Test XML-RPC code

WordPress can either be used via the web interface or through the official
WordPress apps for mobile devices. WordPress uses XML-RPC internally to
communicate between the app and the WordPress admin. Make sure therefore
that when developing functionality that is linked to functionality available
in the mobile app that it also works over XML-RPC.

Translating the plugin

Language packs will be generated for the plugin once translations for a
language are 100% filled in and approved.

See https://translate.wordpress.org/projects/wp-plugins/tiny-compress-images.

For development you may create .po and .mo files for a each language. The .mo
files can be created with gettext.
Install gettext and generate the .mo language file do the following:

1. Install gettext for example run brew install gettext.
2. Add a link msgfmt ln -s /usr/local/Cellar/gettext/0.19.7/bin/msgfmt ~/.bin.
3. Generate the .mo files bin/format-language-files.

When finished modifying, you can upload the changes to the SVN trunk. Within
roughly 15 minutes WordPress will be updated and allow to add missing
translations before publishing the new plugin release.
