3: # 'rcsfreeze' has the purpose of assigning a symbolic revision
4: # number to a set of RCS files, which form a valid configuration.
5: #
6: # The idea is to run rcsfreeze each time a new version is checked
7: # in. A unique symbolic revision number (C_[number], where number
8: # is increased each time rcsfreeze is run) is then assigned to the most
9: # recent revision of each RCS file of the main trunk.
10: #
11: # If the command is invoked with an argument, then this
12: # argument is used as the symbolic name to freeze a configuration.
13: # The unique identifier is still generated
14: # and is listed in the log file but it will not appear as
15: # part of the symbolic revision name in the actual RCS file.
16: #
17: # A log message is requested from the user which is saved for future
18: # references.
19: #
20: # The shell script works only on all RCS files at one time.
21: # It is important that all changed files are checked in (there are
22: # no precautions against any error in this respect).
23: # file names:
24: # {RCS/}rcsfreeze.version for the version number
25: # {RCS/}rscfreeze.log for the log messages, most recent
26: # logmessage first.
