+Usage: explodepkg 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.
