Add translate helper in /bin.

To translate a module navigate to the module dir and call ../bin/translate
translate will grab all strings inside function call to the following function names:
 * translate
 * setLabel

In addition any string prefixed with "/*@translate*/" will be grabbed to the file
language/_annotated_strings.php and inserted as a function call to "translate(string)"

Options:
 -x [Module[,Module[,..]] : Excludes translations from all listed modules.

Examples:
 translate
 translate -x Core

Provide alternative Paths:
 You can specify alternate module path with the first argument.
 translate [-x] MODULE_PATH

 e.g.
 translate Auth 	// pwd is prefixed
 translate /absolute/path/to/module/Auth
