Usage: `basename ${0}` --file <path>|--folder <path> \
    [--override-svn-rev <rev>] [--extra-version-string <string>] [--without-hardening]

Exports the VirtualBox host kernel modules to the tar.gz archive or folder in \
<path>, optionally adjusting the Make files to build them without hardening.

Examples:
  `basename ${0}` --file /tmp/vboxhost.tar.gz
  `basename ${0}` --folder /tmp/tmpdir --without-hardening"
