Hongxu Jia - Aug. 2, 2013, 2:20 a.m.
list-packageconfig-flag.py will walk the METADIR and collect recipes which
have PACKAGECONFIG's flags.

The default display is to list recipes which have PACKAGECONFIG's flags in
METADIR. If option '-f' is used, it will list PACKAGECONFIG's flags and all
affected recipes in METADIR

EXAMPLE:
list-packageconfig-flag.py poky/meta poky/meta-yocto
RECIPE NAME          PACKAGECONFIG's flag
