@nishadhka Thanks for the addition, both of these packages would make great additions to berryconda!

Neither of these recipe include a build.sh script or a build/script entry in the meta.yaml file. Therefore nothing is included in the conda package when I build these. Perhaps these scripts were not checked into git?

Also, the pybluez package is a wrapper around the bluetooth bluez library. For compatibility it would be good to provide a conda package for this library in addition to the wrapped.

Finally, there are some conventions, such as jinja templates and using pypi.io for the package source, that I have been using in these recipes which make it easier to maintain and update . Although not needed modifying these recipes to follow these would be great. The appdirs recipe is a good example to work from.

Let me know if you need any help updating these, I'd be happy to offer my assistance.
