Say I want to display the subversion release number in the footer of
each page in order to track what version of a site I’m looking at.
I know subversion has a substitution keyword (LastChangedRevision)
that inserts the last known revision in which that file .changed.
So, if I stick $LastChangedRevision$ into
views/layouts/application.rhtml, it’ll show the last time that file
was changed, not the current version of the repository. W hich isn’t
quite what I want. Any ideas?
