+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 :)
