	Since there has much talk of AmigaDOS 2.0, let me hit you all with
this. 

	AmigaDOS 2.0 allows you to get notified when a certain file is mod-
ified. Unfortunately, that only seems to be the case when a file is actually
changed. So I guess if you were watching a directory, you would find out
about everytime a file beneath it were affected. This only works for writing
the file's contents. It doesn't work for reading and executing it. Are my
assumptions correct? UNIX filesystem maintains a date stamp that is updated
everytime a file is accessed. AmigaDOS does not. So if there was some way
to tell what file had been accessed - there would be no way to determine
directly from the filesystem the frequency. The program would have to main-
tain its own datestamp database. 

	I'm trying to see the light at the end of the tunnel on this. Anyone
else have any input on this?
