Hi Ernesto,
hi Robin,

thanks for your replies.

The thing I like most with your solution is that svnversion provides a
modify flag, so I can see whether all changes have been cheched in. Great.

A little drawback is that all files under the current path are used to
determine the version. If theres a file in the path which is not part
of the document changes to this file will also change the revision of
the document. But I think this can be easily prevented by placing
every document into an own directory.

What do you think of using:

\def\SVNVERSION{svnversion -n > svnversion.tex}

\ifeof18
    \installprogram{\SVNVERSION}%
\else
    \executesystemcommand{\SVNVERSION}%
\fi

Kind regards,
Markus

This is not true. The complete name of $Rev§$ is
$LastChangedRevision$. It's the revision of the last change to this file.

There can be no useful global last revision number, because
it always depends on the used URL.
