branch number that is assigned. This is specifically to support the
local commit feature of cvsup. If one sets $CVS_LOCAL_BRANCH_NUM to
(say) 1000 then branches the local repository, the revision numbers will
look like 1.66.1000.xx. This is almost a dead-set certainty that there
will be no conflicts with version numbers. :-)
(This needs to be something more than an option to 'cvs tag' or 'cvs rtag'
as various parts of cvs "know" how to automatically branch files (eg: cvs
add). Trying to remember state is getting "Too Hard (TM)")
