I've written a program that gives you choices.

1.0: Title
1.1: choice 1
1.2: choice 2
1.3: choice 3

Each choice can have followups and can be added through an admin app that creates the file.

1.0: Title
1.1: choice 1
1.1-2.0: Title2
1.1-2.1: Followup of choice 1
1.1-2.2: Followup of choice 1
1.1-2.3: Followup of choice 1
1.2: choice 2
1.3: choice 3

That means everything's variable... You can create as many choices as you want...

So Yes, I want to be able to edit the file, it represents a choice making mechanism, and no it can't be changed because the rest is allready written. It's only that last item I explained here that's a problem.
