Use shell, Perl, Python, your choice.
How would that work? I'm trying to make a kinda dynamic configuration, meaning that there is supposed to be a basic configuration accompanied by optional configurations. An optional configuration needs to make an entry for its sub-menu into the root menu if the optional configuration is available. If I was to write some program to create the root menu, I would always need to modify the program when new optional configurations are to be added so it could recognize them. That is something I would prefer to avoid. Hm, having that said, I can make it so that the optional configurations add themselves to the root menu. All they need is a line like AddToMenu Main "Games" PopUp Games Unfortunately, that raises the question how I can make it so that the entries in the root menu appear in a desired order and with the title at the top rather than somewhere in between the entries ... Is there a way to sort menu entries once no more entries are being added? I'm probably not the first one to try this. It can't be this difficult, can it?
