I like it.

Let's have some cross-project compatibility (to avoid confusion or
subtle typos when using the same option already in use elsewhere). Many
GNU projects already have the following configure options:
--with-packager String identifying the packager of this software
--with-packager-version Packager-specific version information
--with-packager-bug-reports
Packager info for bug reports (URL/e-mail/...)
and in fact, they get that straight out of gnulib, via the version-etc
module (unfortunately LGPLv3+ at the moment) - let me see if I can get
that improved, so we can reap the benefits of shared code, before I
review a slightly different implementation for libvirt. But part of the
issue is that the current version-etc module, in addition to providing
the nice .m4 file for defining additional PACKAGER variables in the
source code, also provides the version_etc() function which is hardcoded
to output a GPLv3+ version string (oops - why is the module LGPLv3+ if
it outputs GPLv3+?).
Gnulib already has version-etc-fsf separate from version-etc for easy
exclusion of an FSF copyright holder, so what is still missing is an
easy way to override the default license output when using
version_etc(). Maybe by moving the default GPLv3+ out of version-etc.c
and into version-etc-fsf.c.
