Symbolic revision names in dump files
I've been working on keeping an SVN repo in sync with the BitKeeper
Linux Kernel CVS repo.
I've modified cvs2svn (a lot, to the point it is now just bkcvs2svn) to
do incremental updates from the CVS repo in the form of dumps that I
load into the svn repo on a regular basis.
I had one hurdle to overcome, which was I needed to track the repo's
revision numbers for tags. For example, if an incremental run created a
new tag from the head (the tags are always just copies of HEAD in
bkcvs), I had to know the current revision so that the copyfrom-rev in
the dump file was correct.
That seems less than adequate, since generally revision numbers in the
dumpfile could otherwise be ignored. It would be nice of the svnadmin
load parser could accept symbolic revisions, or atleast just HEAD.
Anyone else thought about or approached this?

I'm still not sure how revision properties help me in this case. It's
not like I know what revs will become a tag ahead of time.

Giving 'alias' names to revisions seems like a perfect excuse to use a
revision property.
The only question is -- do make it a "standard" property, like
svn:revision-names? If we do, then it would be nice if svn_repos.h
(svn_fs.h?) had a utility function to search all revision proplists
and look for revision(s) which match the propval.
Otherwise, I guess you could do this from a python script using the
swig bindings... kinda messy either way, though.
