# This rather broken little bit of hackery will take a TextMate theme and 
# "normalize" it by scanning the settings array and eliminating duplicates. It 
# preserves order, but the latter setting of any duplicate (or triplicate, etc) 
# will be the one that survives in the written file. 
# 
# The UUID is changed and the name has "(processed)" appended to it
#
# It is a crap script.  It does exactly what I need.
