With the plugin internationalized and next step is to localize it by translating it into another language. There is a number of tools available which can be used to do this. As part of this main series, I am going to cover two of the commonly used tools for translating plugins.
The first is an application called PO Edit which describes itself as the fastest and most convenient way to translate apps and sites with gettext.
The second is the GlotPress plugin for WordPress which works seamlessly with ClassicPress. GlotPress can also be used to translate apps and sites with gettext, but with the added benefit of collaboration.
