+Run this script from the root of the repository to update all translations from
+transifex.
+It will do the following automatically:
+
+- fetch all translations using the tx tool
+- post-process them into valid and committable format
+ - remove invalid control characters
+ - remove location tags (makes diffs less noisy)
+
+TODO:
+- auto-add new translations to the build system according to the translation process
+- remove 'unfinished' translation items
