CHANGES MADE TO MATHOMATIC V12.8.9 TO MAKE MATHOMATIC VERSION 12.9.0:

Documentation and code cleanup.

3/6/08 - Added demo "tests/circles.in", completes in 1 second!

3/7/08 - Made all error text the color red when color mode is enabled.

3/8/08 - Made "set true_modulus" the default.

3/13/08 - Implemented integral divide operator "//" which divides and truncates result to an integer.
          This operator is handy for doing integer arithmetic.

3/16/08 - Made all warning text the color yellow.

CHANGES MADE TO MATHOMATIC V12.9.0:

3/27/08 - Deleted outdated "doc/notes.html".

3/29/08 - Set command allows the following option prefix words: no, not, off, false, yes, on, true.

3/30/08 - Updated matho-primes to work with architectures that don't support long double.

CHANGES MADE TO MATHOMATIC V12.9.1:

Some minor corrections were made.

4/5/08 - Turned off readline file name completion, tab is now just a tab.

CHANGES MADE TO MATHOMATIC V12.9.2:

4/20/08 - Read set options in either "~/.mathomaticrc" or "mathomatic.rc" when starting up under Cygwin.

4/23/08 - A major fix was made to the simplify command, it was not expanding fractions enough.

CHANGES MADE TO MATHOMATIC V14.0.0:

Code and documentation cleanup.

Disallow variable name "all" in expressions.  "all" means all normal variables and is a reserved word now.

4/25/08 - Set command parser now reports errors properly.

4/28/08 - More correct simplification restriction added: (x^n)^m remains unsimplified unless "symbolic" option is used.
          This was documented but not fully implemented.  You need to use "simplify symbolic" to simplify like before.

CHANGES MADE TO MATHOMATIC V14.0.1:

4/30/08 - The calculate command user interface was corrected.

5/4/08 - Added "simplify sign" command option, which conveniently expands all "sign" variables and simplifies.

CHANGES MADE TO MATHOMATIC V14.0.2:

Code cleanup.

5/16/08 - Added "derivative nosimplify" command option, which does absolutely no simplification after differentiating.
          Fixed the taylor command to work with larger equations with more derivatives by simplifying better.
