+The Academic Free License
+v. 2.1
+
+This Academic Free License (the "License") applies to any original work of authorship (the "Original Work") whose owner (the "Licensor") has placed the following notice immediately following the copyright notice for the Original Work:
+
+Licensed under the Academic Free License version 2.1
+
+1) Grant of Copyright License. Licensor hereby grants You a world-wide, royalty-free, non-exclusive, perpetual, sublicenseable license to do the following:
+
+a) to reproduce the Original Work in copies;
+
+b) to prepare derivative works ("Derivative Works") based upon the Original Work;
+
+c) to distribute copies of the Original Work and Derivative Works to the public;
+
+d) to perform the Original Work publicly; and
+
+e) to display the Original Work publicly.
+
+2) Grant of Patent License. Licensor hereby grants You a world-wide, royalty-free, non-exclusive, perpetual, sublicenseable license, under patent claims owned or controlled by the Licensor that are embodied in the Original Work as furnished by the Licensor, to make, use, sell and offer for sale the Original Work and Derivative Works.
+
+3) Grant of Source Code License. The term "Source Code" means the preferred form of the Original Work for making modifications to it and all available documentation describing how to modify the Original Work. Licensor hereby agrees to provide a machine-readable copy of the Source Code of the Original Work along with each copy of the Original Work that Licensor distributes. Licensor reserves the right to satisfy this obligation by placing a machine-readable copy of the Source Code in an information repository reasonably calculated to permit inexpensive and convenient access by You for as long as Licensor continues to distribute the Original Work, and by publishing the address of that information repository in a notice immediately following the copyright notice that applies to the Original Work.
+
+4) Exclusions From License Grant. Neither the names of Licensor, nor the names of any contributors to the Original Work, nor any of their trademarks or service marks, may be used to endorse or promote products derived from this Original Work without express prior written permission of the Licensor. Nothing in this License shall be deemed to grant any rights to trademarks, copyrights, patents, trade secrets or any other intellectual property of Licensor except as expressly stated herein. No patent license is granted to make, use, sell or offer to sell embodiments of any patent claims other than the licensed claims defined in Section 2. No right is granted to the trademarks of Licensor even if such marks are included in the Original Work. Nothing in this License shall be interpreted to prohibit Licensor from licensing under different terms from this License any Original Work that Licensor otherwise would have a right to license.
+
+5) This section intentionally omitted.
+
+6) Attribution Rights. You must retain, in the Source Code of any Derivative Works that You create, all copyright, patent or trademark notices from the Source Code of the Original Work, as well as any notices of licensing and any descriptive text identified therein as an "Attribution Notice." You must cause the Source Code for any Derivative Works that You create to carry a prominent Attribution Notice reasonably calculated to inform recipients that You have modified the Original Work.
+
+7) Warranty of Provenance and Disclaimer of Warranty. Licensor warrants that the copyright in and to the Original Work and the patent rights granted herein by Licensor are owned by the Licensor or are sublicensed to You under the terms of this License with the permission of the contributor(s) of those copyrights and patent rights. Except as expressly stated in the immediately proceeding sentence, the Original Work is provided under this License on an "AS IS" BASIS and WITHOUT WARRANTY, either express or implied, including, without limitation, the warranties of NON-INFRINGEMENT, MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS TO THE QUALITY OF THE ORIGINAL WORK IS WITH YOU. This DISCLAIMER OF WARRANTY constitutes an essential part of this License. No license to Original Work is granted hereunder except under this disclaimer.
+
+8) Limitation of Liability. Under no circumstances and under no legal theory, whether in tort (including negligence), contract, or otherwise, shall the Licensor be liable to any person for any direct, indirect, special, incidental, or consequential damages of any character arising as a result of this License or the use of the Original Work including, without limitation, damages for loss of goodwill, work stoppage, computer failure or malfunction, or any and all other commercial damages or losses. This limitation of liability shall not apply to liability for death or personal injury resulting from Licensor's negligence to the extent applicable law prohibits such limitation. Some jurisdictions do not allow the exclusion or limitation of incidental or consequential damages, so this exclusion and limitation may not apply to You.
