Information for browsing this article

This article comprises two parts; a technical introduction and a descriptive part. Both contain "working demonstrations" which will require either particular configuration of the Web client you are using to view this article, or additional software present on your computer system. Whilst the ultimate objective is to try to eliminate such additional requirements so that the article is "ready to read" immediately, the current state of development of the World Wide Web does not allow this yet. Summarised below is what you would have to do to unlock the full functionality of this article.

The article is best viewed with a "tables aware" browser. Most modern clients support this, although some (i.e X-Mosaic) have problems with images in tables.
You will need either a chemical helper such as RasMol or the equivalent Netscape "plug-in" such as Chemscape Chime to view "pdb" files embedded in various locations. The helper MIME type will need to be correctly set
A number of Netscape 2.x specifics are included. These should "degrade" on non-Netscape browsers such that alternative information is presented (or the information omitted!). This includes client-side image maps, support for <embed> and <applet> tags, support for Javascript etc.
Reference is also made to other external chemistry programs such as ChemDraw, ISIS/Draw and Base, Beilstein Commander, which the reader would have to acquire to try out the appropriate demonstrations.
To connect to remote on-line terminal based services, the user will have to have a Telnet client resident on their local computer.
One demonstration includes an in-line Java applet, which would have to be viewed using a "Java aware" client. Another requires the user to have access to a VRML viewer or plug-in.
