This script will configure your system to only update Contents files
when "apt-file update" is run. This is done by installing two config
files for APT.
To do this, please run the following as root:
$0 --install
NB: Depending on your system and your APT configuration, you may have
to tweak the resulting /etc/apt/apt-file.conf to ensure you do not
fetch some resources twice (it uses a blacklist).
If you want to undo it, then as root run:
$0 --uninstall
CAVEAT: During --uninstall will simply remove the files/directories
created by this script *WITHOUT ANY BACKUP*. Manual changes to
e.g. /etc/apt/apt-file.conf *WILL BE LOST*.
