-ANNOUNCE: Harpy 0.4 - Runtime code generation for x86 machine code
-
-We are pleased to announce the release of Harpy 0.4, a library for
-runtime code generation for x86 machine code.
-
-Harpy is available from Hackage:
-
-  http://hackage.haskell.org/cgi-bin/hackage-scripts/package/harpy-0.4
-
-Also see Harpy's homepage, which features two tutorials and access to
-the darcs repo (and to the Haddock documentation, until it is available
-from Hackage, too):
-
-  http://uebb.cs.tu-berlin.de/harpy/
-
-Harpy is supposed to be built with GHC 6.8 and GHC 6.6 (with Cabal 1.2
-or greater).  Please report any build problems you encounter.
-
-This release features the following additions and fixes:
-
-- New convenience top-level module "Harpy", which re-exports
-  Harpy.CodeGenMonad, Harpy.Call and Harpy.X86Assembler
-
-- It is now possible to override Harpy's automatic code buffer
-  management.  The new field 'customCodeBuffer' in the type
-  'CodeGenConfig' can be set to 'Just (buf, size)', where 'buf' is a
-  pointer to a memory region of 'size' bytes.  Harpy will then use the
-  supplied code buffer and will not perform any automatic code buffer
-  allocation on overflow.  Overflow checking is still performed and
-  will result in an exception in the CodeGen monad.
-
-- When using the high-level assembler in X86Assembler, the code buffer
-  is automatically protected from overflow.
-
-- Floating point operations added to X86Assembler (only for double
-  operands yet).
-
-- Preliminary support for SSE instructions.  Currently, only the
-  packed and scalar floating-point arithmetic operations are supported
-  (both in the low-level module Harpy.X86CodeGen and as methods in
-  Harpy.X86Assembler)
-
-- Code buffer default size has been increased from 128 to 4096 bytes.
-
-- The CodeGenMonad fails when a label is defined twice.
-
-- It is now possible to associate names with labels, using the new
-  operation newNamedLabel.  The given names will show up in the
-  disassembly, which makes debugging of generated code much easier.
-
-- The doc directory contains a second, slightly larger tutorial now.
-
-- The examples/evaluator directory contains a small example
-  interpreter for arithmetic expressions, which translates expressions
-  entered at the keayboard to machine code on the fly.  This is the
-  demo program we presented at the Haskell Workshop 2007.
-
-Happy Haskell Hacking with Harpy,
-
-  Martin and Dirk
