Name either curves or curvesls in the \usepackage command at the top of your main .tex file e.g.,
__
\documentclass[11pt]{article}
_\usepackage{curves}
_
curves.sty
or curvesls.sty should be in the default or a texinput directory. For the older LATEX 2.09 name them in the \documentstyle command.
Do not combine
curves or curvesls with bezier in this command. They contain a fast powerful replacement for \bezier. Drawings using \bezier should not change their appearance.
PICTEX
is a large set of TEXnical drawing macros for plain TEX which LATEX pictures can also use. PICTEX requires a big TEX. I have not checked compatibility with curves or curvesls because I do not use PICTEX. _
curvesls.sty uses line drawing \specials to reduce required memory and increase speed. As originally supplied it uses the \specials of emTEX by Eberhard Mattes for IBM PC compatibles. emTEX is available from CTAN and the TEX Users' Group. The emTEX \specials are also available for Tomas Rokicki's dvips. If you use dvips, ask if they have been compiled in. To use other line drawing \specials substitute them at curvesls.sty's start. Your system guru may do this for you. You can test curvesls.sty after substituting \specials, by replacing curves with curvesls in this file's \documentstyle command. This file looks the same LATEXed with either curves or curvesls.
A drawing frequently uses auxiliary commands to size, place, label and caption it. The following commands draw the box in Figure 1 on page 19:
__
\begin{figure}
_\begin{center}
_\setlength{\unitlength}{1mm}
_\begin{picture}(100,50) \large\sf
_\linethickness{1mm}
_\put(20,5){\framebox(60,40){BOX}}
_\end{picture}
_\end{center}
_\caption{This is a box.}
_\label{box}
_\end{figure}
_
Lamport explains these commands. This example is for those unfamiliar with the LATEX picture environment. The following examples avoid the figure environment but it is often essential.
