I almost feel stupid asking this, but... are there any good sample .po files out there? I have been reading the GNU gettext manual and while it specifies the general structure it doesn't go into as much detail as I would like. Plus I would really like an actual fleshed out .po file that utilizes its more advanced functions (like msgctxt, #| msgctxt etc) so that I can run tests against it.
Any tips on where to find something like this?
Look for some big open-source project, like openSUSE (Linux distro) - po files are available on http://svn.opensuse.org/svn/opensuse-i18n/trunk/, I'm sure you'll find there every possible function used.
