1. Introduction
Display Postscript (or DPS for short) is a rendering extension for
X11. DPS is slightly atypical in that it is based on code
mobility, the ability to send executable code from client to server.
Thus, a DPS client does not request that a line should be rendered;
instead, it uploads code to the server which, when executed, causes a
line to be drawn.
This document does not aim at teaching programming with DPS; it is
only a summary description of the DPS support code included with
XFree86. More information about DPS, including a DPS bibliography, is
available from the DPS extension site.

As all X11 extensions, DPS consists of client-side and server-side
components. The DPS client side consists of a number of libraries and
a number of tools for programming and configuration. The DPS server
side may consist either of an X server extension, or of a client-side
process known as the ``DPS agent.'' In this latter case, the term
``server-side'' is somewhat misleading.
At the time of writing, only the client side is included with XFree86;
the server side must be obtained separately. Please see
server side later in this document for
more information.
