Usage: explodepkg.sbopkglint package_name [package_name2, ...]
Explodes a Slackware compatible software package
(or any tar+{gzip,bzip2,lz,xz archive) in the current directory.
Equivalent to (for each package listed):
( umask 000 ; cat package_name | COMPRESSOR -dc | tar xpvf package_name )
Note: This should only be used for debugging or examining packages, not for
installing them. It doesn't execute installation scripts or update the package
indexes in /var/lib/pkgtools/packages and /var/lib/pkgtools/scripts.
Note: explodepkg.sbopkglint should only be called by sbopkglint. If
you need to extract a package with explodepkg, you should be using the
real one from Slackware's pkgtools (/sbin/explodepkg).