+
+9) Acceptance and Termination. If You distribute copies of the Original Work or a Derivative Work, You must make a reasonable effort under the circumstances to obtain the express assent of recipients to the terms of this License. Nothing else but this License (or another written agreement between Licensor and You) grants You permission to create Derivative Works based upon the Original Work or to exercise any of the rights granted in Section 1 herein, and any attempt to do so except under the terms of this License (or another written agreement between Licensor and You) is expressly prohibited by U.S. copyright law, the equivalent laws of other countries, and by international treaty. Therefore, by exercising any of the rights granted to You in Section 1 herein, You indicate Your acceptance of this License and all of its terms and conditions.
+
+10) Termination for Patent Action. This License shall terminate automatically and You may no longer exercise any of the rights granted to You by this License as of the date You commence an action, including a cross-claim or counterclaim, against Licensor or any licensee alleging that the Original Work infringes a patent. This termination provision shall not apply for an action alleging patent infringement by combinations of the Original Work with other software or hardware.
+
+11) Jurisdiction, Venue and Governing Law. Any action or suit relating to this License may be brought only in the courts of a jurisdiction wherein the Licensor resides or in which Licensor conducts its primary business, and under the laws of that jurisdiction excluding its conflict-of-law provisions. The application of the United Nations Convention on Contracts for the International Sale of Goods is expressly excluded. Any use of the Original Work outside the scope of this License or after its termination shall be subject to the requirements and penalties of the U.S. Copyright Act, 17 U.S.C. § 101 et seq., the equivalent laws of other countries, and international treaty. This section shall survive the termination of this License.
+
+12) Attorneys Fees. In any action to enforce the terms of this License or seeking damages relating thereto, the prevailing party shall be entitled to recover its costs and expenses, including, without limitation, reasonable attorneys' fees and costs incurred in connection with such action, including any appeal of such action. This section shall survive the termination of this License.
+
+13) Miscellaneous. This License represents the complete agreement concerning the subject matter hereof. If any provision of this License is held to be unenforceable, such provision shall be reformed only to the extent necessary to make it enforceable.
+
+14) Definition of "You" in This License. "You" throughout this License, whether in upper or lower case, means an individual or a legal entity exercising rights under, and complying with all of the terms of, this License. For legal entities, "You" includes any entity that controls, is controlled by, or is under common control with you. For purposes of this definition, "control" means (i) the power, direct or indirect, to cause the direction or management of such entity, whether by contract or otherwise, or (ii) ownership of fifty percent (50%) or more of the outstanding shares, or (iii) beneficial ownership of such entity.
+
+15) Right to Use. You may use the Original Work in all ways not otherwise restricted or conditioned by this License or by law, and Licensor promises not to interfere with or be responsible for such uses by You.

+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+               51 Franklin Street, Fifth Floor, Boston, MA  02110-1301  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 tqcontains
+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 tqcontains 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 tqcontains, 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.>

+Basic Installation
+==================
+
+   These are generic installation instructions.
+
+   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, a file
+`config.cache' that saves the results of its tests to speed up
+reconfiguring, and a file `config.log' containing compiler output
+(useful mainly for debugging `configure').
+
+   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 at some point `config.cache'
+tqcontains results you don't want to keep, you may remove or edit it.
+
+   The file `configure.in' is used to create `configure' by a program
+called `autoconf'.  You only need `configure.in' 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.  If you're
+     using `csh' on an old version of System V, you might need to type
+     `sh ./configure' instead to prevent `csh' from trying to execute
+     `configure' itself.
+
+     Running `configure' takes a while.  While running, it prints some
+     messages telling which features it is checking for.
+
+  2. Type `gmake' to compile the package.  Or if you're using a Linux
+     powered machine, or if make is GNU make, type `make'.  You can
+     check with make --version.  KDE requires GNU make to build, if 
+     gmake is appropriate, tqreplace any instance below of make with gmake.
+     It will give output similar to:
+        #make --version
+        GNU Make version 3.78.1, by Richard Stallman and Roland McGrath.
