Chapter 1

Introduction

This chapter gives an overview, describes the changes since Version 1, and discusses the kinds of images which are allowed.

The maintainer of this document will attempt to maintain an on-line version of this Guide as well as a Postscript version which can be ftp'd. Unfortunately, one version will not always look like the other. Look for specific differences in the Figures and in the way displayed "buttons" are represented.

• The figures in the Postscript version will be grayscale whereas the on-line version contains GIF-colored figures. The figures themselves should be numbered consistently between versions. The figure-numbering scheme is sequential within a chapter; thus, Figure 4.5 would appear in Chapter 4 but not necessarily in Chapter 4, Section 5.

• Operating the program consists almost entirely of using a mouse to move a cursor to a displayed "button" and clicking the button. In the Postscript version, a button is labeled and enclosed in a box. In the HTML version, a button is designated as [Press].
