# The Menhir-generated parser

# In order to avoid a build-time dependency on Menhir,
# we store the result of the parser generator (which
# are OCaml source files) and Menhir's runtime libraries
# (that the parser files rely on) in boot/.

# The rules below do not depend on Menhir being available,
# they just build the parser from boot/.

# See Makefile.menhir for the rules to rebuild the parser and update
# boot/, which require Menhir. The targets in Makefile.menhir
# (also included here for convenience) must be used after any
# modification of parser.mly.
include Makefile.menhir

# To avoid module-name conflicts with compiler-lib users that link
# with their code with their own MenhirLib module (possibly with
# a different Menhir version), we rename MenhirLib into
# CamlinternalMenhirlib -- and replace the module occurrences in the
# generated parser.ml.
