What is the easiest way to determine the HEAD revision number?

[Garrick Olson <Ga...@Aceva.com>]

Some code I am writing needs to determine the latest revision number in
the repository.

I am currently doing this by issuing a command like:

svn log --non-interactive --xml -r HEAD:COMMITTED mywc

This may return (many) multiple log entries, but the first entry should
contain the latest revision.

Will this command work in *all* situations? (No situations where is
might return no entries?)
Is there a more direct or efficient way to do this?

Is this not what you want?

NOTE: this is the highest revision for this WC path, which is, I think, what you 
are getting from your 'svn log...' call as well.  Neither will give the highest 
(i.e. most recent) commit to the _entire_ repository.  For that, you should use:
