+		    GNU GENERAL PUBLIC LICENSE
+		       Version 2, June 1991
+
+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.
+               59 Temple Place, Suite 330, 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 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) 19yy  <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  02110-1301  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) 19yy 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:
+
+  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
+  `Gnomovision' (which makes passes at compilers) written by James Hacker.
+
+  <signature of Ty Coon>, 1 April 1989
+  Ty Coon, President of Vice
+
+This General Public License does not permit incorporating your program into
+proprietary programs.  If your program is a subroutine library, you may
+consider it more useful to permit linking proprietary applications with the
+library.  If this is what you want to do, use the GNU Library General
+Public License instead of this License.

+abakus, by Michael Pyne <michael.pyne@kdemail.net>
+Version: 0.91
+
+This is my attempt at creating a light-calculator based on Roberto Alsina's
+initial usability suggestions, and based on the ideas of a few other KDE
+hackers.
+
+This software is distributed under the terms of the GNU GPL v2.
+
+Synopsis:
+ $ tar xvjf abakus-0.91.tar.bz2
+ $ cd abakus-0.91
+ $ ./configure && make && make install
+ $ abakus
+
+Type away, and press Enter to see the result.
+
+Changes since 0.90:
+* Add ability to remove all functions and variables to the context menus of
+  their respective list boxes.
+* Convert out-of-range numbers to NaN.
+* Accept "," as a decimal separator for the benefit of European users.
+* Use correct decimal separator (per KLocale settings) in output.
+* For long results, show the beginning instead of the end of the result,
+  since the beginning is the most significant part of the result.
+
+Changes since 0.85:
+* You now have the option of using the GNU Multiple Precision library for
+  high-precision mathematics.  It requires the MPFR library to also be
+  installed (normally comes with GNU MP 4.x).  It is used automatically if
+  detected.
+* Jes Hall has contributed DocBook documentation to make Abakus integrate into
+  KDE even more tightly.  Thanks, Jes!
+* User defined functions can now be defined over.
+* Error handling with deriv() function improved.
+* Ariya Hidayat's name was misspelled everywhere in Abakus.  Sorry, Ariya. :(
+* Speaking of Ariya, Abakus now uses the impressive user interface code from
+  his SpeedCrunch calculator (http://speedcrunch.berlios.de/).  This includes
+  the Calc-as-you-Type tooltip, the function and variable dropdown, and
+  syntax highlighting.  It's not configurable at this point, expect that in
+  the next release.
+* You can use the F6 key to select the expression editor if you're a big fan
+  of the keyboard.
+* Raising negative numbers to integral powers should work with the internal
+  high-precision library now.
+* You can no longer deselect the current precision menu item.
+* Fix crash bug when a user-defined function refers to another user-defined
+  function, and then you remove or edit the function it referred to.
+* Add exact numerical derivatives for all functions supported.
+* Added the asinh, acosh, and atanh functions.
+* Fixed bug with loading of prior compact mode status.
+* Fixed bug where result text had wrong precision when you changed the
+  precision and tried drag-and-drop.
+* Drag-and-drop improvements.
+* Fixed bug where Custom Precision menu entry was checked even if you canceled
+  the dialog.
+* Made hyperbolic functions consistently ignore trigonometric mode.  (Both
+  Degrees and Radians make no sense for hyperbolic trig).
+* Whew! :)
+
+v0.85 adds a lot:
+* Improvements to the configure script.  Since I didn't end up using libCLN it
+  was mostly for naught, but the changes will be useful for the future.
+* abakus now uses the high-precision math routines from Ariya Hidayat's
+  SpeedCrunch program.  Thanks, Ariya!
+* High precision arithmetic can have between 0 and 75 digits of precision.
+* Support for approximate derivatives.  For most functions the derivatives will
+  be numerically accurate.  For those functions where I didn't feel like typing
+  in the exact form of the derivative an approximation is used instead.
+* Implicit multiplication has been added to the parser.  That means you can
+  type stuff like "3 sin pi" without having to manually add the * in between
+  3 and sin.  This also works with numbers and variables, and numbers and
+  parenthesized expressions.
+* GUI changes.  The main result view now uses KListView, so it gains tooltip
+  support for long answers for free, along with a bevy of other improvements.
+* You can right-click on an answer and copy it to the clipboard.
+* Corrected information in the about box.
+* Restarting abakus with compact mode enabled should is much improved.
+
+v0.80.2 fixed an issue with the configure script for people who don't have
+exactly the same version of Python I do, and forcibly prevents flex/bison
+errors.
+
+v0.80.1 fixed an issue with the configure script for people who don't already
+have scons installed.
