You need to install po4a (in Fedora) to test this.
Subject: [PATCH] Allow manual pages and POD files to be translated.
This uses the optional po4a package to split these files into
PO files for translation, and reassemble afterwards.
Note this creates an extra pot file (po-docs/libguestfs-docs.pot).
We don't (yet) combine this with the main po/libguestfs.pot file.
The 'libguestfs-docs.pot' file included in this commit is not the
real thing, just a short cut down snippet for testing. The real
thing is created if you update one of the dependent files and
rebuild.
Note also the dummy ja.po, for testing the principles.

Most of the duplicated pod2man options above can be factored out.
It'd be cleaner still if we could depend on GNU Make,
but in the mean time, you can do something like this:
[untested]
section_number = $$(echo $@|sed 's/.*\.//')
man_name = $$(echo $@|sed 's/\..*//')
pod_to_man = \
$(POD2MAN) -u \
--section $(section_number) \
-c 'Virtualization Support' \
--name $(man_name) \
--release '$(PACKAGE_NAME)-$(PACKAGE_VERSION)'

I don't know off hand.
Ask on the list?

The following is obviously not a problem right now, but something to
think about before we get up to 20 or 40 different translations:
Once there are more translations, all of this duplication may become
cumbersome. Duplicate Makefile.am files, all identical, each in its own
XX/ directory with nothing else... Eventually it'd be nice to avoid that.
I can imagine using a single Makefile.am, and then a separate shell-code
loop over 2-byte country codes, copying each Makefile into a temporary
directory and then invoking make. [TL;DR] it'd be nice not to require
a whole new directory-containing-only-dup'd-Makefile.am for each added
language.
