The basic format of a ChunkDesc is:

chunk "token" "longer name" "help info"
    Name String 1 "Name" ""
    [other Property Descriptions]
    ...
    end

The first line contains the token chunk, followed by three strings. The token is used in programs to refer to the ChunkDesc. The name is a longer name that is used in graphical interfaces instead of the token. (The name can contain spaces, the token must not). The help info is a string shown in the graphic interface. All three strings must be defined, though the help string can be empty ("").

The first line is followed by one or more Property Descriptions, followed by the token end. Note that the first property description must always be for the "Name" property - this is used to give a unique name to every ConfigChunk using this ChunkDesc. If there is no "Name" PropertyDesc, one will be added by the loader.
