This current version is a revision over the original I published two years ago. Most of the work done so far has been on the collection of operators. I have placed them on one page (so they may be browsed more easily), and I believe I have chased and filled in all the empty links of the original document. I have also worked to bring the document more in line with new HTML features and practices.Incidentally, if you read this document and find an error, please send me e-mail and let me know. I can't promise that I'll fix it right away, but I will at least add it to my list of things to do.
By the way, I wish to thank the many people who have written to point out errors in this document's predecessor. Many of the improvements are due to them. For those of you asking for a LaTeX version of this document, it is coming, I promise. :-)
I have created this document because I have noticed that many people on the Internet have been asking for some online document to get them started. I decided that this was a good opportunity.
You get what you paid for.
