% The MLDS back-end.
%
% This package includes
% - the MLDS data structure, which is an abstract
%   representation of a generic imperative language;
% - the MLDS code generator, which converts HLDS to MLDS;
% - the high-level C back-end, the Java back-end, the .NET back-end,
%   and a wrapper for the assembler back-end,
%   each of which convert MLDS to their respective target language.
%
% The main part of the assembler back-end, which converts MLDS
% to GCC's internal abstract syntax trees and then invokes the
% GCC back-end to convert this to assembler, is in a package of
% its own, so that this package doesn't depend on the GCC back-end.
