Reorganize README to make it more clear.

This also adds a note about required memory usage and instructions for
building from Git.

This is a compiler for Rust, including standard libraries, tools and
documentation.
## Quick Start
## Installation
### Windows
The Rust compiler currently must be built from a [tarball], unless you
are on Windows, in which case using the [installer][win-exe] is
recommended.
1. Download and use the [installer][win-exe].
2. Read the [tutorial].
2. Enjoy!
Since the Rust compiler is written in Rust, it must be built by
a precompiled "snapshot" version of itself (made in an earlier state
of development). As such, source builds require a connection to
the Internet, to fetch snapshots, and an OS that can execute the
available snapshot binaries.
> ***Note:*** Windows users should read the detailed
> [getting started][wiki-start] notes on the wiki. Even when using
> the binary installer the Windows build requires a MinGW installation,
> the precise details of which are not discussed here.

[wiki-start]: https://github.com/mozilla/rust/wiki/Note-getting-started-developing-Rust
[win-exe]: http://static.rust-lang.org/dist/rust-0.7-install.exe
### Linux / OS X
1. Install the prerequisites (if not already installed)
* g++ 4.4 or clang++ 3.x
* python 2.6 or later (but not 3.x)
* perl 5.0 or later
* gnu make 3.81 or later
* curl
2. Download and build Rust
You can either download a [tarball] or build directly from the [repo].
To build from the [tarball] do:
$ curl -O http://static.rust-lang.org/dist/rust-0.7.tar.gz
$ tar -xzf rust-0.7.tar.gz
$ cd rust-0.7
Or to build from the [repo] do:
$ git clone https://github.com/mozilla/rust.git
$ cd rust
Now that you have Rust's source code, you can configure and build it:
$ ./configure
$ make && make install
You may need to use `sudo make install` if you do not normally have
permission to modify the destination directory. The install locations can
be adjusted by passing a `--prefix` argument to `configure`. Various other
options are also supported, pass `--help` for more information on them.
When complete, `make install` will place several programs into
`/usr/local/bin`: `rustc`, the Rust compiler; `rustdoc`, the
API-documentation tool, and `rustpkg`, the Rust package manager and build
system.

Snapshot binaries are currently built and tested on several platforms:

You may find that other platforms work, but these are our "tier 1"
supported build environments that are most likely to work.

Rust currently needs about 1.8G of RAM to build without swapping; if it hits
swap, it will take a very long time to build.
To build from source you will also need the following prerequisite
packages:
There is lots more documentation in the [wiki].
* g++ 4.4 or clang++ 3.x
* python 2.6 or later (but not 3.x)
* perl 5.0 or later
* gnu make 3.81 or later
* curl
Assuming you're on a relatively modern *nix system and have met the
prerequisites, something along these lines should work.
$ curl -O http://static.rust-lang.org/dist/rust-0.7.tar.gz
$ tar -xzf rust-0.7.tar.gz
$ cd rust-0.7
$ ./configure
$ make && make install
