Quarkpy is the module, composed of the files in the quarkpy subfolder, which provides both the basic facilities that Python provides for the Delphi code, and also the basic facilities that plugins depend on and add to.

It can be thought of as a big and as yet poorly documented API; learning your way around it is one of the biggest obstacle to getting good at QuArK Python coding.

Hopefully the rather paltry info here will be augmented before too long.
