This is incorrect. $Rev$ is a shortcut for $LastChangedRevision$, which
will expand to the revision number in which the file changed. On checkout
the value should not change, though there was bug recently where it got
expanded to the revision that was checked out). Until a new keyword is
implemented to give you the last checked out/updated revision number, you
have to either have your script call 'svnversion' or parse the output of
'svn info wc-root'. If you are working on an exported version this won't
work. Instead you can create a tag and export that, then parse $HeadURL$
for version information you store in the name of the tag. Tedious &
prone to errors, yes.

See the section on svn:keywords in "Special Properties" here:

http://svnbook.red-bean.com/

or, from 'svn help propset':

 svn:keywords - Keywords to be expanded. Valid keywords are:
   URL, HeadURL - The URL for the head version of the object.
   Author, LastChangedBy - The last person to modify the file.
   Date, LastChangedDate - The date/time the object was last modified.
   Rev, LastChangedRevision - The last revision the object changed.
   Id - A compressed summary of the previous
                                4 keywords.

I remember seeing a patch sent to the list to allow 'custom' keywords, but
you'd have to search the list/issues for more info on that.
