# Aap recipe for Portuguese Vim spell files.
#
# Based on a shell script by Leonardo Fontenelle.
# His remarks:
#
# Makes a Vim pt dictionary from OpenOffice.org's pt_BR and pt_PT.
#
# AFAIK, will have to update the script every time a new dictionary is 
# released for pt_BR. I asked the maintainer to update OOo's FTP site,
# but it didn't happen yet. As for the pt_PT dictionary, they won't be
# in OOo's FTP site for some time, because the Portuguese OOo project
# decided to adapt the pt_BR dictionary, which is much more extensive.
# I picked the Natura project unofficial dictionary, because it has been
# developed by a team with linguists, and for a longer time. At least the
# pt_PT dictionary has a "latest" file to make our lives easier.


# Use a freshly compiled Vim if it exists.
