Subject: get execution name of program

Either $0 or __FILE__ will return a filename to give context for how a
Ruby program is executed, but I have yet to figure out how to get the
command used to execute it.  Specifically, I want the command without
options.  If a program is executed using an alias from within a Unix
shell, for instance, I want the alias name.

Example:

    > alias foo=3D'/home/username/bin/foo.rb'

What would I use to get a return value of "foo"?
