Cocoa Frameworks for Assistive Applications. PFEventTaps Frameworks has been maintained over a period of many years, and they have demonstrated their power and reliability in PFiddlesoft’s popular developer utilities as well as major commercial third-party applications.

Software testing tools, network administration tools, troubleshooting tools, plug-ins for applications that don't have a plug-in architecture, and remote control applications are only some of the possibilities.
