//Usage: installpkg [options] <package_filename>
//
//Installpkg is used to install a .t{gz,bz,lz,xz} package like this:
// installpkg slackware-package-1.0.0-i486-1.tgz (or .tbz, .tlz, .txz)
//
//options: --warn (warn if files will be overwritten, but do not install)
// --root /mnt (install someplace else, like /mnt)
// --infobox (use dialog to draw an info box)
// --terse (display a one-line short description for install)
// --terselength <length> (line length in terse mode - default is
// the number of columns available)
// --menu (confirm package installation with a menu, unless
// the priority is [required] or ADD)
// --ask (used with menu mode: always ask if a package should be
// installed regardless of what the package's priority is)
// --priority ADD|REC|OPT|SKP (provide a priority for the entire
// package list to use instead of the priority in the
// tagfile)
// --tagfile /somedir/tagfile (specify a different file to use
// for package priorities. The default is "tagfile" in
// the package's directory)
// --threads <number> For xz/plzip compressed packages, set the max
// number of threads to be used for decompression. Only has
// an effect if a multithreaded compressor was used, and then
// only on large packages. For plzip, the default is equal to
// the number of CPU threads available on the machine. For xz,
// the default is equal to 2.
// --md5sum (record the package's md5sum in the metadata file)
// --no-overwrite When extracting the package, do not overwrite
// existing files. Usually, this option should not be used.
// It exists so that upgradepkg can use it for the second
// installation pass. The first pass has already overwritten
// the previous package's files, and this will catch the few
// corner cases without generating unnecessary writes.
