  28 Usage:  ${progname//-/ } [--location <url>] [<package>] [<version>]
  29         Updates a package (which is autodetected if you are on it) to a
  30         given version, or simply download and regenerate checksums.
  31         Using --location you are able to specify which will be the new
  32         download location for this update.
  33
  34         ${progname//-/ } [--no-location] --md5 <url> (Alias: up)
  35         Updates a set of packages based on a remote .md5 file
  36         Using --no-location you tell the tool to not assume the download
  37         location of the md5 file for the updates but keep their individual
  38         download locations.
