+### Meta data of Plugins/Themes
+
+You may use the `processPot` callback to control which meta data is automatically added to the POT file. This may be useful if you don't want Author or Plugin/Theme names and urls to be translatable.
+
+```js
+grunt.initConfig({
+    makepot: {
+        target: {
+            options: {
+                processPot: function( pot ) {
+                    var translation, excluded_meta = [
+                        'Plugin Name of the plugin/theme',
+                        'Plugin URI of the plugin/theme',
+                        'Author of the plugin/theme',
+                        'Author URI of the plugin/theme'
+                    ];
+                    for ( translation in pot.translations[''] ) {
+                        if ( typeof pot.translations[''][translation].comments.extracted != 'undefined' ) {
+                            if ( excluded_meta.indexOf( pot.translations[''][translation].comments.extracted ) >= 0 ) {
+                                delete pot.translations[''][translation];
+                                console.log( 'Excluded meta: ' + pot.translations[''][translation].comments.extracted );
+                            }
+                        }
+                    }
+                    return pot;
+                },
+                type: 'wp-plugin'
+            }
+        }
+    }
+});
+```
+

+
+```
+Plugin Name of the plugin/theme

+Plugin URI of the plugin/theme
+Theme URI of the plugin/theme
+Description of the plugin/theme
+Author of the plugin/theme
