## Installing from Source
The Rust build system uses a Python script called `x.py` to build the compiler,
which manages the bootstrapping process. It lives in the root of the project.

### Building on Windows
There are two prominent ABIs in use on Windows: the native (MSVC) ABI used by
Visual Studio, and the GNU ABI used by the GCC toolchain. Which version of Rust
you need depends largely on what C/C++ libraries you want to interoperate with:
for interop with software produced by Visual Studio use the MSVC build of Rust;
for interop with GNU software built using the MinGW/MSYS2 toolchain use the GNU

Right now, building Rust only works with some known versions of Visual Studio. If
you have a more recent version installed and the build system doesn't understand,
you may need to force rustbuild to use an older version. This can be done
by manually calling the appropriate vcvars file before running the bootstrap.

Since the Rust compiler is written in Rust, it must be built by a
precompiled "snapshot" version of itself (made in an earlier stage of
development). As such, source builds require a connection to the Internet, to
development). As such, source builds require an Internet connection to
fetch snapshots, and an OS that can execute the available snapshot binaries.
Snapshot binaries are currently built and tested on several platforms:
