GnuPG version info from GPGME?

[Robert J. Hansen]

I'm working on a command-line application to migrate profiles not just
between machines, but versions of GnuPG.  E.g., 1.4 on machine A -> 2.1
on machine B, or vice-versa.  For this, I need a way to discover which
version of GnuPG is currently installed.  A quick look through the GPGME
manual doesn't reveal anything.

Have I just overlooked it, or do I really need to launch gpg --version
and parse the output?
