# This script normalizes the GlobalPhone German dictionary. It removes the
# braces that separate word & pronunciation; removes the 'M_' marker from each
# phone; (optionally) puts '-' between the letters of acronyms; and
# (optionally) tags the phones with language ('GE') marker. It also converts
# the words to UTF8 and lowercases everything, either of which can be diabled
# with command line switches.
