A set of Ruby scripts (mainly polyglot2polylang.rb) to help migrating a WordPress blog to using the Polylang plugin for internationalization, in case you were using the Polyglot or a similar WordPress plugin before for that purpose.
For detailed usage instructions see this article.
Note that this is quick and dirty software I created for one-time usage. Use at your own risk – just don't blame me if it destroys important things in your life ;)
If you extend this for own purposes, your contributions are welcome of course (just send me a merge request).
