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 PATH=/usr/gnu/bin:/usr/local/bin:/bin:/usr/bin:/usr/ucb:$PATH export PATH DATE=`date` || exit # Check whether we have an RCS subdirectory, so we can have the right # prefix for our paths. if [ -d RCS ] then RCSDIR=RCS/ else RCSDIR= fi # Version number stuff, log message file VERSIONFILE=${RCSDIR}.rcsfreeze.ver LOGFILE=${RCSDIR}.rcsfreeze.log # Initialize, rcsfreeze never run before in the current directory [ -r $VERSIONFILE ] || { echo 0 >$VERSIONFILE && >>$LOGFILE; } || exit # Get Version number, increase it, write back to file.
