netselect-apt - create sources.list for the fastest Debian mirrors
netselect-apt [ OPTIONS ] [ stable | testing | unstable | experimental | woody | sarge | etch | sid ]
netselect-apt automatically creates a sources.list file for using with apt
for the specified distribution by downloading the list of Debian mirrors using wget and
choosing the fastest servers (both US and non-US) using netselect . The output file is
written to OUTFILE .
If there is a file called mirrors_full in the current directory which lists the Debian
mirrors, netselect-apt uses that rather than downloading another copy.
stable | testing | unstable | experimental | woody | sarge | etch | sid
Specify which distribution of Debian to use. By default stable is used.
