/*
	NOTE:

	xgettext does not officially support Go syntax, however, you can generate a valid .pot file by forcing
	xgettest to use the C++ syntax:

	% xgettext -d example -s gettext_test.go -o example.pot -L c++ -i --keyword=NGettext:1,2 --keyword=Gettext

	This will generate a example.pot file.

	After translating the .pot file, you must generate .po and .mo files.

	Remember to set the UTF-8 charset.

	% msginit -l es_MX -o example.po -i example.pot
	% msgfmt -c -v -o example.mo example.po

	And finally, move the .mo file to an appropriate location.

	% mv example.mo examples/es_MX.utf8/LC_MESSAGES/example.mo
