+ GNU LESSER GENERAL PUBLIC LICENSE
+ Version 3, 29 June 2007
+
+ Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
+ Everyone is permitted to copy and distribute verbatim copies
+ of this license document, but changing it is not allowed.
+
+
+ This version of the GNU Lesser General Public License incorporates
+the terms and conditions of version 3 of the GNU General Public
+License, supplemented by the additional permissions listed below.
+
+ 0. Additional Definitions.
+
+ As used herein, "this License" refers to version 3 of the GNU Lesser
+General Public License, and the "GNU GPL" refers to version 3 of the GNU
+General Public License.
+
+ "The Library" refers to a covered work governed by this License,
+other than an Application or a Combined Work as defined below.
+
+ An "Application" is any work that makes use of an interface provided
+by the Library, but which is not otherwise based on the Library.
+Defining a subclass of a class defined by the Library is deemed a mode
+of using an interface provided by the Library.
+
+ A "Combined Work" is a work produced by combining or linking an
+Application with the Library. The particular version of the Library
+with which the Combined Work was made is also called the "Linked
+Version".
+
+ The "Minimal Corresponding Source" for a Combined Work means the
+Corresponding Source for the Combined Work, excluding any source code
+for portions of the Combined Work that, considered in isolation, are
+based on the Application, and not on the Linked Version.
+
+ The "Corresponding Application Code" for a Combined Work means the
+object code and/or source code for the Application, including any data
+and utility programs needed for reproducing the Combined Work from the
+Application, but excluding the System Libraries of the Combined Work.
+
+ 1. Exception to Section 3 of the GNU GPL.
+
+ You may convey a covered work under sections 3 and 4 of this License
+without being bound by section 3 of the GNU GPL.
+
+ 2. Conveying Modified Versions.
+
+ If you modify a copy of the Library, and, in your modifications, a
+facility refers to a function or data to be supplied by an Application
+that uses the facility (other than as an argument passed when the
+facility is invoked), then you may convey a copy of the modified
+version:
+
+ a) under this License, provided that you make a good faith effort to
+ ensure that, in the event an Application does not supply the
+ function or data, the facility still operates, and performs
+ whatever part of its purpose remains meaningful, or
+
+ b) under the GNU GPL, with none of the additional permissions of
+ this License applicable to that copy.
+
+ 3. Object Code Incorporating Material from Library Header Files.
+
+ The object code form of an Application may incorporate material from
+a header file that is part of the Library. You may convey such object
+code under terms of your choice, provided that, if the incorporated
+material is not limited to numerical parameters, data structure
+layouts and accessors, or small macros, inline functions and templates
+(ten or fewer lines in length), you do both of the following:
+
+ a) Give prominent notice with each copy of the object code that the
+ Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the object code with a copy of the GNU GPL and this license
+ document.
+
+ 4. Combined Works.
+
+ You may convey a Combined Work under terms of your choice that,
+taken together, effectively do not restrict modification of the
+portions of the Library contained in the Combined Work and reverse
+engineering for debugging such modifications, if you also do each of
+the following:
+
+ a) Give prominent notice with each copy of the Combined Work that
+ the Library is used in it and that the Library and its use are
+ covered by this License.
+
+ b) Accompany the Combined Work with a copy of the GNU GPL and this license
+ document.
+
+ c) For a Combined Work that displays copyright notices during
+ execution, include the copyright notice for the Library among
+ these notices, as well as a reference directing the user to the
+ copies of the GNU GPL and this license document.
+
+ d) Do one of the following:
+
+ 0) Convey the Minimal Corresponding Source under the terms of this
+ License, and the Corresponding Application Code in a form
+ suitable for, and under terms that permit, the user to
+ recombine or relink the Application with a modified version of
+ the Linked Version to produce a modified Combined Work, in the
+ manner specified by section 6 of the GNU GPL for conveying
+ Corresponding Source.
+
+ 1) Use a suitable shared library mechanism for linking with the
+ Library. A suitable mechanism is one that (a) uses at run time
+ a copy of the Library already present on the user's computer
+ system, and (b) will operate properly with a modified version
+ of the Library that is interface-compatible with the Linked
+ Version.
+
+ e) Provide Installation Information, but only if you would otherwise
+ be required to provide such information under section 6 of the
+ GNU GPL, and only to the extent that such information is
+ necessary to install and execute a modified version of the
+ Combined Work produced by recombining or relinking the
+ Application with a modified version of the Linked Version. (If
+ you use option 4d0, the Installation Information must accompany
+ the Minimal Corresponding Source and Corresponding Application
+ Code. If you use option 4d1, you must provide the Installation
+ Information in the manner specified by section 6 of the GNU GPL
+ for conveying Corresponding Source.)
+
+ 5. Combined Libraries.
+
+ 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 that are not Applications and are not covered by this
+License, and convey such a combined library under terms of your
+choice, if you do both of the following:
+
+ a) Accompany the combined library with a copy of the same work based
+ on the Library, uncombined with any other library facilities,
+ conveyed under the terms of this License.
+
+ b) Give prominent notice with the combined library that part of it
+ is a work based on the Library, and explaining where to find the
+ accompanying uncombined form of the same work.
+
+ 6. Revised Versions of the GNU Lesser General Public License.
+
+ The Free Software Foundation may publish revised and/or new versions
+of the GNU 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 as you received it specifies that a certain numbered version
+of the GNU Lesser General Public License "or any later version"
+applies to it, you have the option of following the terms and
+conditions either of that published version or of any later version
+published by the Free Software Foundation. If the Library as you
+received it does not specify a version number of the GNU Lesser
+General Public License, you may choose any version of the GNU Lesser
+General Public License ever published by the Free Software Foundation.
+
+ If the Library as you received it specifies that a proxy can decide
+whether future versions of the GNU Lesser General Public License shall
+apply, that proxy's public statement of acceptance of any version is
+permanent authorization for you to choose that version for the
+Library.

