# This script normalizes the GlobalPhone Portuguese dictionary. It capitalizes 
# the words; (optionally) tags the phones with language ('PO') marker; and 
# (optionally) puts word-begin and -end markers or word-boundary markers on 
# phones.
# *No special treatment for acronyms since some words are already capitalized.
