! 39: * doc2tex.c -- program to convert Gnuplot .DOC format to LaTeX document
! 40: * Also will work for VMS .HLP files.
! 41: * Modified by Russell Lang from hlp2ms.c by Thomas Williams
! 42: * Extended by David Kotz to support quotes ("), backquotes, tables.
! 43: * Extended by Jens Emmerich to handle '_', '---', paired single
! 44: * quotes. Changed "-handling. Added pre/post-verbatim hooks.
! 45: *
! 46: *
! 47: * usage: doc2tex [file.doc [file.tex]]
! 48: *
! 49: * where file.doc is a Gnuplot .DOC file, and file.tex will be an
! 50: * article document suitable for printing with LaTeX.
! 51: *
! 52: * typical usage for GNUPLOT:
! 53: *
! 54: * doc2tex gnuplot.doc gnuplot.tex
! 55: * latex gnuplot.tex ; latex gnuplot.tex
