=item installables
Returns a list of the binary and udeb packages listed in the
F<debian/control>.
=cut

}
=item installable_package_type (NAME)
Returns package type based on value of the Package-Type (or if absent,
X-Package-Type) field. If the field is omitted, the default value
"deb" is used.
If NAME is not an installable listed in the source packages
F<debian/control> file, this method return C<undef>.

}
=item installable_fields (PACKAGE)
Returns the Deb822::Section object for the installable. Returns an
empty object if the installable does not exist.
