+.SH NAME
+rcsfreeze \- freeze a configuration of sources checked in under RCS
+.SH SYNOPSIS
+.B rcsfreeze
+.RI [ "name" ]
+.SH DESCRIPTION
+.B rcsfreeze
+assigns a symbolic revision
+number to a set of \*r files that form a valid configuration.
+.PP
+The idea is to run
+.B rcsfreeze
+each time a new version is checked
+in.  A unique symbolic name (\c
+.BI C_ number,
+where
+.I number
+is increased each time
+.B rcsfreeze
+is run) is then assigned to the most
+recent revision of each \*r file of the main trunk.
+.PP
+An optional
+.I name
+argument to
+.B rcsfreeze
+gives a symbolic name to the configuration.
+The unique identifier is still generated
+and is listed in the log file but it will not appear as
+part of the symbolic revision name in the actual \*r files.
+.PP
+A log message is requested from the user for future reference.
+.PP
+The shell script works only on all \*r files at one time.
+All changed files must be checked in already.
+Run
+.IR rcsclean (1)
+first and see whether any sources remain in the current directory.
+.SH FILES
+.TP
+.B RCS/.rcsfreeze.ver
+version number
+.TP
+.B RCS/.rcsfreeze.log
+log messages, most recent first
+.SH AUTHOR
+Stephan v. Bechtolsheim
+.SH "SEE ALSO"
+co(1), rcs(1), rcsclean(1), rlog(1)
+.SH BUGS
+.B rcsfreeze
+does not check whether any sources are checked out and modified.
+.PP
+Although both source file names and RCS file names are accepted,
+they are not paired as usual with RCS commands.
+.PP
+Error checking is rudimentary.
+.PP
+.B rcsfreeze
+is just an optional example shell script, and should not be taken too seriously.
+See \s-1CVS\s0 for a more complete solution.

+#       The idea is to run rcsfreeze each time a new version is checked
+#       in. A unique symbolic revision number (C_[number], where number
+#       is increased each time rcsfreeze is run) is then assigned to the most
+#       recent revision of each RCS file of the main trunk.
+#
+#       If the command is invoked with an argument, then this
+#       argument is used as the symbolic name to freeze a configuration.
+#       The unique identifier is still generated
+#       and is listed in the log file but it will not appear as
+#       part of the symbolic revision name in the actual RCS file.
+#
+#       A log message is requested from the user which is saved for future
+#       references.
+#
+#       The shell script works only on all RCS files at one time.
+#       It is important that all changed files are checked in (there are
+#       no precautions against any error in this respect).
