# Short-Description: apt helper for peer-to-peer downloads of Debian packages
# Description: Apt-p2p is a helper for downloading Debian packages
# files with APT. It will download any needed files from
# other Apt-p2p peers in a bittorrent-like manner, and so
# reduce the strain on the Debian mirrors.
