Bellhop Mac

Say hello to Bellhop, an easy way to write Mac OS X system services. Have an idea for a service, but don't want to fire up Xcode? No problem! Just write your service in one of the supported scripting languages and let Bellhop do the heavy lifting.
How does Bellhop work?

Bellhop uses a single-window interface that allows you to organize, edit and configure your services in one place. Publishing a new service is simply a matter of writing the script for your service and configuring some settings.

Behind the scenes, Bellhop updates the necessary system property lists, updates the system-wide Services menu, and automatically activates your script when necessary.
