Usage:

    where <pattern> is a match against a repo (URL, path, whatever)
    -v reverses the pattern matching.

Warning:

    This script, though very useful, is rather rudimentary!!!!

    Before using it as a source for removing packages, make sure to _check_ the
    output for possible false positives, and feel free to improve this script.

Examples:
    List out all packages from any uninett.no repo:
    $ apt-origin uninett.no

    List out all packages uninett.no or puppetlabs.com
    $ apt-origin uninett.no puppetlabs.com

    List out all packages neither from debian.org nor uninett.no
    $ apt-origin -v uninett.no debian.org

    List out all packages from any repo named jessie/mp
    $ apt-origin jessie/mp

    List out all packages from backports
    $ apt-origin backports

    List out all packages from that do not have default \"priority\" of 500
    $ apt-origin -v 500
