#
# This script takes the output of 'gettocx' and creates
# table of contents entries for a given section.
# The input is of the form:
#	name(section): description
#
# The output is of the form:
#	.xx "name" "description"
#
# The 'grep' and the first 3 lines of the 'sed' script 
# move the intro section to the beginning of the file.
# The rest of the 'sed' script removes the colon between
# the name and description (line 4), removes the period
# at the end of the line (line 5), removes the section
# numbers (line 6), puts quotes around the name and description
# (lines 6, 7), inserts the '.xx' macro at the beginning of
# each line (line 7), and removes and lines with a null
# name or description (line 8).
