* doc2tex.c -- program to convert Gnuplot .DOC format to LaTeX document

* Also will work for VMS .HLP files.

* Modified by Russell Lang from hlp2ms.c by Thomas Williams

* Extended by David Kotz to support quotes ("), backquotes, tables.

* Extended by Jens Emmerich to handle '_', '---', paired single

* quotes. Changed "-handling. Added pre/post-verbatim hooks.

* usage: doc2tex [file.doc [file.tex]]

* where file.doc is a Gnuplot .DOC file, and file.tex will be an

* article document suitable for printing with LaTeX.

* typical usage for GNUPLOT:

* doc2tex gnuplot.doc gnuplot.tex

* latex gnuplot.tex ; latex gnuplot.tex
