# This script normalizes the GlobalPhone Spanish dictionary. It removes the
# braces that separate word & pronunciation; removes the 'M_' marker from each
# phone; and (optionally) tags the phones with language ('SP') marker. It also
# converts the words to UTF8 and lowercases everything, either of which can be
# diabled with command line switches.
# *No special treatment for acronyms since some words are already capitalized.
