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 ## version='rcsfreeze (GNU RCS) 5.9.0 Copyright (C) 2010-2013 Thien-Thi Nguyen Copyright (C) 1990-1995 Paul Eggert License GPLv3+; GNU GPL version 3 or later <http://gnu.org/licenses/gpl.html> This is free software: you are free to change and redistribute it.
