Options:

        * Email address to which this report will be assigned

    -p | --product <product>

        * Bugzilla product to fail this report against

    -d | --debug

        * Enable debugging output (also assigns QA contact as you)

    -r | --reference

        * Any additional references to assign to this report,

          e.g. FATE#123456

    -h | --help

    	* Print this message

Notes:

  * If no email address specified, the username component of git-config

    user.email will be used with @suse.com appended.

  * If no product is specified, the \$BUGZILLA_PRODUCT variable in

    rpm/config.sh will be used, if present.

  * If the patch already contains references, they will be preserved with

    the bugzilla ID created and any additional references specified with

    --reference appended.  Otherwise, a new References tag will be created.

  * The patch will be updated with new references prior to upload.

  * Use of this script requires a ~/.bugzillarc with the following contents:

    [apibugzilla.suse.com]

    user = <bugzilla username>

    password = <bugzilla password>

    authtype = basic
