Initial revision
Move WEB_DIR and URL_DIR to the front and make them variables instead
of constants so we change generate pages on hissa and externally.
Make the NIST web site the default URL directory.  Change ename to
alphname to avoid confusion with the rest of the code, where ename
means something else.
Print AKA and WEB information on the entry pages.
Abstract out the functionality to add a term to the in-memory
dictionary so we can create terms from file entries or from AKA
names.  Make other changes needed to generate AKA entries.  Count the
number of terms in the index separately from the number of terms files
read.
Move .concl and .intro files to a new subdirectoryL Pages.
Use "A" (instead of "Z") for suffix for duplicate alphaName so it is
sorted close to the word without the suffix.  Actual, that is, display
name, duplicates are reported when the index is written.
Move routines here from mkterms which are now shared with the new
mkauthors.  Add new defines for the Other directory and the
contributors (authors) page.
Handle HTML special characters, like &ouml;, in names.
Remove all special characters from file names generated for AKA or WEB
entries, such as period (r.e. language) and apostrophe (Ackerman's function).
Check for funny characters at the end of AKA or WEB entries.
Create database entries for WEB variants.
Report the total number of all entries, including web variants,
separately from the number of entries in the main index.
Don't use WBE or AKA entries for cross references.  The "standard
name" should be used in any entry to link directly to the definition.
Try to make HTML file names unique by making sure there is no term
file with the same name.
Change "8" to a name to be alphabetized.
Correct a commented-out debugging statement.  Add another statement
that might be helpful.
Add an explicit error message (rather than just giving debugging
information and exiting).
Don't rewrite internal links (either ../ or nist.gov).
Bug fix: make sure nothing is left over from preceding AKA or WEB
definitions.
Add a special hard-wired conversion from Latex-style doubled quotes
( and '') into doublequotes (").
Add new fields to more precisely describe information.
Explicitly remove \n, instead of using "chop", in case file (and line)
doesn't end with a new line.
Correct two minor typos.
