There's no parser generator; its primary purpose is to document how a format looks and works (similar to what ABNF and EBNF do). I am trying to make it consistent enough that tools could be made for it, however. The & is something I added later, and I thought I'd updated all of the examples but I must have missed some. Using whitespace as an operator was just causing too much trouble and making the more complex grammars harder for a human to follow, which is why I opted to make every operation require an actual symbol, and leave whitespace without semantic value.
