/*
 * roff -a text formatter (based on SOFTWARE TOOLS by Kernighan & Plauger)
 *
 *	This program appears in the BDS C Users Group "Just Like Mom's"
 * disk.  I found no mention of the Author(s) of this program so I guessed
 * the authorship based on the style of comments describing functions, which
 * also appears in "crypt.c" written by kathy bacon and neal somos.
 *
 *
 *
 *   Suggestion for compiling and linking (change to suit).
 *   Note roff1 mentioned twice in clink command.
 *
 *	cc1 roff1.c -e 5000 -o
 *	cc1 roff2.c -e 5000 -o
 *	cc1 ndio.c -o
 *	clink roff1 roff2 roff1 ndio -o roff -s
 *
 *  Note that dio.h used with ndio is not the same as distributed with BDS C
