Hello all,

I know I can use {{{modification-time(...,t)}}} say to get the revision
control system information about when the repository was last
modified.  However, I would like to have other information (e.g. the
mercurial id).  More importantly, I would like this information to
appear on my beamer export title slide.

I have tried

#+date: \copyright {{{time(%Y)}}}, version src_shell{hg id --num}

for instance but babel blocks are not executed for these
lines.  Putting this text in a macro doesn't help either.

Any suggestions?

Thanks,
eric
