hmm, it is terse and almost pure EBNF (see
http://www.cs.cmu.edu/~pattis/misc/ebnf.pdf).
I didn't encounter any gaps, but I did not check every line. I would be very
astonished
if it is incomplete. There are some tools to automagically convert EBNF to
syntax
diagrams, which are a bit easier to follow, but I don't have one at hand.

no problem.

yes there are. My version of CoCo (HP Mössenböcks CompilerCompiler) and M2O
(Niklaus Wirth's
Modula-2 to Oberon transpiler) are just such attempts.
