# eqn2graph -- compile EQN equation descriptions to bitmap images
#
# by Eric S. Raymond <esr@thyrsus.com>, July 2002
#
# In Unixland, the magic is in knowing what to string together...
#
# Take an eqn equation on stdin, emit cropped bitmap on stdout.
# The pic markup should *not* be wrapped in .EQ/.EN, this script will do that.
# A -U option on the command line enables gpic/groff "unsafe" mode.
# A -format FOO option changes the image output format to any format
# supported by convert(1). All other options are passed to convert(1).
# The default format is PNG.
#
# This is separate from pic2graph because pic processing has some weird
# clipping effect on the output, mangling equations that are very wide
# or deep. Besides, this tool can supply its own delimiters.
#
# Requires the groff suite and the ImageMagick tools. Both are open source.
# This code is released to the public domain.
#
# Here are the assumptions behind the option processing:
#
# 1. None of the options of eqn(1) are relevant.
#
# 2. Only the -U option of groff(1) is relevant.
#
# 3. Many options of convert(1) are potentially relevant, (especially
# -density, -interlace, -transparency, -border, and -comment).
#
# Thus, we pass -U to groff(1), and everything else to convert(1).

Usage: ${cmd} [ OPTIONS ] FILE1 FILE2 [ OUTPUT ]
Place difference marks into the new version of a groff/nroff/troff document.
FILE1 and FILE2 are compared, using \`diff', and FILE2 is output with
groff \`.mc' requests added to indicate how it is different from FILE1.
FILE1 Previous version of the groff file. \`-' means standard input.
FILE2 Current version of the groff file. \`-' means standard input.
Either FILE1 or FILE2 can be standard input, but not both.
OUTPUT Copy of FILE2 with \`.mc' commands added.
\`-' means standard output (the default).
OPTIONS:
-a ADDMARK Mark for added groff source lines. Default: \`+'.
-c CHANGEMARK Mark for changed groff source lines. Default: \`|'.
-d DELETEMARK Mark for deleted groff source lines. Default: \`*'.
-D Show the deleted portions from changed and deleted text.
Default delimiting marks: \`[[' .... \`]]'.
-B By default, the deleted texts marked by the \`-D' option end
with an added troff \`.br' command. This option prevents
the added \`.br'.
-M MARK1 MARK2 Change the delimiting marks for the \`-D' option.
-x DIFFCMD Use a different diff(1) command;
one that accepts the \`-Dname' option, such as GNU diff.
--version Print version information on the standard output and exit.

# pic2graph -- compile PIC image descriptions to bitmap images
#
# by Eric S. Raymond <esr@thyrsus.com>, July 2002
# In Unixland, the magic is in knowing what to string together...
#
# Take a pic/eqn diagram on stdin, emit cropped bitmap on stdout.
# The pic markup should *not* be wrapped in .PS/.PE, this script will do that.
# An -unsafe option on the command line enables gpic/groff "unsafe" mode.
# A -format FOO option changes the image output format to any format
# supported by convert(1). An -eqn option changes the eqn delimiters.
# All other options are passed to convert(1). The default format in PNG.
#
# Requires the groff suite and the ImageMagick tools. Both are open source.
# This code is released to the public domain.
#
# Here are the assumptions behind the option processing:
#
# 1. Only the -U option of gpic(1) is relevant. -C doesn't matter because
# we're generating our own .PS/.PE, -[ntcz] are irrelevant because we're
# generating Postscript.
#
# 2. Ditto for groff(1), though it's a longer and more tedious demonstration.
#
# 3. Many options of convert(1) are potentially relevant (especially
# -density, -interlace, -transparency, -border, and -comment).
#
# Thus, we pass -U to gpic and groff, and everything else to convert(1).
#
# We don't have complete option coverage on eqn because this is primarily
# intended as a pic translator; we can live with eqn defaults.
