[vuplus_bitbake] / TODO

On popular request by popular people a list of tasks to-do:

        -Kill insecure usage of os.system either by properly escaping
         the strings or a faster replacement not involving /bin/sh
        -Unpack only the real file and do not use wild-cards (is that the case)
        -Introduce a -p option to automatically hotshot/profile the
         run
        -Cache dependencies separately and invalidate them when any file
         changed.
        -Fix data_dict.py
        -...


DONE:
·       -On generating the inter package deps do not parse each file multiply
·        times.
        -We build the lists while parsing the data now
·       (WAS: Do not generate the world dependency tree, only when someone
·             requests it.