+        Built for i386--freebsd4.0
+        Copyright (C) 1988, 89, 90, 91, 92, 93, 94, 95, 96, 97, 98, 99
+        ...
+
+  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.  You can give `configure'
+initial values for variables by setting them in the environment.  Using
+a Bourne-compatible shell, you can do that on the command line like
+this:
+     CC=c89 CFLAGS=-O2 LIBS=-lposix ./configure
+
+Or on systems that have the `env' program, you can do it like this:
+     env CPPFLAGS=-I/usr/local/include LDFLAGS=-s ./configure
+
+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 must use a version of `make' that
+supports the `VPATH' variable, such as 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 `..'.
+
+   If you have to use a `make' that does not supports the `VPATH'
+variable, you have 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' will install the package's files in
+`/usr/local/kde/bin', `/usr/local/kde/lib', etc.  You can specify an
+installation prefix other than `/usr/local/kde' by giving `configure'
+the option `--prefix=PATH'.
+
+   You can specify separate installation prefixes for
+architecture-specific files and architecture-independent files.  If you
+give `configure' the option `--exec-prefix=PATH', the package will use
+PATH as the prefix for installing programs and libraries.
+Documentation and other data files will still use the regular prefix.
+
+   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
+tqfind 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' can not figure out
+automatically, but needs to determine by the type of host the package
+will run on.  Usually `configure' can figure that out, but if it prints
+a message saying it can not guess the host type, give it the
+`--host=TYPE' option.  TYPE can either be a short name for the system
+type, such as `sun4', or a canonical name with three fields:
+     CPU-COMPANY-SYSTEM
+
+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 host type.
+
+   If you are building compiler tools for cross-compiling, you can also
+use the `--target=TYPE' option to select the type of system they will
+produce code for and the `--build=TYPE' option to select the type of
+system on which you are compiling the package.
+
+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.
+
+Operation Controls
+==================
+
+   `configure' recognizes the following options to control how it
+operates.
+
+`--cache-file=FILE'
+     Use and save the results of the tests in FILE instead of
+     `./config.cache'.  Set FILE to `/dev/null' to disable caching, for
+     debugging `configure'.
+
+`--help'
+     Print a summary of the options to `configure', and exit.
+
+`--quiet'
+`--silent'
+`-q'
+     Do not print messages saying which checks are being made.
+
+`--srcdir=DIR'
+     Look for the package's source code in directory DIR.  Usually
+     `configure' can determine that directory automatically.
+
+`--version'
+     Print the version of Autoconf used to generate the `configure'
+     script, and exit.
+
+`configure' also accepts some other, not widely useful, options.

+This is a backport of Harald Fernengel's Qt4 D-Bus bindings.
+
+Some Qt4 based code had no direct equivalent in Qt3. Cases where this
+transition to Qt3 might not be fully correct are marked with FIXME-QT4
+
+Depending on the use case it might be necessary to extend QDBusMesssage
+to allow marshalling/de-marshalling based on an application provided
+helper as the Qt3 QVariant can not handle all cases the Qt4 pendant can
+(user defined types, etc)

+/**
+ * @mainpage TQt3 Bindings for D-Bus

+ *
+ * For more information about D-Bus itself see its website:
+ * http://www.freedesktop.org/wiki/Software_2fdbus
+ *
+ * The TQt3 D-Bus bindings described here are a TQt3 style API around the base
+ * implementation to enable TQt3 developers to use D-Bus in their applications
+ * without requiring them to know about the details of the C based D-Bus API.
+ *
+ * The two main use cases are:
+ * - using the API to access service implemented in other applications.
+ *   See section @ref dbusclient for an introduction on this
+ *
+ * - using the API to provide access to services implemented in your application
+ *   See section @ref dbusservice for an introduction on this
+ *
+ * Of course an application can do both at the same time.
