+ * doc2rnh.c -- program to convert Gnuplot .DOC format to
+ * Digital Standard Runoff for VMS HELP files
+ * (gnuplot.doc, including the terminal documentation
+ * is no longer formated for VMS HELP by default)
+ *
+ * From hlp2ms by Thomas Williams
+ *
+ * Modified by Russell Lang, 2nd October 1989
+ * to make vms help level 1 and 2 create the same ms section level.
+ *
+ * Modified to become doc2ms by David Kotz (David.Kotz@Dartmouth.edu) 12/89
+ * Added table and backquote support.
+ *
+ * Adapted from doc2ms.c (the unix 'runoff' text-processor)
+ * by Lucas Hart 3/97
+ *
+ * right margin is adjusted two spaces for each level to compensate
+ * for the indentation by VMS HELP
+ *
+ * the page width can be adjusted by changing the value of DSR_RM
+ * usage: $ MCR []doc2rnh gnuplot.doc gnuplot.rnh
+ * $ RUNOFF gnuplot.rnh
