Usage: getpkg [options] package_name
getpkg is used to download and install .tgz Slackare packages from a Slackware
mirror site and install the package.
options:
-file STRING (find a package name by file name)
-list (list available packages)
-mirror URL (override default mirror URL)
-search STRING (search packages for STRING)
-setmirror URL (set default mirror URL)
-root /mnt (install someplace else, like /mnt)
-wget /path/to/wget
-selfupdate (update package listings from mirror)
-upgrade (using upgradepkg instead of installpkg)
Example URL:
http://mirror.server.org/path/to/slackware-XX.X/