+ */
+
+/**
+ * @page dbusconventions Naming and syntax conventions in D-Bus
+ *
+ * @section dbusconventions-servicename Service names
+ *
+ * The service name is D-Bus application identifier, i.e. either
+ * the unique name handed out to the peer application by the bus on connect
+ * (see TQT_DBusConnection::uniqueName()) or, more likely, a well known name the
+ * peer application has requested, see TQT_DBusConnection::requestName()
+ *
+ * Such well known names have the form of word separated by dots, like
+ * Internet domain names but in reverse order.
+ *
+ * For example the name for the bus itself (the D-Bus daemon) would be
+ * @code
+ *   "org.freedesktop.DBus"
+ * @endcode
+ *
+ * @section dbusconventions-objectpath Object paths
+ *
+ * The object path is like an address within the peer host application.
+ * The path format looks like a Unix file path, i.e. words separated by
+ * slash @c '/' characters.
+ *
+ * For example the path for the bus itself (the D-Bus daemon's main object)
+ * would be
+ * @code
+ *   "/org/freedesktop/DBus"
+ * @endcode
+ *
+ * @section dbusconventions-interfacename Interface names
+ *
+ * The interface name specifies which group of methods and signals
+ * implemented by the peer service object is used in proxy operations.
+ *
+ * Interface names have the form of word separated by dots, like Internet
+ * domain names but in reverse order or like a fully qualified Java class name.
+ *
+ * For example the interface for the bus itself (the D-Bus daemon's main
+ * interface) would be
+ * @code
+ *   "org.freedesktop.DBus"
+ * @endcode
+ *
+ * @section dbusconventions-errorname Error names
+ *
+ * A D-Bus error name is a sequence of words separated by dots, similar
+ * to D-Bus service names or interface names, or like a fully qualified
+ * Java class name.
+ *
+ * For example if a D-Bus service does not handle a method invocation sent
+ * to it because it doesn't know about the method it will return a D-Bus
+ * error named
+ * @code
+ *   "org.freedesktop.DBus.Error.UnknownMethod"
+ * @endcode
+ * TQT_DBusError can create some of the more common errors based on a type value
+ * and decode their names into the type respectively. See TQT_DBusError#ErrorType
+ *
+ * @section dbusconventions-membername Method and signal names
+ *
+ * There is no mandatory convention for member names, neither for methods nor
+ * for signals.
+ *
+ * However, using the standard interfaces of D-Bus as a hint, it is recommended
+ * to use "camel case" names starting with an uppercase letter, for example
+ * @code
+ *   "GetConnectionUnixUser"
+ * @endcode

+/**
+ * @brief Provides access to a specific D-Bus bus
+ *
+ * In order to access a D-Bus message bus an application has to connect to it.
+ * This is very similar to connecting to an FTP server using TQFtp, where any
+ * number of commands can be sent in sequence over the same connection.
+ *
+ * Additionally to the asynchronous command execution provided by TQFtp a
+ * TQT_DBusConnection can also execute synchronous (blocking) calls so the
+ * code around those calls stays closer to in-process method incovations.
+ *
+ * However it is recommended to only perform blocking calls on D-Bus service
+ * methods that are likely to be processed fast.
+ *
+ * TQT_DBusConnection implements a shared resource, i.e. if you create a
+ * connection with a specific name in one part of your code and then
+ * create one with the same name somewhere else, the second creation will
+ * actually return the same shared connection object the first caller created.
+ *
+ * The application can be connected to more than one message bus simultaniously
+ * using one or more connections per bus, however the most common case is to
+ * have one connection per bus.
+ *
+ * The two main bus types are:
+ * - System bus: a bus connecting applications on one system across user
+ *               or session boundaries, for example allowing to communicate
+ *               with system services like printer spoolers, etc
+ *
+ * - Session bus: a bus connecting applications within one user session, for
+ *                example started at login or by a session manager. Use cases
+ *                or this kind of bus would be accessing user specific
+ *                resources like addressbooks, retrieving user settings or
+ *                controlling session services (e.g. disabling screensaver
+ *                in a video player application during playback)
+ *
+ * While TQT_DBusConnection provides the basic API to access D-Bus services
+ * it is more convenient to use TQT_DBusProxy on top of the connection.
