I couldn't quickly find a formal definition, but from this example and the
examples in my security book it looks like a config file is defined as
something like:

ConfigFile := AppConfig+
AppConfig := AppName '{' LoginModule+ '}'
LoginModule := ModuleName ModuleControlFlag ModuleOptions* ';'
ModuleControlFlag := 'REQUIRED' | 'REQUISITE' | 'SUFFICIENT' | 'OPTIONAL'
ModuleOptions := OptionName '=' OptionValue

Where the *Names and *Values are either strings or fully qualified class names.

Is there much more needed to be parsed then something like the above? Maybe in
practise the format isn't as strict or precisely defined as above, in that case
it becomes a bit more tricky, but just having a simple "strict" parser for the
above format seems helpful.
