***NOTE NOTE NOTE **********************************************************

THIS IS A BIG CHANGE!

I've renamed the "reading" module to "resource".

This meant changing quite a few references throughout Moodle.

The automatic upgrade process should work OK (it worked OK on my
development server) and there shouldn't be any problems.

BUT PLEASE PROCEED WITH CAUTION AND KEEP BACKUPS OF EVERYTHING
UNTIL I HAVE A FEW MORE TESTS!   If you upgrade please let me know.

One thing that will break are any hard-coded links within forum messages.

What I will be doing to fix this on my apache server is to add this to
httpd.conf:

Redirect /mod/reading/ http://moodle.com/mod/resource/

Sorry about any inconvenience, but it's better this is done sooner than later.
