This page has changed its file-name and U.R.L.

      The page you are trying to reach has changed its name to something more descriptive, and all links on my web site have been changed accordingly. If you have got here now, it is probably because you bookmarked it earlier, before I changed its name - or else you may have reached the page which links to it from a search engine, using a cached - and out-of-date - copy kept by the search engine. (I know that at least Google and All the Web have older copies of some of my web pages.)
      Please go to the new location for this page - and, while you are there, please update your bookmark to its current U.R.L. This cautionary page is not guaranteed to remain here permanently, and will be one of the first things to go if I start to run out of room for new web site pages.
      In fact, I recommend that you bookmark only the front page of this web site, because it is always possible other pages could change name and/or contents as I reorganize the web site in response to changing or growing contents, and I will not always necessarily use a caution page such as this to cover all future changes.
      Thank you, and sorry for any inconvenience over this.
