Author: Till Tantau <tantau@cs.tu-berlin.de>
Abstract: This is a high quality manual for PGF and TikZ, including
several tutorials and a detailed reference. The manual is divided into
main three sections, the Frontend Layer, the Basic Layer and the System
layer. The Frontend includes TikZ and corresponds to user level commands.
The Basic and System Layers correspond to increasingly low level
functionality.
