s a general illustrating

DP is a highly interactive circuit drawing program that runs on a PERQ computer, create the description of an clcctronic circuit in a graphical form that corrcsponds normally represented in logic diagrams.

DP is a purely graphic editor: it does not try to "understand" what the user is dra interpretation is performed by post-processors that are able to extract electrical drawings. This makes the program itself reasonably simple, giving the designer g~ introduces a clear separation between the tool used to create a drawing and the "m itself, with the result of a much wider range of possible applications.
tZlthough primarily intended as a tool for drawing electronic cjrcuits, DP may be used program, able to draw arbitrarily complex pictures.

Chapter 1 explains how to build the program on a new machine and how to start it.
