Embedding tag name in files

[Richard Curnow <rc...@rc0.org.uk>]

I use the following behaviour with CVS, and was wondering how I can
achieve it with subversion.

With CVS, I embed $Name$ in the source somewhere, e.g. as 

static char *version = "$Name";

Now when I release the code, I tag the repository

cvs rtag VX_Y project

Then when I do 'cvs export -r VX_Y project' to get the source tree from
which the tarball is created, the $Name$ string is replaced by VX_Y.
Inside the program, I can process this to report the program version to
service the --version switch etc.

I can't see an obvious way to do the equivalent in subversion.  How do
people embed released s/w versions inside the program source?  (Other
than the obvious hand editing a file, committing that then forking the
tagged version of the trunk - I'd like to avoid this kind of thing.)

Cheers

the $URL$ keyword seems like the subversion equivalent of this 
functionality.
