# rcsfreeze - assign a symbolic revision number to a configuration of RCS files

|
# 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
