 Hammer is a parsing library. Like many modern parsing libraries, it provides a parser combinator interface for writing grammars as inline domain-specific languages, but Hammer also provides a variety of parsing backends. It's also bit-oriented rather than character-oriented, making it ideal for parsing binary data such as images, network packets, audio, and executables.

 Features
 ========
 * Bit-oriented -- grammars can include single-bit flags or multi-bit constructs that span character boundaries, with no hassle

 To build bindings, pass a "bindings" argument to scons, e.g. `scons bindings=python`. `scons bindings=python test` will build Python bindings and run tests for both C and Python. `--variant=debug` is valid here too. You can build more than one set of bindings at a time; just separate them with commas, e.g. `scons bindings=python,perl`.

 The .NET bindings are for Mono 3.0.6 and greater. If you're on a Debian-based distro that only provides Mono 2 (e.g., Ubuntu 12.04), there are backports for [3.0.x](http://www.meebey.net/posts/mono_3.0_preview_debian_ubuntu_packages/), and a [3.2.x PPA](https://launchpad.net/~directhex/+archive/monoxide) maintained by the Mono team.
 
+The regular expression backend is potentially not thread-safe (thanks to Martin Murray for pointing this out). A full rewrite of this backend is on the roadmap already due to some unexpected nondeterminism in the current implementation; we plan to fix this problem in that rewrite.
