+# Usage: rcsfreeze [symbolic-name]
+#
+#       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).
+#       file names:
+#       {RCS/}.rcsfreeze.ver	version number
+#       {RCS/}.rscfreeze.log	log messages, most recent first
