The one thing that all Chunks have in common is that they all have names. Names are used to distinguish between multiple Chunks of the same type. It's important that Chunks have unique names. If Juggler reads two ConfigChunks that have the same name, it will assume that the second one is a redefinition or reconfiguration of the first one, and it will forget the first one and just use the second definition. The rest of the Chunk consists of a list of Properties.
Properties are individual pieces information.
Continuing our example with a Flock of Birds tracking system, the Properties would include things like the name of the serial port to connect to, the baud rate to use, the positional offset, and so on. Different properties take different kinds of values - Port takes a string, while Baud Rate takes an integer. The Translation property is interesting because it takes three separate floating point numbers. If you've read this far, you know what Juggler's config files are, and you know what they're made of - lists of ConfigChunks. You also know that there are a lot of different kinds of ConfigChunks.
