  /**
   \brief
   Singleton to return SVN global revision

   This can be used to get the SVN global revision number, since
   the usual keyword replacement in SVN will not fill that information
   in anyplace.  The revision number is determined using the 
   svnversion utility at the time configure is run, IF you are
    working from the SVN repository.
   If you are not working from the repository (eg you use a tarball
   distribution), then the value was filled at the time the release
   manager built the distribution.

   NB. If you work from SVN, and you update your local revision
   but do not re-run configure, then the SVN global revision number
   in this file will not be updated.  Too bad for you.  In any 
   case, it is a good idea to reconfigure when you update your
   local copy of the repository anyway.
