$PROG - build wrapper script for Emdebian Grip

Syntax: $PROG [COMMAND] [DPKG-OPTIONS]

Commands:
   --debuild:               use debuild instead of dpkg-buildpackage
-a|--arch ARCH:             cross-build using dpkg-buildpackage -a
-n|--dry-run:               print the commands but do not build
-V|--vendor VENDOR:         DEB_VENDOR support.

-?|-h|--help|-version:      print this help message and exit

Simple wrapper for dpkg-buildpackage that runs the built package
through emgrip. This results in both types of packages existing in
the parent directory.

The DEB_VENDOR environment variable is supported as well as the
-V|--vendor command line option.

DPKG-OPTIONS

Any unrecognised options are passed directly to dpkg-buildpackage,
there is no need for '--' .
