+# SUMMARY
+# extract manual page from source file comment
+# PACKAGE
+# sdetools
+# SYNOPSIS
+# srctoman [-|-awk|-c|-f|-mk|-m|-n|-p|-t|-r|-C] [section] file(s)
+# DESCRIPTION
+# \fIsrctoman\fR converts comments in various programming languages to
+# UNIX-style manual pages.
+# The command processes comments in the style of newsrc(1);
+# its standard output is suitable for formatting with nroff(1) or
+# troff(1) using the "-man" macro package.
+# Typically, srctoman is invoked from make(1) 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.
+#
+# .nf
+# .ft C
+ option language comment
+
+ - shell [:#]
+ -awk awk #
+ -c c /*

+ -mk make #
+ -n nroff \\"
+ -p pascal {
+ -t troff \\"
+ -r ratfor #
+ -C any language next argument
+#
+ suffix language comment

+#
+# The required format of comments is discussed below, where SOC
+# stands for the start-of-comment symbol of the language being used.
+# .IP o
+# Start of manual: SOC, followed by `++'.
+# .IP o
+# Section heading: SOC, blank, section name in upper case.
+# .IP o
+# All other text: SOC and subsequent blanks or tabs are removed.
+# Lines that do not start with SOC are left unchanged (useful for
+# inclusion of program text).
+# .IP o
+# End of manual: SOC, followed by `--'.
+# An end-of-comment may follow if the source file language requires this.
+# .PP
+# The following manual sections receive a special treatment:
+# NAME and SUMMARY should appear at the beginning and in
+# this order; DESCRIPTION, DIAGNOSTICS and BUGS will be
+# right-margin adjusted.
+# Other sections may be added freely without confusing srctoman.
+# COMMANDS
+# sh(1), sed(1), expand(1)
+# SEE ALSO
+# newsrc(1)
+# DIAGNOSTICS
+# The program complains if an unknown language is specified
+# of if the language cannot be deduced from the file suffix.
