# task-$DESKTOP-desktop - core package set for desktop $DESKTOP
# task-$LANGUAGE - core package set for language $LANGUAGE

# task-$LANGUAGE-$DESKTOP-desktop - i18n packages for $DESKTOP, $LANGUAGE
# task-$FOO - package set for $FOO (mail-server, laptop, etc.)

# * languages can be 1, 2 or 3 words (eg. english, brazilian-portuguese, south-african-english)
# * non-desktop tasks can be 1 or 2 words (e.g. laptop, file-server)
#
# Need to parse debian-tasks.desc to work out what each type is
