+ * This imagemap module started as a port of the original imagemap.c
+ * written by Rob McCool (11/13/93 robm@ncsa.uiuc.edu).
+ * This version includes the mapping algorithms found in version 1.3
+ * of imagemap.c.
+ *
+ * Contributors to this code include:
+ *
+ * Kevin Hughes, kevinh@pulua.hcc.hawaii.edu
+ *
+ * Eric Haines, erich@eye.com
+ * "macmartinized" polygon code copyright 1992 by Eric Haines, erich@eye.com
+ *
+ * Randy Terbush, randy@zyzzyva.com
+ * port to Apache module format, "base_uri" and support for relative URLs
+ *
+ * James H. Cloos, Jr., cloos@jhcloos.com
+ * Added point datatype, using code in NCSA's version 1.8 imagemap.c
+ * program, as distributed with version 1.4.1 of their server.
+ * The point code is originally added by Craig Milo Rogers, Rogers@ISI.Edu
+ *
+ * Nathan Kurz, nate@tripod.com
+ * Rewrite/reorganization.  New handling of default, base and relative URLs.
+ * New Configuration directives:
+ *    ImapMenu {none, formatted, semiformatted, unformatted}
+ *    ImapDefault {error, nocontent, referer, menu, URL}
+ *    ImapBase {map, referer, URL}
+ * Support for creating non-graphical menu added.  (backwards compatible):
+ *    Old:  directive URL [x,y ...]
+ *    New:  directive URL "Menu text" [x,y ...]
+ *     or:  directive URL x,y ... "Menu text"
+ * Map format and menu concept courtesy Joshua Bell, jsbell@acs.ucalgary.ca.
+ *
+ * Mark Cox, mark@ukweb.com, Allow relative URLs even when no base specified

+ *  URL Rewriting Module
+ *
+ *  This module uses a rule-based rewriting engine (based on a
+ *  regular-expression parser) to rewrite requested URLs on the fly.
+ *
+ *  It supports an unlimited number of additional rule conditions (which can
+ *  operate on a lot of variables, even on HTTP headers) for granular
+ *  matching and even external database lookups (either via plain text
+ *  tables, DBM hash files or even external processes) for advanced URL
+ *  substitution.
+ *
+ *  It operates on the full URLs (including the PATH_INFO part) both in
+ *  per-server context (httpd.conf) and per-dir context (.htaccess) and even
+ *  can generate QUERY_STRING parts on result.   The rewriting result finally
+ *  can lead to internal subprocessing, external request redirection or even
+ *  to internal proxy throughput.
+ *
+ *  This module was originally written in April 1996 and
+ *  gifted exclusively to the The Apache Software Foundation in July 1997 by
+ *
+ *      Ralf S. Engelschall
+ *      rse engelschall.com

+/* mod_speling.c - by Alexei Kosut <akosut@organic.com> June, 1996
+ *
+ * This module is transparent, and simple. It attempts to correct
+ * misspellings of URLs that users might have entered, namely by checking
+ * capitalizations. If it finds a match, it sends a redirect.
+ *
+ * Sep-1999 Hugo Haas <hugo@w3.org>
+ * o Added a CheckCaseOnly option to check only miscapitalized words.
+ *
+ * 08-Aug-1997 <Martin.Kraemer@Mch.SNI.De>
+ * o Upgraded module interface to apache_1.3a2-dev API (more NULL's in
+ *   speling_module).
+ * o Integrated tcsh's "spelling correction" routine which allows one
+ *   misspelling (character insertion/omission/typo/transposition).
+ *   Rewrote it to ignore case as well. This ought to catch the majority
+ *   of misspelled requests.
+ * o Commented out the second pass where files' suffixes are stripped.
+ *   Given the better hit rate of the first pass, this rather ugly
+ *   (request index.html, receive index.db ?!?!) solution can be
+ *   omitted.
+ * o wrote a "kind of" html page for mod_speling
+ *
+ * Activate it with "CheckSpelling On"

+ * mod_userdir... implement the UserDir command.  Broken away from the
+ * Alias stuff for a couple of good and not-so-good reasons:
+ *
+ * 1) It shows a real minimal working example of how to do something like
+ *    this.
+ * 2) I know people who are actually interested in changing this *particular*
+ *    aspect of server functionality without changing the rest of it.  That's
+ *    what this whole modular arrangement is supposed to be good at...
+ *
+ * Modified by Alexei Kosut to support the following constructs
+ * (server running at www.foo.com, request for /~bar/one/two.html)
+ *
+ * UserDir public_html      -> ~bar/public_html/one/two.html
+ * UserDir /usr/web         -> /usr/web/bar/one/two.html
+ * UserDir /home/ * /www     -> /home/bar/www/one/two.html
+ *  NOTE: theses ^ ^ space only added allow it to work in a comment, ignore
+ * UserDir http://x/users   -> (302) http://x/users/bar/one/two.html
+ * UserDir http://x/ * /y     -> (302) http://x/bar/y/one/two.html
+ *  NOTE: here also ^ ^
+ *
+ * In addition, you can use multiple entries, to specify alternate
+ * user directories (a la Directory Index). For example:
+ *
+ * UserDir public_html /usr/web http://www.xyz.com/users
+ *
+ * Modified by Ken Coar to provide for the following:
+ *
+ * UserDir disable[d] username ...
+ * UserDir enable[d] username ...
+ *
+ * If "disabled" has no other arguments, *all* ~<username> references are
+ * disabled, except those explicitly turned on with the "enabled" keyword.
