subjects of many files overlap so I've included some files, with `->' in
their names, just to help users find the files they are interested in.
        There is a category list is in the file `Archive.Index'.  All the
files that have `->' in their name are for indexing only.  The file
`Abstracts' contains a brief description of every file in the archive.  I
use it to determine where to put postings.

        I plan to change the filename from Archive.Index to Categories once
Lorre Smith's index of the archive (see Subject 8, below) is integrated
into the archive.  The WWW interface already includes a Categories.html
file.
