Usage is like:

seki-strombrg> ./kill-duplicate-processes 
Usage: [-v n] [-d] ./kill-duplicate-processes command user1 user2 ... usern
The effect is to kill all but the most recent instance of "command" for the given list of users
command is currently searched only by substring, not regex
The higher n is on -v, the more verbose the program will run.  Valid values so far are 0, 1 and 2
-d says to only do a dry run: report what would have been killed and left, but don't kill anything