+ *
+ * See sections @ref dbusclient and @ref dbusservice for examples

+/**
+ * @brief Template based converter for getting complex data into or from TQT_DBusData objects
+ *
+ * Any data to transport over D-Bus, i.e. method/signal paramaters or properties, need
+ * to be converted into a TQT_DBusData instance.
+ * 
+ * For complex types, e.g. structures or nested containers, this can be quite some code,
+ * and will likely be needed for more than one call.
+ * Therefore it is more convenient to implement the conversions once per complex type.
+ *
+ * Example: sending and recieving a TQRect over D-Bus.
+ * In D-Bus terminology a TQRect is a struct of four 32-bit signed integers. The code to do
+ * this manually looks like this:
+ * @code
+ * TQRect rect(0, 0, 100, 100);
+ * 
+ * TQValueList<TQT_DBusData> structMembers;
+ * structMembers << TQT_DBusData::fromInt32(rect.x());
+ * structMembers << TQT_DBusData::fromInt32(rect.y());
+ * structMembers << TQT_DBusData::fromInt32(rect.wdth());
+ * structMembers << TQT_DBusData::fromInt32(rect.height());
+ *
+ * TQT_DBusData rectStruct = TQT_DBusData::fromStruct(structMembers);
+ * @endcode
+ * and reverse (without the error checking)
+ * @code
+ * TQT_DBusData dbusData; // assume we got this from a D-Bus call
+ * 
+ * TQValueList<TQT_DBusData> structMembers = dbudData.toStruct();
+ * 
+ * int x = structMembers[0].toInt32();
+ * int y = structMembers[1].toInt32();
+ * int w = structMembers[2].toInt32();
+ * int h = structMembers[3].toInt32();
+ *
+ * TQRect rect(x, y, w, h);
+ * @endcode
+ *
+ * Rather than implementing it in the method which performs the D-Bus call, basically the same
+ * code can be used as a spezialisation of the TQT_DBusDataConverter methods and then used like this:
+ * @code
+ * TQRect rect(0, 0, 100, 100);
+ * TQT_DBusData rectStruct;
+ *
+ * TQT_DBusDataConverter::convertToTQT_DBusData<TQRect>(rect, rectStruct);
+ * @endcode
+ * and
+ * @code
+ * TQRect rect;
+ * TQT_DBusData dbusData; // assume we got this from a D-Bus call
+ *
+ * TQT_DBusDataConverter::convertFromTQT_DBusData<TQRect>(dbusData, rect);
+ * @endcode
+ *
+ * @note The bindings library tqcontains the spezialisations for TQRect, TQPoint and TQSize.

+ *       implementation is more list like.
+ *
+ * There are basically two ways to create TQT_DBusDataList objects:
+ * - non-empty from content
+ * - empty by specifying the desired element type
+ *
+ * Example for creating a filled list from content
+ * @code
+ * TQValueList<TQ_INT16> intList;
+ * list << 2 << 3 << 5 << 7;
+ *
+ * TQT_DBusDataList dbusList(intList);
+ * TQT_DBusData data = TQT_DBusData::fromList(dbusList);
+ *
+ * // or even shorter, using implicit conversion
+ * TQT_DBusData other = TQT_DBusData::fromList(intList);
+ * @endcode
+ *
+ * Example for creating an empty list
+ * @code
+ * // empty list for a simple type
+ * TQT_DBusDataList list(TQT_DBusData::Double);
+ *
+ * // empty list for a list of string lists
+ * TQT_DBusData elementType = TQT_DBusData::fromList(TQT_DBusDataList(TQT_DBusData::String));

+/**
+ * @brief A message converts and transports data over D-Bus
+ *
+ * A TQT_DBusMessage is implicitly shared, similar to a TQString, i.e. copying
+ * a message creates just a shallow copy.
+ *
+ * The TQT_DBusMessage is the TQt3 bindings means of encapsulating data for a
+ * method call, a method reply or an error.
+ *
+ * Data specifying the sender and receipient is directly accessible through
+ * getter methods, while data, e.g. method parameters or return values, are
+ * managed as a list of TQT_DBusData.
