# Builds the M2comp compiler (step 1: Coco/R syntax front end).
# Requires GNU Modula-2 (gm2 -fiso) and the Coco/R CR binary.
#
# Usage: ./build.sh   (from the m2comp directory)
#
# All sources live in src/ (grammar, frames, hand modules, generated
# scanner/parser/driver). The binary links to ./M2comp (project root).
#
# Pipeline: src/M2comp.atg -> src/M2compS/M2compP/M2comp (.mod)
#           -> gm2 -fiso -> ./M2comp
