+ *
+ * `xgettext --no-wrap [-j] [-o file]`
+ *
+ * Where -j is used to join an existing catalague.
+ * -o file is the output file.
+ *
+ * Basic usage:
+ *
+ * * mc::load("messages.po|messages.ini");
+ * * mc::plugin_init($plugin,$plugin->getFile());
+ * * mc::_("string to translate\n")
+ * * mc::_("string to translate %1% %2%\n",$arg1,$arg2)
