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