1. Protocol

The protocol provided by the mpk package can be thought of as a cross between skel and dsp. mpk-project and mpk-component inherit directly from sk-project and sk-component. Many of the generic methods provided operate on media-file objects and use dsp internals.

2. Configuration

mpk supports configuration in the standard s-expression format. Where possible we also support the default file formats used by the tools we rely on (picard, transmission, mpd).
