==========================
FILE NAMING
==========================
-pageXXX
Php files with a name starting with 'page' are to be included directly in index.php, i.e. those are the pages
accessible through the link 'index.php?page=XXX'.




==========================
REQUEST VARIABLES
==========================

Each file that uses request or session vars should exlicitly define and document them first thing in the file. 
In the first place, this makes sure the system also works on servers with register_globals=Off, in the second place
it makes code maintenance easier because everyone can see what the input to a page is.

Use something like:

$ID="";
if (isset($_REQUEST["ID"])) {
    $ID=$_REQUEST["ID"];
}

See other files for example.

==========================
CHECK BASE
==========================
If you start an include file with the include 
require_once("checkBase.php");
the user will always be redirected to the front page of Aigaion
if (s)he accidentally points his or her browser to the location
of that include page. It is not necessary, but it is useful.
