zubr (LALR(1) parser generator)

ZUBR is a LALR(1) parser generator for building syntax analyzers
from user-written grammar specifications.
Its specification language is historically compatible with AT&T Yacc
and Berkeley Yacc, with additional ZUBR extensions.

ZUBR supports semantic actions, precedence, error recovery, and
parser diagnostics such as the generated z.output file.

Input and output text is UTF-8; internal text processing uses UCS-2.
The current implementation uses LibMPU and LibMPUIO.

Requires:
  libmpu   >= 1.0.28
  libmpuio >= 1.0.8
