Ok, that is what I expected.

Seems a bit low level to me.  I am using this keyword expander script
in three projects, two using monotone, and one using prcs.  Part of
the configuration of the keyword expander is how the underlying
version control system is dealing with keywords (prcs is very good
with keywords, but only supports local operations).  I am a bit afraid
that adding such low level stuff is going to complicate the
implementation of the keyword expander and perhaps break the
interoperability with other version control systems.

The benefit of the keyword expander is that building releases for any
of the three packages is done in a consistent way, and integration of
those packages becomes trivial (I hope, still have to work on it).
The keywords of those packages, the release label ao, have consistent
values representing the fact if the package was distributed as part of
the integrated whole or as an independent entity.  Not sure if this
explanation is clear, but I hope you get it.  In the end, I will hope
to do my release management with the same set of perl scripts for
several projects, some composed of others, some being atomic units.

Thanks ofr your replies, I will give m7 a look and see if I can use it.
