Yep, I do the same for the $Date$ property in my DESCRIPTION files. Upon
commit of the file (eg when incrementing the minor version), the date gets
updated automagically. You have to set the Date property, which even has its
own sub-menu if you happen to use the psvn mode under the One True Editor (TM).
Eg for the most recent Rcpp:
Date: $Date: 2011-12-25 14:14:33 -0600 (Sun, 25 Dec 2011) $
and the two $ signs give it away if you know these SVN tricks...

Correct.
The flipside is that you can also add $Revision$, $URL$, ... to each R source
file individually, and they all get their own stamps. I luuuv monotonically
increasing SVN revs, but some git fanboy will surely chime in within the hour
and tell me that I am off my rocker. ;-)

You cannot do something simple
Version: 0.2.3.$Revision$
because the $ will stay there, as discussed above. But you can filter. In
the littler sources we do this with a helper script (which I include below).
That gets us this revision display with an autocreated header file:
edd@max:~$ r --version | head -2
r ('littler') version 0.1.5
svn revision 185 as of 2011-09-17 09:35:56
edd@max:~$
You can use the other magic keywords listed in section "Keyword Substitution"
in Chapter 3: "Advanced Topics" of the SVN book which Brian Ripley already
pointed to.
