It would be very helpful to take the user configurable
variables out of defined.inc.php, and to put them in
their own file. This would make upgrading easier. I
have build scripts that download and package your code
into an RPM, and when I went from version 1.0.4 to
1.0.5, I encountered problems. If these were in a
seperate file, it would be easier to package.
Just a suggestion.
