+winapi-util
+===========
+This crate provides a smattering of safe wrappers around various parts of the
+[winapi](https://crates.io/crates/winapi) crate.
+
+[![Build status](https://github.com/BurntSushi/winapi-util/workflows/ci/badge.svg)](https://github.com/BurntSushi/winapi-util/actions)
+[![](http://meritbadge.herokuapp.com/winapi-util)](https://crates.io/crates/winapi-util)
+
+Dual-licensed under MIT or the [UNLICENSE](http://unlicense.org).
+
+
+### Documentation
+
+https://docs.rs/winapi-util
+
+
+### Usage
+
+Add this to your `Cargo.toml`:
+
+```toml
+[dependencies]
+winapi-util = "0.1"
+```
+
+
+### Notes
+
+This crate was born out of frustration with having to write lots of little
+ffi utility bindings in a variety of crates in order to get Windows support.
+Eventually, I started needing to copy & paste a lot of those utility routines.
+Since they are utility routines, they often don't make sense to expose directly
+in the crate in which they are defined. Instead of continuing this process,
+I decided to make a crate instead.
+
+Normally, I'm not a huge fan of "utility" crates like this that don't have a
+well defined scope, but this is primarily a practical endeavor to make it
+easier to isolate Windows specific ffi code.
+
+While I don't have a long term vision for this crate, I will welcome additional
+PRs that add more high level routines/types on an as-needed basis.
+
+**WARNING:** I am not a Windows developer, so extra review to make sure I've
+got things right is most appreciated.
+
+
+### Minimum Rust version policy
+
+This crate's minimum supported `rustc` version is `1.34.0`.
+
+The current policy is that the minimum Rust version required to use this crate
+can be increased in non-breaking version updates. For example, if `crate 1.0`
+requires Rust 1.20.0, then `crate 1.0.z` for all values of `z` will also
+require Rust 1.20.0 or newer. However, `crate 1.y` for `y > 0` may require a
+newer minimum version of Rust.
+
+In general, this crate will be conservative with respect to the minimum
+supported version of Rust.

+/*!
+This crate provides a smattering of safe routines for parts of winapi. The
+primary purpose of this crate is to serve as a dumping ground for various
+utility functions that make interactions with winapi safe. This permits the
+centralization of `unsafe` when dealing with Windows APIs, and thus makes it
+easier to audit.
+
+A key abstraction in this crate is the combination of the
+[`Handle`](struct.Handle.html)
+and
+[`HandleRef`](struct.HandleRef.html)
+types. Both represent a valid Windows handle to an I/O-like object, where
+`Handle` is owned (the resource is closed when the handle is dropped) and
+`HandleRef` is borrowed (the resource is not closed when the handle is
+dropped). Many of the routines in this crate work on handles and accept
+anything that can be safely converted into a `HandleRef`. This includes
+standard library types such as `File`, `Stdin`, `Stdout` and `Stderr`.
+
+Note that this crate is completely empty on non-Windows platforms.
