No, they have absolutely nothing to do with BSD .pkg files.. they're  
descendants of NeXT .pkg bundles.

This will extract a .pkg to the current directory
pax -rzf Foo.pkg/Contents/Archive.pax.gz

There is a CLI version of Install.app, which may or may not work  
depending on how hosed his system is: man 8 installer
