seeded-in-ubuntu(1)					      General Commands Manual					       seeded-in-ubuntu(1)

NAME

       seeded-in-ubuntu - Determine whether a package is safe to upload during a freeze

SYNOPSIS

       seeded-in-ubuntu [options] package...

DESCRIPTION

       Lists all the current daily images containing the specified packages.  Or whether the package is part of the supported seed.

       If it isn't on an image, it should be safe to upload.  During the final freeze, one should avoid packages in the supported seed too.

       An index of the current manifests is downloaded from UbuntuWire.

OPTIONS

       -b, --binary
	      The  packages  specified	are  binary packages.  This is faster than source packages, as otherwise we must query LP to determine the
	      binary packages that every specified source package builds.

       -u URL, --data-url=URL
	      URL for index of seeded packages.  Default: UbuntuWire's service at http://qa.ubuntuwire.org/ubuntu-seeded-packages/seeded.json.gz.

       -h, --help
	      Display a help message and exit

EXAMPLES

       All the images that contain unity:

	      seeded-in-ubuntu -b unity
