Re: [libvirt] [PATCH v3 03/22] build-aux: rewrite po file minimizer in Python

As part of an goal to eliminate Perl from libvirt build tools, rewrite the minimize-po.pl tool in Python. This was a straight conversion, manually going line-by-line to change the syntax from Perl to Python. Thus the overall structure of the file and approach is the same. Signed-off-by: Daniel P.
