define HELP
This Makefile assists in handling i18n related tasks during development. Files
that need to be checked into source control are put into the locales/ directory.
They are
locales/$(POT_NAME) - the POT file generated by 'make update-pot'
locales/$$LANG.po - the translations for $$LANG
Only the $$LANG.po files should be edited manually; this is usually done by
translators.
You can use the following targets:
i18n: refresh all the files in locales/ and recompile resources
update-pot: extract strings and update locales/$(POT_NAME)
locales/LANG.po: create translations for LANG
msgfmt: compile the translations into Java classes; this step is
needed to make translations available to the Clojure code
and produces Java class files in resources/
endef
# @todo lutter 2015-04-20: for projects that use libraries with their own
# translation, we need to combine all their translations into one big po
# file and then run msgfmt over that so that we only have to deal with one
# resource bundle
