-# This program generates C/C++ code for efficiently manipulating
-# ATerms.  It generates functions to build and match ATerms according
-# to a set of constructor definitions defined in a file read from
-# standard input.  A constructor is defined by a line with the
-# 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
-# resulting ATerm (which should be `ATerm' or a type synonym for
-# `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
-#
-# causes a ATerm variable to be generated that is initialised to the
-# value EXPR.
-#
-# Finally, a line of the form
-#
-#   init NAME
-#
-# causes the initialisation function to be called `NAME'.  This
-# function must be called before any of the build/match functions or
