\part{Getting Started}

This part is intended to help you get started with the \pgfname\
package. First, the installation process is explained; however, the
system will typically be already installed on your system, so this can
often be skipped. Next, a short tutorial is given that explains the
most often used commands and concepts of \tikzname, without going into
any of the glorious details. At the end of this section you will find
some, hopefully useful, hints on how to create ``good'' graphics in
general. The information in this section is not specific to
\pgfname.

\part{Libraries and Utilities}
\label{part-libraries}

In this part the library and utility packages are documented. The
library packages provide additional predefined graphic objects like
new arrow heads, or new plot marks. These are not loaded by default
since many users will not need them.

The utility packages are not directly involved in creating graphics,
but you may find them useful nonetheless. All of them either directly
depend on \pgfname\ or they are designed to work well together with
\pgfname\ even though they can be used in a stand-alone way.

\part{The System Layer}
\label{part-system}

This part describes the low-level interface of \pgfname, called the
\emph{system layer}. This interface provides a complete abstraction of
the internals of the underlying drivers. 

Unless you intend to port \pgfname\ to another driver or unless you intend
to write your own optimized frontend, you need not read this part.

In the following it is assumed that you are familiar with the basic
workings of the |graphics| package and that you know what
\TeX-drivers are and how they work.
