Log message:
Update mathomatic to 11.7.

Changes:

Another minor adjustment to simplify command to make everything work
just right.

Trap "derivative x" of (negative constant or zero)^x.

Solve "(constant)^y=constant" for y.

Moved all html files and the man page to subdirectory "doc".

Code cleanup.

Improved modulus solving.

Trap "x%0".  Simplify "x%inf".

Fix fraction list display of -0.

Change for better simplification.

Fix for division by roots of fractions.

Log message:
Update mathomatic to 11.6d.

Changes:

Some more improvement to simplification.

Displayed floating point precision reduced to 12 digits.

Allow typing just "e#" or "pi" on the command line, to give the
values for each.

Changed simplify command to prefer (1/constant)^n instead of 1/(constant^n).
It produces more efficient code and solves a problem.

Improved "code integer" command by allowing integer powers.

Improved eliminate command by trying next equation if solve fails.

"list export" now produces 100% Maxima compatible equations.

Changed "SILENT" compile time define to also remove all debugging code.

Log message:
Update mathomatic to 11.6c.

Changes:
- Some more touch-ups to solve routine.
- Changed uf_repeat() to skip expanding if the expression would be too big.
  This allows Mathomatic to work with huge exponents.
- Turned on "preserve_roots" option by default.
- Improved sum and product commands.  Allow counting down.
- Improved solve routine and removed display of useless messages.
- Added a fix to the limit command.
- Moved "source.txt" into "README.txt".
- Added code to simplify (inf+a) to (inf) generally.
- Fixed minor bug in calculate command.
- Minor fixes to elim_k().
- Improved limit command.
- Made all recursive functions in the source code static.
  Most functions never used globally defined as static.
- Improvement in command argument parsing.
- Added extrema command.
- Improved output of roots command.
- Fixed minor bug caused by "preserve_roots" option.
- Made file "am.htm" valid HTML.
- Simplification improved.

Log message:
Update mathomatic 11.6.

Changes:
  - Many minor improvements made, none of which are worth mentioning by
    themselves.
  - Fixed all message strings with a variable listed in them.
  - Added iteration option to calculate command.
  - Trimmed set command of fat.  Unnecessary messages removed.
  - Removed all occurrences of "usage_flag".
  - Usage info is now displayed everytime a command returns with error.
  - Allow parsing of hexadecimal constants.  Preceed hex numbers with
    "0x".
  - There may be parsing bugs.  Systems using older versions of the GNU
    libraries (specifically strtod(3)) will not allow hexadecimal input.
  - Added limit command.
  - Trapped 0^(negative number).  It previously produced junk.
  - Allow solve routine to produce infinity as an answer.
  - Some commenting and fixing done to solve routine.

Log message:
Update mathomatic to 11.5c.

Changes:
  - Added loading of $HOME/.mathomaticrc on startup.
    Set options go there.
  - Added undocumented switch "-t" which sets test mode.
    Only used with "make test".
  - Wrote and added "matho-pascal" program to primes directory.
  - Allow "=" in set command.
  - Improved uf_repeat() and modulus simplification.

Log message:
Update mathomatic to 11.5b.

Changes:
  - Made HTML mode ("mathomatic -h") not use readline.
  - Added "set true_modulus" option.
  - Improved output of roots command.
  - Code cleanup.

Log message:
Update mathomatic to 11.5.

Changes:
  - Using "memmove()" instead of deprecated "bcopy()".
  - Added "tests/tutor.in", which is an incomplete Mathomatic tutor.
  - Many improvements to scripts in the tests directory.
  - Removed "calculate factor" option.
  - Code cleanup.
  - Added more modulus simplification.
  - Simplify ((a%n)*integer+b)%n to (a*integer+b)%n generally and completely.
  - real^complex and complex^complex are now approximated.

Log message:
Update mathomatic to 11.4d.

Changes:
  - Removed obsolete short variable name code and bumped up "MAX_VARS" \ 
to 500.
  - Fixed problem with conflicting names and code for "cpow()" and \ 
"cexp()".
    Renamed to "complex_pow()" and "complex_exp()".

Log message:
Update mathomatic to 11.4c.

Changes:
  - Code cleanup.  Polynomial division routine is now very easy to use.
  - Renamed "WINDOWS" define to "CYGWIN".
  - Added "set preserve_roots" option.
  - Added modulus solving.

Log message:
Update mathomatic to 11.4b.

Changes:
  - Added "code integer" command, which outputs working C code with integer
   variables.
  - Changed makefile to use libncurses instead of libcurses.
  - Added more simplification rules for modulus.
