#
|
||||
# Sccs2rcs is a script to convert an existing SCCS
|
||||
# history into an RCS history without losing any of
|
||||
# the information contained therein.
|
||||
# It has been tested under the following OS's:
|
||||
# SunOS 3.5, 4.0.3, 4.1
|
||||
# Ultrix-32 2.0, 3.1
|
||||
#
|
||||
# Things to note:
|
||||
# + It will NOT delete or alter your ./SCCS history under any circumstances.
|
||||
#
|
||||
# + Run in a directory where ./SCCS exists and where you can
|
||||
# create ./RCS
|
||||
#
|
||||
# + /usr/local/bin is put in front of the default path.
|
||||
# (SCCS under Ultrix is set-uid sccs, bad bad bad, so
|
||||
# /usr/local/bin/sccs here fixes that)
|
||||
#
|
||||
# + Date, time, author, comments, branches, are all preserved.
|
||||
#
|
||||
# + If a command fails somewhere in the middle, it bombs with
|
||||
# a message -- remove what it's done so far and try again.
|
||||
# "rm -rf RCS; sccs unedit `sccs tell`; sccs clean"
|
||||
# There is no recovery and exit is far from graceful.
|
||||
# If a particular module is hanging you up, consider
|
||||
# doing it separately; move it from the current area so that
|
||||
# the next run will have a better chance or working.
|
||||
# Also (for the brave only) you might consider hacking
|
||||
# the s-file for simpler problems: I've successfully changed
|
||||
# the date of a delta to be in sync, then run "sccs admin -z"
|
||||
# on the thing.
|
||||
#
|
||||
# + After everything finishes, ./SCCS will be moved to ./old-SCCS.
|
||||
#
|
||||
# This file may be copied, processed, hacked, mutilated, and
|
||||
# even destroyed as long as you don't tell anyone you wrote it.
