Magnet is a commercial package from No Hands Software. You can specify
filter qualities for Mac files, and an action to take on those files. Magnet will
then collect all matching files and execute the action. Someone at No Hands
must have stumbled across the word agent and said, "Hey, this looks cool,
let's call this file utility an agent!" Well, that still didn't make it smart. The
best example of this is when a reviewer spelled the name of a folder
incorrectly. Magnet said to itself, "Gee, I can't find this folder called
'Applications' so I guess I'll just throw all these files in the Trash." Woops.
