WordPress PlugIn Example with Full I18N Internationalization with the standard files POT PO MO

I am sure now days there are many fully internationalized plug ins for Wordpress but this is the first one I have noticed.  I am noting it here along with the plugin archive because I will be writing an internationalized software package soon.

WARNING: Do not download and use with your wordpress installation because I will not be keeping it up to date.  It is only here for study of the internationalization process.

Fun with Plugins makes some assumptions about file names and paths to resources.

It is assumes that your plugin file is located at: YOURBLOG/wp-content/plugins/wp_emarket/wp_emarket.php

It is assumes that your external Javascript file is located at: YOURBLOG/wp-content/plugins/wp_emarket/js/script.js
