# SUMMARY
# extract manual chapter number from comment
# PACKAGE
# sdetools
# SYNOPSIS
# mansect [-|-a|-c|-f|-m|-m|-n|-p|-t|-r|-C] file(s)
# DESCRIPTION
# \fImansect\fR extracts the manual chapter number from
# source file comments in the style of \fInewsrc(1)\fR.
# Typically, \fImansect\fR is integrated with \fImake(1)\fR scripts.
#
# Source files are processed in the indicated order; if no
# files are specified the command produces no output.
#
# The source file language can be specified through a command-line
# option, or can be implied by the filename suffix.
# The expected start-of-comment symbol is shown in the last column.
