Well, ARGV is an array of commandline arguments -- it behaves exactly like any
other array. A little testing shows that calling delete from an array will
either return the item asked for, or nil.
So in this case, RAW will be either '-r' or nil, depending on whether there's
a -r in the commandline. Same for MBX and '-m' -- so with no commandline
arguments, RAW and MBX will both be nil.
