This is a preliminary version of the Rust compiler, libraries and tools

Source layout:

rustc/             The self-hosted compiler

libcore/           The core library (imported and linked by default)
libstd/            The standard library (slightly more peripheral code)
libsyntax/         The Rust parser and pretty-printer

rt/                The runtime system
rt/rust_*.cpp      - The majority of the runtime services
rt/isaac           - The PRNG used for pseudo-random choices in the runtime
rt/bigint          - The bigint library used for the 'big' type
rt/uthash          - Small hashtable-and-list library for C, used in runtime
rt/sync            - Concurrency utils
rt/util            - Small utility classes for the runtime.
rt/vg              - Valgrind headers
rt/msvc            - MSVC support

test/              Testsuite
test/compile-fail  - Tests that should fail to compile
test/run-fail      - Tests that should compile, run and fail
test/run-pass      - Tests that should compile, run and succeed
test/bench         - Benchmarks and miscellanea
test/pretty        - Pretty-printer tests
test/auxiliary     - Dependencies of tests

compiletest/       The test runner

cargo/             The package manager

rusti/             The JIT REPL

rustdoc/           The Rust API documentation tool

llvm/              The LLVM submodule

libuv/             The libuv submodule

rustllvm/          LLVM support code

fuzzer/            A collection of fuzz testers

etc/               Scripts, editor support, misc
