# File: roffcmds.icn
#
# Subject: Program to list roff commands and macros
#
# Author: Ralph E. Griswold
#
# Date: June 10, 1988
#
###########################################################################
#
# This progam processes standard input and writes a tabulation of
# nroff/troff commands and defined strings to standard output.
#
# Limitations:
#
# This program only recognizes commands that appear at the beginning of
# lines and does not attempt to unravel conditional constructions.
# Similarly, defined strings buried in disguised form in definitions are
# not recognized.
#
# Reference:
#
# Nroff/Troff User's Manual, Joseph F. Ossana, Bell Laboratories,
# Murray Hill, New Jersey. October 11, 1976.
