fig2ps is a perl script which converts xfig files to postscript or PDF, processing text with LaTeX. It's primary aim is to produce documents (such as articles) with a high quality, in which the pictures are seamlessly integrated with the text (notably, the font in the figures is exactly the same as in the text).
The way to use it is simple : draw your picture with xfig,
marking all text as special (there is one way to force this, look at
the manual page). Then, invoke
fig2ps on your xfig file. Then, you can integrate
the picture in a LaTeX document by simply saying, for instance,
fig2ps manual page
