-# This program generates C/C++ code for efficiently manipulating

-# following format:
-#
-#   SYM | ARGS | TYPE | FUN?
-#
-# where SYM is the name of the constructor, ARGS is a
-# whitespace-separated list of argument types, TYPE is the type of the

-# `ATerm'), and the optional FUN is used to construct the names of the
-# build and match functions (it defaults to SYM; overriding it is
-# useful if there are overloaded constructors, e.g., with different
-# arities).  Note that SYM may be empty.
-#
-# A line of the form
-#
-#   VAR = EXPR
