Hello,

Not much code this week. Mainly improved few parts (copyout, read and watch
delete parts) and fixed couple of issues related to events. I'm currently
trying to compile and test gamin and working on man pages and documentation.

Hello,<br>
<br>
inotify now supports all the flags and works. There is an issue with<br>
ordering of IN_MOVED_TO and IN_MOVED_FROM events which isn't similar to=
<br>
Linux behaviour. I will be spending this week testing and improving<br>
existing work.<br>
