NoRM provides a good tool to monitor disk space. The inventory function
is very good at finding disk hogs, inappropriate files (AVI's, movies,
music, etc). But it's reporting is overkill.

Is it possible to customize NoRM so that we can have it report on a subset
instead of ALL users, ALL files, etc? We would like to customize it's
output to only the top 5 disk hogs, only the top five file extensions
using disk space, things like that.

And it would be nice to find a way to have it automatically run off-hours
at some interval.

Is documentation available on NoRM? Can this be done?