+ *
+ * To create a message suitable for sending use one of the static factory
+ * methods:
+ * - signal() for creating a D-Bus signal message
+ *
+ * - methodCall() for creating a D-Bus method calls to a service object
+ *
+ * - methodReply() for creating a method reply on success
+ *
+ * - methodError() for creating a method reply on error
+ *
+ * @note for applications that just want to perform method calls and/or receive
+ *       signals, it is usually more convenient to use TQT_DBusProxy instead.
+ *
+ * Message sending is achieved through TQT_DBusConnection
+ *
+ * Example:
+ * @code
+ *   TQT_DBusConnection con = TQT_DBusConnection::sessionBus();
+ *
+ *   // receipient service is the bus' main interface
+ *
+ *   TQString service   = "org.freedesktop.DBus";
+ *   TQString path      = "/org/freedesktop/DBus";
+ *   TQString interface = "org.freedesktop.DBus";
+ *
+ *   TQT_DBusMessage msg = TQBusMessage::methodCall(service, path, interface, "ListNames");
+ *
+ *   TQT_DBusMessage reply = con.sendWithReply(msg);
+ *
+ *   // awaiting for a message list
+ *
+ *   if (reply.type() != TQT_DBusMessage::ReplyMessage || reply.count() != 2 ||
+ *       reply[0].type() != TQT_DBusData::List)
+ *   {
+ *       // error handling here
+ *   }
+ *   else
+ *   {
+ *       TQStringList list = reply[0].toTQStringList();
+ *
+ *       // reply handling here
+ *   }
+ * @endcode
+ *
+ * A service returning such a reply would do something like this
+ * @code
+ *   bool Service::handleMethodCall(const TQT_DBusMessage& call)
+ *   {
+ *       // checks for correctness, i.e. correct interface, member,
+ *       // would usually haven been placed here
+ *
+ *       TQStringList result;
+ *       result << "Foo" << "Bar";
+ *
+ *       TQT_DBusMessage reply = TQT_DBusMessage::methodReply(call);
+ *       reply << TQT_DBusData::fromList(result);
+ *
+ *       connection.send(reply);

+ *
+ * @section dbusservice-requestname Requesting service name
+ *
+ * When an application connects to D-Bus it gets a unique name generated by
+ * the bus daemon.
+ *
+ * However, an application providing service will often want to be reachable
+ * under a fixed name, like a webserver being reachable through a domain name
+ * independent from its actual IP address.
+ * See section @ref dbusconventions-servicename for details on service names.
+ *
+ * In order to get such a specific name an application has to request it
+ * using TQT_DBusConnection::requestName()
+ *
+ * The example above request @c "org.example.SortService" but continues with
+ * the default unique name in the case some other application is currently
+ * owning that name.
+ *
+ * @section dbusservice-registerobjects Registering objects
+ *
+ * To make service objects available to other applications on the same
+ * bus the application has to register the objects instances with the
+ * connection to the bus using TQT_DBusConnection::registerObject()
+ *
+ * Registering means to specify an object path where the object will be
+ * located, i.e. how it can be unambiguously be addressed in method calls.
+ * See section @ref dbusconventions-objectpath for details on object paths.
+ *
+ * If the applications has introspectable objects it is recommended to
+ * register an introspectable root object, i.e. using @c "/" as the path, so
+ * other applications have a common place to start asking for introspection
+ * data.
+ *
+ * In the example above a service object providing sorting services on lists is
+ * registered on the path @c "/ListSorter"
+ *
+ * @section dbusservice-interfaces Service interfaces
+ *
+ * D-Bus methods and signals of a service object a grouped into interfaces.
+ *
+ * See section @ref dbusconventions-interfacename for details on interface
+ * naming.
+ *
+ * An object can implement any number of interfaces, for example the interface
+ * for the functionality it wants to provide and a D-Bus standard interface like
+ * @c "org.freedesktop.DBus.Introspectable" for providing an XML description of
+ * all its interfaces.
