### Building ###

Prerequisites:
You need a recent version of the RapidMiner 5.x source code. It should be 
located at "../RapidMiner_Vega" relative to this directory. If this does not 
apply, change the "rm.dir" property in the build.xml file.

Go for it:
Just type

 ant

for building the plugin. If you want it packaged, type

 ant createJar

and if you are running RapidMiner from your RapidMiner_Vega source directory
you can also type

 ant installJar

which packages the plugin and places it in "RapidMiner_Vega/lib/plugins".

[Then start RapidMiner.]

That's it.

Enjoy,
Ben
