This package contains Purr Data, which is a fork of Pure Data that
bundles a lot of useful extensions, and brings a modern HTML5-based
user interface.

Pure Data is an open source visual programming environment that runs on
anything from personal computers to embedded devices (ie Raspberry Pi)
and smartphones (via libpd, DroidParty (Android), and PdParty (iOS).
It is a major branch of the family of patcher programming languages
known as Max (Max/FTS, ISPW Max, Max/MSP, etc), originally developed
by Miller Puckette at IRCAM.

Pd enables musicians, visual artists, performers, researchers, and
developers to create software graphically without writing lines of
code. Pd can be used to process and generate sound, video, 2D/3D
graphics, and interface sensors, input devices, and MIDI. Pd can
easily work over local and remote networks to integrate wearable
technology, motor systems, lighting rigs, and other equipment. It
is suitable for learning basic multimedia processing and visual
programming methods as well as for realizing complex systems for
large-scale projects.
