For the purpose of my e-mail, I am referring to
"symbolic/mnemonic name/etc" as a 'label' for
continuity.
If a label was merely a name for a revision, then why
would it be checked out when you check out the entire
repository? That simply doesn't make sense. It would
make sense if it were a branch (like it is now), but
it would not if a label were truly what we have been
talking about.
For example:
$ svn co $BASE_URL -r 592
$ svnversion .
592
$ svn label MY_PROJECT_RC_1
$ svn commit
...
$ cd $SOME_OTHER_DIR
# co the head of the repo
$ svn co $BASE_URL
$ svnversion .
2000
BRM
P.S. Personally I think labels would likely be added
retrospectively like the above. But probably more
likely to be done like the following:
$ svn co $BASE_URL
$ svn label MY_PROJECT_RC_1
$ svn commit