+ lib@name@ - The @NAME@ library
+ ------------------------------------
+
+ Overview
+ --------
+
+ <tell something about this library>
+
+ License
+ -------
+
+ Most of this library is distributed under the terms of the GNU
+ Lesser General Public License (LGPL); see the file COPYING for
+ the actual terms.
+
+ Configure options
+ -----------------
+
+ Here is a list of configure options which are sometimes useful
+ for installation.
+
+ --enable-debug
+ Make the library more noise and do more runtime checks.
+ This will slow down the library at runtime.
+
+ --enable-profiling
+ Build the library with profiling support.
+
+ --enable-coverage
+ Build the library with coverage support.
+
+ --disable-hide
+ Built the library with all internal symbols visible. The
+ default is to only provide the exported functions to a
+ user. When --enable-debug is given all internal symbols
+ are visible.
+
+ Environment Variables
+ ---------------------
+
+ You can overwrite CPPFLAGS, CFLAGS and LDFLAGS from the environment. But
+ keep in mind to not forget to add the "-O2 -g", if you use your own CFLAGS
+ settings. Only in the case CFLAGS is unset, configure defaults to "-O2 -g"

+# Check here for mandadory external libraries
+#
+# Rule of thumb: when your library needs an external library, add it
+# to the 'LIBS' variable. Do _not_ add it manually into the Makefile.am files.
+# These libraries _must_ be listed in the *.pc file.
+#
+# Don't add libraries without a check. Even if you know the 'sqrt()' requires
+# 'libm' on most systems, check for its real need with 'AC_SEARCH_LIBS(sqrt, m)'.
+# Doing it in this way will ensure an embedded developer knows exactly what
+# dependencies your library has (because it get listed in the *.pc file).
+#
+# Another way for checking libraries is the PKG_CHECK_MODULES macro. But please
+# honor if a user switches off a feature you also switch of the test for a
+# external component via PKG_CHECK_MODULES when it is no longer required!
+# PKG_CHECK_MODULES returns *_CFLAGS and *_LIBS. Again, add the *_LIBS to the
+# global 'LIBS', but for the CFLAGS you can decide if you add them to the
+# CFLAGS, AM_CFLAGS or as substitution variables in the Makefile.am.
+#
+
+#
+# Check for functions and header files. First write your code and then run
+# the 'autoscan' tool to get an idea what is still missing in your 'configure.ac'

+ lib@name@ - The @NAME@ library
+ ------------------------------------
+
+ Overview
+ --------
+
+ <tell something about this library>
+
+ License
+ -------
+
+ <define the license of this library>; see the file COPYING for the
+ actual terms.
+
+ Configure options
+ -----------------
+
+ Here is a list of configure options which are sometimes useful
+ for installation.
+
+ --enable-debug
+ Make the library more noise and do more runtime checks.
+ This will slow down the library at runtime.
+
+ --enable-profiling
+ Build the library with profiling support.
+
+ --enable-coverage
+ Build the library with coverage support.
+
+ --disable-hide
+ Built the library with all internal symbols visible. The
+ default is to only provide the exported functions to a
+ user. When --enable-debug is given all internal symbols
+ are visible.
+
+ <add more switches on demand here>
+
+ Environment Variables
+ ---------------------
+
+ You can overwrite CPPFLAGS, CFLAGS and LDFLAGS from the environment. But
+ keep in mind to not forget to add the "-O2 -g", if you use your own CFLAGS
+ settings. Only in the case CFLAGS is unset, configure defaults to "-O2 -g"

+# These libraries _must_ be listed in the *.pc file.
+#
+# Don't add libraries without a check. Even if you know the 'sqrt()' requires
+# 'libm' on most systems, check for its real need with 'AC_SEARCH_LIBS(sqrt, m)'.
+# Doing it in this way will ensure an embedded developer knows exactly what
+# dependencies your library has (because it get listed in the *.pc file).
+#
+# Another way for checking libraries is the PKG_CHECK_MODULES macro. But please
+# honor if a user switches off a feature you also switch of the test for a
+# external component via PKG_CHECK_MODULES when it is no longer required!
+# PKG_CHECK_MODULES returns *_CFLAGS and *_LIBS. Again, add the *_LIBS to the
+# global 'LIBS', but for the CFLAGS you can decide if you add them to the
+# CFLAGS, AM_CFLAGS or as substitution variables in the Makefile.am.
+#
+
+#
+# Check for functions and header files. First write your code and then run
+# the 'autoscan' tool to get an idea what is still missing in your 'configure.ac'
