There is an incomplete manual in doc/nyacc/.

There is a demo program calc.scm in examples/nyacc/lang/calc.  Easy starter:
  $ cd examples/nyacc/lang/calc
  $ ./calc
  2 + 2 => 4

The module code is in module/nyacc.  Modules are imported as follows:
  (use-modules (nyacc lalr))
  (use-modules (nyacc lex))

If you have a personal guile directory then you can copy modules/nyacc
to that directory.  To install in the global guile distribution:
  user$ sudo -s 
  root# cd module
  root# make -f Makefile.nyacc install
  root# exit
  user$

The syntax and nomenclature should be considered not stable.
