One way is to use m4_esyscmd to use a command that is run at autoconf
run time to specify the version.  Autoconf's own configure.ac uses this
method, for example.

If you want changes to the script (or another file) to propagate to
configure automatically, you should set CONFIGURE_DEPENDENCIES in
Makefile.am.

Hope that helps.

Automake still needs changes in order for efficient handling of
fast-changing version strings (as from, e.g., git describe).

Cheers,
Ralf
