weka-virtualenv supports installing Weka now

Just added a new command called install to my weka-virtualenv tool. With this command, you can comfortably download and install Weka versions from Sourceforge.net. It uses the platform-independent zip files of Weka, listed in a manually maintained list in the project’s github.com repo.

Have a look at the documentation for an example:

The new release is 0.0.17.
