Changes since 14.3.6:
- Perfected the user interface for the sum, product, and integrate
commands.
- Restored initial full simplify in the limit command for better
results, that was unintentionally removed in version 14.1.0.
- Fixed an endless loop in simplification; results look better, too.
- Added "set save" command, which makes all current session options
permanent, by saving them in "~/.mathomaticrc". "set no save"
removes this file.
- Added "mathomatic -s" option, which stands for secure mode. This is
a run-time option that disallows shelling out and writing files, and
was created for use on public servers that can't use the SECURE
compile-time define.
- Doubled the default maximum mathematical expression size to allow
larger expressions.
- A fatal compilation error when compiling with defines other than
UNIX was fixed.
- Slight improvement made to simplification; results are more simple
and stable.
- The maximum integer that can be factored has been raised from 14 to
15 decimal digits.
- Small fix made to fraction command and "simplify fraction" for
better looking fractions.
- Added a "simplify quickest" command option, which does no
unfactoring nor factoring.
- Made full simplification more efficient and simpler by cutting out
unnecessary loops.
- Improved the divide command and enabled its use in the symbolic math
library. Enabled code and variables commands in library, too.
Currently, library output of these 3 commands can only be gathered
by redirecting to a file.
- Added "set autoselect" and "set auto" options. Use "set no auto" to
always store entered expressions into equation spaces, unless it is
a command.

Non-interactive stdin is always available for reading.
Failing to set the 'stdinOwned' flag meant that you could never read from
stdin which wasn't a terminal. Oops.
commit d0604e797cf194eb025a1784766ebea8cf38ec87
Author: Keith Packard <keithp@keithp.com>
Date: Wed Mar 26 23:21:41 2008 -0700
Allow background nickle to not poll on tty ownership
When stdin is connected to a terminal but nickle is not the foreground
process on that terminal, the io code would poll to wait for ownership to
flip back to nickle so that reads could be performed without generating a
signal. Now, nickle waits until someone actually tries to read from the
terminal before starting to poll. This means that simple background
processing nickle programs will not poll every 100ms.

Remove support for non-SIGIO pipes
Older version of the kernel (before 2001) failed to generate SIGIO on pipes,
so nickle had code to poll instead. I think we can safely remove that code
now.

Avoid having the 'pretty_print' builtin show two error messages.
NamespaceLocate takes a 'complain' boolean that will print out an error
message, but the pretty_print command also raises an exception when it fails
to find the name. Two errors is at least one too many here.

FileGetErrorMessage returns a Value, not a char *
base pkg
-replace hard gnuplot dependency by a MESSAGE as it is only needed
if one really wants to plot a function
-register with desktop-file-utils
bump PKGREVISION
The fix is suboptimal because the y2037 problem remains. It would be
better to either
-extend the "cln" lib for 64-bit integers (but the code is a mess
already) or
-split the time_t into a lower/higher part and convert them seperately,
which is less than elegant.
-add a MESSAGE telling that gnome-vfs or wget are needed to fetch
currency exchange rates automatically, so the (wrong) wget dependency
can be removed from child pkgs
bump PKGREVISION

for nested products to sometimes give wrong result
- corrected fixed output of floating point numbers,
- operations on differential operators like symmetric power work now
- fixed crashes related to coercing power series
- functions returning Void can be traced

* documentation revisions throughout
* patches for Clozure CL throughout
* build Maxima with ECL via build system used for other Lisps
* minor code clean-up throughout
* other improvements and bug fixes
Math::Round is a Perl module. It supplies functions to round numbers,
both positive and negative, in various ways. This may seem like an
odd thing to write a whole module for, but rounding can sometimes be
a little tricky, so I thought some people might find this useful.
Changes since 14.2.7:
12/23/08 - Simplified makefile.
12/26/08 - Fixed rules for simplifying "(x^n)^m" so "misc/john.in" and
others simplify better. Works similar to Maxima now.
12/27/08 - Numeric GCD now properly returns the other parameter, if
either parameter is 0. Renamed "misc/polyroots.c" to
"misc/roots.c" and simplified this example code.
12/30/08 - Added "update" script, which updates the function
prototypes in "cproto.h".
1/1/09 - Optionally factor out the gcd of integer coefficients when
improving readability, for example: 6x+4y becomes 2*((3*x) +
(2*y)). This is now the default.
1/13/09 - Added descriptions of all interesting math scripts in
"tests/README.txt".
1/16/09 - Allow nintegrate and "integrate definite" commands in the
symbolic math library; the bounds are specified in the two
equation spaces following the current equation.
1/18/09 - Made expression and equation entry always consecutively
numbered equation spaces, unless memory is exhausted.
1/19/09 - Made consistent list command output with only one newline
after each equation space.
1/21/09 - Fixed erroneous doubling of parentheses display when solving
and showing steps with "set debug 2".
1/22/09 - Added -b option, to conveniently set bold color mode from
the command line.
1/25/09 - Improved looks of eliminate command by not solving if
equation is already solved.
2/3/09 - Table of contents was added to the Mathomatic User's Manual.
2/5/09 - Added display of any numerical fractions when calculating or
using calculate command; for example, entering "1/2+3/8" now
results in "answer = 0.875 = 7/8".
2/6/09 - Removed erroneous lsqrt() routine obtained from Wikipedia, so
that matho-sumsq works properly now.
2/7/09 - Disable pause command when appropriate (when input not a tty
and for symbolic math library).
2/8/09 - Polished up educational example scripts in "tests" directory.
2/11/09 - Entry of a function now results in "Named functions
currently not implemented" error message.
2/12/09 - Bugfix to matho-primes and added "misc/limits.c".
2/15/09 - The fraction command was fixed to give better results. "set
display2d" flag now no longer affects any results at all, it
only affects 2D output mode.
2/17/09 - Renamed -h (HTML) option to -x, -h is now the help option.
Added -w option to set wide output mode.
3/9/09 - Found the correct formulas for solving the general cubic
equation on Wikipedia, so "tests/cubic.in" always gives
correct answers now.
3/12/09 - Tweak made to simplify result beautifier: factoring priority
only given to real variables now, special constant variables
pi#, e#, and i# have no effect and behave like any constant
now.
3/15/09 - Corrected and improved parse_complex() C function for more
complex number functionality and a bug fix.
3/18/09 - Added "set negate_highest_precedence" option, which allows
the negate operator to be the lower precedence of times and
divide, like it is in Maxima and most other math programs.
3/24/09 - Made "set no autosolve" mode more useful by making it solve
if a solve variable is entered with an equals sign. This
allows easy entry of both single variable expressions (with
no =) and solve variables (with =) while in this mode.
3/27/09 - Selecting equations by entering the equation number was
returning with error if the equation space was empty.
Fixed, you can now select any previously allocated equation
space.
This changes the buildlink3.mk files to use an include guard for the
recursive include. The use of BUILDLINK_DEPTH, BUILDLINK_DEPENDS,
BUILDLINK_PACKAGES and BUILDLINK_ORDER is handled by a single new
variable BUILDLINK_TREE. Each buildlink3.mk file adds a pair of
enter/exit marker, which can be used to reconstruct the tree and
to determine first level includes. Avoiding := for large variables
(BUILDLINK_ORDER) speeds up parse time as += has linear complexity.
The include guard reduces system time by avoiding reading files over and
over again. For complex packages this reduces both %user and %sys time to
half of the former time.

list hasn't been maintained at all and the gain is very limited, so just
get rid of it.
