     unpackExtractPkgDESC will return a DCF matrix representing the
     DESCRIPTION file of the specified package.  It does this by
     unpacking the package using the appropriate method (currently
     options are limited to .tar.gz and .zip), and reading the file in
     manually.

     unpackSourcePkg will attempt to uncompress the .tar.gz package
     structure.

     unpackZipPkg will attempt to uncompres a .zip package using the
     system's "unzip" option.
