approx - 5.10-1 main

Approx is an HTTP-based proxy server for Debian-style package archives.
It fetches files from remote repositories on demand,
and caches them for local use.
.
Approx saves time and network bandwidth if you need to install or
upgrade .deb packages for a number of machines on a local network.
Each package is downloaded from a remote site only once,
regardless of how many local clients install it.
The approx cache typically requires a few gigabytes of disk space.
.
Approx also simplifies the administration of client machines:
repository locations need only be changed in approx's configuration file,
not in every client's /etc/apt/sources.list file.
.
Approx can be used as a replacement for apt-proxy,
with no need to modify clients' /etc/apt/sources.list files,
or as an alternative to apt-cacher.
