This the famous fig program, ported to X11. I have ported version 1.4
with patches for LaTeX line drawing by Frank Schmuck of Cornell.
I only added code to it, which means this is a derivative work, so you
have to stick to the terms of redistribution of the SunView version.
The copyright belongs to Supoj Sutanthavibul, but the source code for
fig (the SunView only version) has been freely available to everyone
for a long time. In particular, it has been available for ftp from
sally.utexas.edu and is also stored in the Sun-Spots archive.
Therefore, I presume that you may also freely redistribute xfig source
code and you should *at least* not remove the copyright notice and not
try to make money selling it. Naturally, everything is provided as is
and the user bears all risks of using this software. Disclaimer: I am
not a lawyer so none of what I say may have any legal weight.
I have chosen to retain compatibility with the SunView version, mainly
for sanity; so that I know I haven't changed the modus operandi of the
program. You can compile for SunView simply by editing two lines in
the Makefile. You may have to change the paths a little.
Updating the ruler arrows slows down xfig noticeably. You might want to
optimize the code or make this feature an command line option.
I know there are things that aren't quite right with the program, I
don't have time to fix them properly now. There are some quirks with
the behaviour of xfig. Lots of error returns that should be checked
are not.
I will gratefully receive bug reports and tune ups but I'm not
interested in taking up maintenance in the long run. (I have to finish
a thesis.) In particular reports of little-endian machine versions and
weird machines (not Sun or Vax) are interesting to me.
If you send me bug reports they will probably sit in my mailbox until I
have the time to install them locally. Then it may be some time before
I post a new version. So it will be best if you also posted your fixes
to some public place. As for coordinating and merging fixes, well that
will have to happen by anarchy unless somebody volunteers to be the
grundge.
Please keep the history and version numbers up to date.
The fig2latex translator and friends are part of the transfig package
from Cornell and at the time of writing, were available by ftp from
svax.cs.cornell.edu.