+
+Major changes since 0.76:
+* There is no more C code to interface between the parser and program.
+* RPN mode is improved.  Now the stack is retained between calls, and there
+  are a few commands only in RPN mode:
+    1. pop   - Return the top of the stack.
+    2. clear - Clear the stack.
+* bksys is used instead of the custom Makefiles.
+* Lots of code cleanups, including license headers.
+* The nifty drag-and-drop image looks more rectangular, and is used with the
+  two listviews on the right as well.
+* Improved error checking, with messages that should hopefully be more
+  descriptive.
+
+Major changes since 0.75:
+* Reorder internal macro so that functions are declared *before* they're
+  referenced, which helps build the program on systems with math.h files that
+  don't export the long double version of their math functions.
+* Hitting a number or letter key right after evaluating an expression in RPN
+  mode automatically prepends the 'ans' variable, which was a feature of the
+  Normal mode.
+
+Major changes since 0.70:
+* Build system switched (somehow) to using qmake.  The parser and lexer are
+  still included, so bison and flex are still not required.  Hopefully this
+  will improve the ease of building.  Of course, this means no more colored
+  make output.
+* Changed most of the keyboard shortcuts to use Shift + Alt + foo instead of
+  Alt + foo since that was interfering with the menu bar.
+* RPN mode!!  If you enable RPN mode, then your expressions will be evaluated
+  using the Reverse Polish Notation popular with users of HP calculators.  Note
+  that although you can use values and functions while in RPN mode, you cannot
+  set or remove them from the expression editor like you can in normal mode.
+* abakus will display a small token starting with a dollar sign ($) in italics
+  next to results.  You can use these tokens to quickly reference a result in
+  your expression.  The most recent result is always $0, with the number
+  increasing from most recent to least recent result.  For example, typing
+  2 <Enter> 3 <Enter> $0 ^ $1 <Enter> would give a result of 9.
+* You can right click on functions and values in the list views to remove them
+  from the GUI.
+* Changed the result items to use word wrapping when needed to fit all the
+  text.
+* Very small DCOP interface.
+* More code cleanup.
+* Added a .desktop file.
+* Test client removed again.
+* Double-clicking on an error message (or OK message) no longer inserts them
+  into the edit box.
+
+Major changes since 0.61:
+* User defined Functions.
+* Save state of program between runs.
+* Miscellaneous fun stuff.
+
+Currently implemented features:
+* Parser built using flex and bison.  The generated files are included so it
+  should compile fine for you.
+* Fully C++.  The parser and lexer code require C++ to compile.
+* Supports several built-in functions:
+   - sin, cos, tan, sinh, cosh, tanh, asin, acos, atan in either radian or
+         degree mode.
+     abs, exp (e raised to the given power), ln, log (base 10),
+     sqrt, ceil, floor
+* Supported operators: +, -, *, /, ^ (or **).
+* Includes a window showing the values and user-defined functions you have.
+* Predefined constants: pi, and e (Euler' constant).
+* You can assign to variables by using an expression of the form:
+  identifier = expression.  You can then reuse these variables later.
+* You can create user-defined functions of one variable using the syntax
+  set foo(var) = <expr>, where <expr> calculates the value in terms of var.
+* You can delete user-defined variables by doing: remove var
+* You can delete user-defined functions by doing: remove foo().  Notice that
+  the variable is NOT included in that expression.
+* Functions and variables are saved on exit, and then loaded when abakus is
+  started again.
+* The ans variable contains the result of the last computation.
+* Pressing +, -, *, or / immediately after your last computation automatically
+  inserts ans for you, saving you typing.
+* A compact mode for the program.
+* Operator precedence should be correct, including the right association of
+  the power operator.  So, 2 ^ 3 ^ 2 == 512, just as it does when you write
+  it out.  You can use parentheses to force precedence.
+* Parentheses are not required around functions.  So, sin 3 is a valid
+  expression.  Note that sin 3 + cos 4 translates internally as (sin 3) + 
+  (cos 4), not as sin (3 + cos (4)).
+* I took some pains to try to make things like 3 + -2 work right.
+* inf and nan are accepted as numeric input for completeness.
+* abakus will automatically add ) characters to the end of the expression as
+  needed to balance your expression.  This means that expressions like
+  sin (cos (2 + 3 will evaluate with no error.
+* A rudimentary RPN mode is included.  Most everything works, except for
+  derivatives and creating functions or new variables.
+
+Bugs:
+* More functions would be nice.
+* The lexer assumes that the decimal marker is a period. (.)  I'm not exactly
+  sure how to cleanly solve this problem with flex. :-(
+* Documentation could be better.
