 From that section:

"Where's $GlobalRev$?

New users are often confused by how the $Rev$ keyword works. Since the 
repository has a single, globally increasing revision number, many 
people assume that it is this number that is reflected by the $Rev$ 
keyword's value. But $Rev$ expands to show the last revision in which 
the file changed, not the last revision to which it was updated. 
Understanding this clears the confusion, but frustration often 
remains—without the support of a Subversion keyword to do so, how can 
you automatically get the global revision number into your files?

To do this, you need external processing. Subversion ships with a tool 
called svnversion, which was designed for just this purpose. It crawls 
your working copy and generates as output the revision(s) it finds. You 
can use this program, plus some additional tooling, to embed that 
revision information into your files. For more information on 
svnversion, see the section called “svnversion”."


...so we're back at Square One.  :(
