Comments, AIEE!s and other thoughts about this (Nilsson and I trying to remember what should be done and figure out a good way to do so):
# in the raw repository:
mv 7.3 7.4
# elsewhere:
cvs co Pike/7.4 cd Pike/7.4 cvs tag -R pre73to745split
# back in the reposityory: # remove empty directories
mv 7.4/README.txt 7.4/README mv 7.4/README.cvs.txt 7.4/README.cvs
cp -rp 7.4 7.5
# finish 7.4/CHANGES # clean up 7.5/CHANGES
# (tell someone to update their rsync settings) # rerun CL indexer (since raw changes go unnoticed)
# make dists # make announce
