advantage for free
+    software projects.  The Lesser GPL is so named because it does
+    less to protect the freedom of the users of the code that it
+    covers.  See http://www.gnu.org/philosophy/why-not-lgpl.html for
+    more explanation.

+If you are building from GIT, run the script
+
+./autogen.sh
+
+first, to make sure that you have all the necessary maintainer tools
+are installed and to build the actual configuration files.  If you
+have just checked out from GIT, you should add the option "--force" to
+autogen.sh so that meta data is noticed by autom4te.cache.  Then run
+
+./configure --enable-maintainer-mode
+
+followed by the usual make.
+
+If autogen.sh complains about insufficient versions of the required
+tools, or the tools are not installed, you may use environment
+variables to override the default tool names:
+
+ AUTOMAKE_SUFFIX  is used as a suffix for all tools from the automake
+                  package.  For example
+                     AUTOMAKE_SUFFIX="-1.7" ./autogen.sh
+                  uses "automake-1.7" and "aclocal-1.7.
+ AUTOMAKE_PREFIX  is used as a prefix for all tools from the automake
+                  page and may be combined with AUTOMAKE_SUFFIX. e.g.:
+                    AUTOMAKE_PREFIX=/usr/foo/bin ./autogen.sh
+                  uses "automake" and "aclocal" in the /usr/foo/bin
+                  directory.
+ AUTOCONF_SUFFIX  is used as a suffix for all tools from the automake
+                  package
+ AUTOCONF_PREFIX  is used as a prefix for all tools from the automake
+                  package
+ GETTEXT_SUFFIX   is used as a suffix for all tools from the gettext
+                  package
+ GETTEXT_PREFIX   is used as a prefix for all tools from the gettext
+                  package
+
+It is also possible to use the variable name AUTOMAKE, AUTOCONF,
+ACLOCAL, AUTOHEADER, GETTEXT and MSGMERGE to directly specify the name
+of the programs to run.  It is however better to use the suffix and
+prefix forms as described above because that does not require
+knowledge about the actual tools used by autogen.sh.
+
+
+Please don't use autopoint, libtoolize or autoreconf unless you are
+the current maintainer and want to update the standard configuration
+files.  All those files should be in GIT and only updated manually
+if the maintainer decides that newer versions are required.  The
+maintainer should also make sure that the required version of automake
+et al. are properly indicated at the top of configure.ac and take care
+to copy the files and not merely use symlinks.

+* Add attributes to the MPI functions.
+
+* cipher/pubkey.c and pubkey implementaions.
+  Don't rely on the secure memory based wiping function but add an
+  extra wiping.
+  
+* Use builtin bit functions of gcc 3.4
+
+* Consider using a daemon to maintain the random pool
+  [Partly done] The down side of this is that we can't assume that the
+  random has has always been stored in "secure memory".  And we rely
+  on that sniffing of Unix domain sockets is not possible.  We can
+  implement this simply by detecting a special prefixed random seed
+  name and divert in this case to the daemon.  There are several
+  benefits with such an approach: We keep the state of the RNG over
+  invocations of libgcrypt based applications, don't need time
+  consuming initialization of the pool and in case the entropy
+  collectros need to run that bunch of Unix utilities we don't waste
+  their precious results.
+
+* gcryptrnd.c
+  Requires a test for pth [done] as well as some other tests.
+
+* secmem.c
+  Check whether the memory block is valid before releasing it and
+  print a diagnosic, like glibc does.
+
+* threads
+** We need to document fork problems
+  In particular that reinitialization is required in random.c
+  However, there is no code yet to do it.
+
+* Tests
+  We need a lot more tests.  Lets keep an ever growing list here.
+** Write tests for the progress function
+** mpitests does no real checks yet.
+** pthreads
+  To catch simple errors like the one fixed on 2007-03-16.
+** C++ tests
+  We have some code to allow using libgcrypt from C++, so we also
+  should have a test case.

+##   -MM, not -M (despite what the docs say).  Also, it might not be
+##   supported by the other compilers which use the 'gcc' depmode.
+## - Using -M directly means running the compiler twice (even worse

+## This next piece of magic avoids the "deleted header file" problem.
+## The problem is that when a header file which appears in a .P file
+## is deleted, the dependency causes make to die (because there is
+## typically no way to rebuild the header).  We avoid this by adding
+## dummy dependencies for each header file.  Too bad gcc doesn't do
+## this for us directly.
+## Some versions of gcc put a space before the ':'.  On the theory
+## that the space means something, we add a space to the output as
+## well.  hp depmode also adds that space, but also prefixes the VPATH
+## to the object.  Take care to not repeat it in the output.
