######################### About this version #########################
ATDGEN_MAKE_VERSION = 1.0

# First public release.

######################### Setup and usage #########################
# Requires: GNU Make ("make" or "gmake" command), atdgen >= 1.2.0
# 
# Usage:
#
# For ATD files foo.atd and bar.atd, first place this in the Makefile:
#
#   ATDGEN_SOURCES = foo.atd bar.atd
#
# Options can be specified via the ATDGEN_FLAGS variable.
# For standard JSON output, use -j-std:
#
#   ATDGEN_FLAGS = -j-std
#
# Place this line after the definition of ATDGEN_SOURCES and ATDGEN_FLAGS:
#
#   include Atdgen.mk
# 
#
# Atdgen.mk creates rules for building the following files:
# - type definitions: foo_t.mli, foo_t.ml
# - biniou serialization/deserialization: foo_b.mli foo_b.ml
# - JSON serialization/deserialization: foo_j.mli, foo_j.ml
# [same with files bar*]
#
# Generated files are added to the variable ATDGEN_OUTFILES which
# is convenient for removing them. A "clean" target for an OCaml
# project might look like this:
# 
#   .PHONY: clean
#   clean:
#          rm -f *.o *.a *.cm* *~ *.annot $(ATDGEN_OUTFILES)
#
# The files in $(ATDGEN_OUTFILES) are automatically added to the TRASH
# variable, for convenience and compatibility with OCamlMakefile.
