-# Libudev Rust Bindings
-
-The `libudev-sys` crate provides declarations and linkage for the `libudev` C library. Following the
-`*-sys` package conventions, the `libudev-sys` crate does not define higher-level abstractions over
-the native `libudev` library functions.
-
-## Dependencies
-In order to use the `libudev-sys` crate, you must have a Linux system with the `libudev` library
-installed where it can be found by `pkg-config`. To install `libudev` on Debian-based Linux
-distributions, execute the following command:
-
-```
-sudo apt-get install libudev-dev
-```
-
-`libudev` is a Linux-specific package. It is not available for Windows, OSX, or other operating
-systems.
-
-### Cross-Compiling
-To link to a cross-compiled version of the native `libudev` library, it's necessary to set several
-environment variables to configure `pkg-config` to work with a cross-compiler's sysroot. [Autotools
-Mythbuster](https://autotools.io/) has a good explanation of [supporting
-cross-compilation](https://autotools.io/pkgconfig/cross-compiling.html) with `pkg-config`.
-
-However, Rust's [`pkg-config` build helper](https://github.com/alexcrichton/pkg-config-rs) doesn't
-support calling a `$CHOST`-prefixed `pkg-config`. It will always call `pkg-config` without a prefix.
-To cross-compile `libudev-sys` with the `pkg-config` build helper, one must define the environment
-variables `PKG_CONFIG_DIR`, `PKG_CONFIG_LIBDIR`, and `PKG_CONFIG_SYSROOT_DIR` for the *default*
-`pkg-config`. It's also necessary to set `PKG_CONFIG_ALLOW_CROSS` to tell Rust's `pkg-config` helper
-that it's okay to proceed with a cross-compile.
-
-To adapt the `pkg-config` wrapper in the Autotools Mythbuster guide so that it works with Rust, one
-will end up with a script similar to the following:
-
-```sh
-#!/bin/sh
-
-SYSROOT=/build/root
-
-export PKG_CONFIG_DIR=
-export PKG_CONFIG_LIBDIR=${SYSROOT}/usr/lib/pkgconfig:${SYSROOT}/usr/share/pkgconfig
-export PKG_CONFIG_SYSROOT_DIR=${SYSROOT}
-export PKG_CONFIG_ALLOW_CROSS=1
-
-cargo build
-```
-
-## Usage
-Add `libudev-sys` as a dependency in `Cargo.toml`:
-
-```toml
-[dependencies]
-libudev-sys = "0.1.1"
-```
-
-Import the `libudev_sys` crate and use the functions as they're defined in the native `libudev`
-library. See the [`libudev` API documention](http://www.freedesktop.org/software/systemd/libudev/)
-for more usage information.
-
-```rust
-extern crate libudev_sys as ffi;
-```
-
-The `libudev-sys` build script detects the presence of native `libudev` functions and exports the
-functions found to exist. `libudev-sys` exports this information from its build script, which Cargo
-will provide to the build scripts of dependent packages in the form of environment variables:
-
-* `DEP_LIBUDEV_HWDB={true,false}`: The native `libudev` library has `udev_hwdb_*` functions. They will be
-  exported by `libudev-sys`.
-
-### Finding Help
-Since `libudev-sys` does nothing more than export symbols from the native `libudev` library, the
-best source for help is the information already available for the native `libudev`:
-
-* [API Documentation](http://www.freedesktop.org/software/systemd/libudev/)
