COMMENT="# this script is part of apt-get-interim, a tool for updating a debian system
# without fast local net connection.
# there are three stages.
# first read in a list of needed packages.
# second download them on any debian system with fast internet connection.
# third install them on the origin debian system
# a bunch of scripts will be generated by apt-get-interim,
# so you simply have to start four scripts at all and everything will be fine :)
