[Unison-hackers] unison and inotify principle

[Benjamin Pierce]

Well, in any case the main implementation work is on the side of the  
external notifier.  What's already there on Unison's side is enough  
to work with.  If someone gets far enough along with the external  
tool to need a more sophisticated interface to Unison, I'll be happy  
to work with them on getting it implemented (especially if it's on  
OSX, where it's easy for me to develop and test).