+ *
+ *
+ * The service object of the example above implements just one interface
+ * @c "org.example.Sort" and its handleMethodCall() explicitly checks all
+ * received messages and rejects any messsage not sent to this particular
+ * interface by returning @c false and thus telling the D-Bus layer to
+ * generate a standard error response.
+ *
+ * Multiple interfaces can of course be directly implemented in one C++ class,
+ * however it might sometimes be wise to delegate calls for different
+ * interfaces to different implementations:
+ * @code
+ *   class Interface1 : public TQT_DBusObjectBase
+ *   {
+ *   public:
+ *       Interface1(const TQT_DBusConnection&);
+ *
+ *   protected:
+ *       virtual bool handleMethodCall(const TQT_DBusMessage&);
+ *   };

+ *   public:
+ *       Interface2(const TQT_DBusConnection&);

+ *   };

+ *   {
+ *       m_interfaces.insert("org.example.Interface1", new Interface1(connection));
+ *       m_interfaces.insert("org.example.Interface2", new Interface2(connection));
+ *   }

+ * @section dbusclient-introduction Introduction
+ *
+ * While it is of course possible to just exchange D-Bus messages with a
+ * D-Bus service, it is a lot more comfortable to use TQT_DBusProxy.
+ *
+ * With TQT_DBusProxy you only need to specify the service object once, i.e.
+ * its D-Bus name, path and interface, and just provide the method and its
+ * parameters when initiating an invokation.
+ *
+ * Additionally the proxy transforms D-Bus signals from the proxy's peer
+ * (the D-Bus service object's interface it is associated with) to TQObject
+ * signal carrying the original signal's content.
+ *
+ * @section dbusclient-example A simple D-Bus client example
+ *
+ * @code
+ *   #include <dbus/tqdbusconnection.h>
+ *   #include <dbus/tqdbusmessage.h>
+ *   #include <dbus/tqdbusproxy.h>
+ *
+ *   int main()
+ *   {
+ *       // establish a connection to the session bus
+ *
+ *       TQT_DBusConnection connection = TQT_DBusConnection::sessionBus();
+ *       if (!connection.isConnected())
+ *           qFatal("Failed to connect to session bus");
+ *
+ *       // create a proxy object for method calls
+ *
+ *       TQT_DBusProxy proxy(connection);
+ *       proxy.setService("org.freedesktop.DBus");   // who we work with
+ *       proxy.setPath("/org/freedesktop/DBus");     // which object inside the peer work with
+ *       proxy.setInterface("org.freedesktop.DBus"); // which of its interfaces we will use
+ *
+ *       // call the "ListNames" method. It returns an array of string, in TQt3 terms
+ *       // a TQStringList, it expects no parameters
+ *
+ *       TQValueList<TQT_DBusData> params;
+ *       TQT_DBusMessage reply = proxy.sendWithReply("ListNames", params);
+ *
+ *       if (reply.type() != TQT_DBusMessage::ReplyMessage)
+ *           qFatal("Call failed");
+ *
+ *       if (reply.count() != 1 || reply[0].type() != TQT_DBusData::List)
+ *           qFatal("Unexpected reply");
+ *
+ *       bool ok = false;
+ *       TQStringList names = reply[0].toTQStringList(&ok);
+ *
+ *       if (!ok) qFatal("Unexpected reply");
+ *
+ *       for (TQStringList::iterator it = names.begin(); it != names.end(); ++it)
+ *       {
+ *           qDebug("%s", (*it).local8Bit().data());
+ *       }
+ *
+ *       return 0;
+ *   }
+ * @endcode
+ *
+ * @section dbusclient-initialization Program initialization
+ *
+ * A connection to the bus is acquired using TQT_DBusConnection::sessionBus()
+ *
+ * Next, a proxy is created for the object @c "/org/freedesktop/DBus" with
+ * interface @c "org.freedesktop.DBus" on the service @c "org.freedesktop.DBus"
+ *
+ * This is a proxy for the message bus itself.
