plus a couple of minor changes.. Some highlights of the new stuff that was not in the old version: - remote access support.. full checkout/commit/log/etc.. - much improved dead file support.. - speed improvements - better $CVSROOT handling - $Name$ support - support for a "cvsadmin" group to cut down rampant use of "cvs admin -o" - safer setuid/setgid support - many bugs fixed.. :-) - probably some new ones.. :-( - more that I cannot remember offhand..

# Usage is:
|
|
#
|
|
# cl-merge [-i] file ...
|
|
#
|
|
# With -i, it works in place (backups put in a ~ file). Otherwise the
|
|
# merged ChangeLog is printed to stdout.
|
|
|
|
# Please report any bugs to me. I wrote this yesterday, so there are no
|
|
# guarantees about its performance. I recommend checking its output
|
|
# carefully. If you do send a bug report, please include the failing
|
|
# ChangeLog, so I can include it in my test suite.
