# Aap recipe for German Vim spell files.
#
# Since there is a big discussion about whether to use the old or the new
# spelling rules, both have been included.
#    "de": all possible words allowed
# "de_de": old and new German spelling
# "de_19": old German spelling
# "de_20": new German spelling
# "de_AT": Austrian spelling
# "de_CH": Swiss spelling

# Use a freshly compiled Vim if it exists.
