A Little Brother for DEVONagent
If you don't need the full power of DEVONagent Pro or even just DEVONagent Express we have good news for you: We have submitted DEVONagent Lite to the Mac App Store today. It's small, it's convenient, and it's free.
Note: DEVONagent Lite is not yet available in the Mac App Store. It first has to pass Apple's review, of course.