+ *
+ * @section dbusclient-methodcall Method invocation
+ *
+ * There are two choices for method invocation:
+ * - sychronous (blocking) calls
+ * - asynchronous (non-blocking) calls
+ *
+ * @subsection dbusclient-synccall Synchronous method calls
+ *
+ * As seen in the example code above, a synchronous method call can be achieved
+ * by TQT_DBusProxy::sendWithReply(). It sends a method call to the remote object,
+ * and blocks until reply is received. The outgoing arguments are specified as
+ * a list of TQT_DBusData.
+ *
+ * @subsection dbusclient-asynccall Asynchronous method calls
+ *
+ * To invoke a method asynchronously, connect the proxy's signal
+ * TQT_DBusProxy::asyncReply(int, const TQT_DBusMessage&) to a suitable slot like
+ * with any other TQt Signal-Slot connection.
+ *
+ * Then call TQT_DBusProxy::sendWithAsyncReply()
+ * It returns a numerical identifier of the call, so it can be related in the
+ * slot once the result is available.
+ *
+ * The slot's first argument is the reveived reply's call identifier as
+ * returned by the method call. The second parameter is the reply message
+ * similar to the one in the synchronous call.
+ *
+ * @note For asynchronous calls you'll need a running event loop, i.e. a
+ * TQApplication object and its exec() having been invoked.
+ *
+ * @section dbusclient-signals Connecting to D-Bus signals
+ *
+ * To receive D-BUS signals just connect to the TQT_DBusProxy's signal
+ * TQT_DBusProxy::dbusSignal(const TQT_DBusMessage&)
+ *
+ * It will be emitted whenever a D-Bus signal message is received from the peer
+ * object.
+ * Filtering of signals is based on the value set for @c service, @c path and
+ * @c interface
+ *
+ * @note Filtering for @c service will only happen if @c service is a unique
+ *       D-Bus name, i.e. if it starts with a colon @c ":" since D-Bus signals
+ *       carry the sender's unique name and filtering by a requested name
+ *       would reject all signals
+ *
+ * Usually a proxy will be also be used to send to the peer object, thus having
+ * them all set. However if a proxy is only needed for signals, any of the
+ * three properties can be omitted (e.g. set to @c TQString() ), in which
+ * case only the available properties will be checked against the respective
+ * message field when deciding about dropping or emitting the message.
+ * See TQT_DBusProxy::handleDBusSignal()
+ *
+ * If you want all signal travelling on the bus, or apply filtering for
+ * different criteria, e.g. get all signals coming from interfaces starting
+ * with @c "org.", use @c TQT_DBusConnection::connect() instead.
+ * The signature of the slot stays the same.
+ *
+ * @subsection dbusclient-signals-example Signal example
+ *
+ * First declare a receiver class:
+ * @code
+ *   class MyReceiver : public TQObject
+ *   {
+ *       TQ_OBJECT
+ *   public slots:
+ *       void handleDBusSignal(const TQT_DBusMessage&);
+ *   };
+ * @endcode
+ * Then somewhere else in a source file:
+ * @code
+ *   TQT_DBusConnection connection = TQT_DBusConnection::sessionBus();
+ *
+ *   MyReceiver* receiver1 = new MyReceiver();
+ *
+ *   connection.connect(receiver1, TQT_SLOT(handleDBusSignal(const TQT_DBusMessage&)));
+ * @endcode
+ * @c receiver1 will get all signals on this connection
+ *
+ * @code
+ *   TQT_DBusProxy* proxy = new TQT_DBusProxy(connection);
+ *   proxy->setService("org.freedesktop.DBus");   // who we work with
+ *   proxy->setPath("/org/freedesktop/DBus");     // which object inside the peer work with
+ *   proxy->setInterface("org.freedesktop.DBus"); // which of its interfaces we will use
+ *
+ *   MyReceiver* receiver2 = new MyReceiver();
+ *
+ *   TQObject::connect(proxy,     TQT_SIGNAL(dbusSignal(const TQT_DBusMessage&)),
+ *                    receiver2, TQT_SLOT(handleDBusSignal(const TQT_DBusMessage&)));
+ * @endcode
+ * @c receiver2 will only get signals coming from the proxy's peer interface
