Just posted a basic intro tutorial on using the OptionsFile class for those that are interested.
From the Tutorial:
OptionsFiles are used almost everywhere in GameCore. Everything from the most basic config file, through all of the various types of Properties files are loaded using the same OptionsFile interface that we can use as developers making games with GameCore. So when we go through and create our own custom configuration files, it?s actually calling the same functions that GameCore uses when parsing things like OPR files and even World files themselves.
I use OptionsFile's all over the place in my own project's, if you are doing any kind of serious development in GameCore, I highly recommend becoming familiar with them.
