-**Help us help you.**
-
-If you are reporting a bug, include:
-
-* a Minimum Working Example without any dependencies (except libc) that shows
-  the issue and ideally reproduces in the Rust playground
-* the target triple - libc supports many targets and many APIs
-* instructions to reproduce, logs (e.g. build logs, links to Travis-CI logs,
-  uploads to github gists, etc.).
-
-If you are requesting a new API, include:
-
-* the target triple
-* link to the documentation of the API showing the type signatures, how to use
-  it, etc.
-
-In general, just please consider that the people who can help you are all very
-busy, they will be helping you in their free time, there are a lot of people in
-need of help so they need to prioritize to which issues they devote their free
-time, etc. So try to give most of the information upfront, be concise, show
-small self-contained examples (nobody has time to create a new cargo project,
-set up dependencies,...), etc. Help us help you.

-### Releasing your change to crates.io
+## Breaking change policy
+
+Sometimes an upstream adds a breaking change to their API e.g. removing outdated items,
+changing the type signature, etc. And we probably should follow that change to build the
+`libc` crate successfully. It's annoying to do the equivalent of semver-major versioning
+for each such change. Instead, we mark the item as deprecated and do the actual change
+after a certain period. The steps are:
+
+1. Add `#[deprecated(since = "", note="")]` attribute to the item.
+  - The `since` field should have a next version of `libc`
+    (e.g., if the current version is `0.2.1`, it should be `0.2.2`).
+  - The `note` field should have a reason to deprecate and a tracking issue to call for comments
+    (e.g., "We consider removing this as the upstream removed it.
+    If you're using it, please comment on #XXX").
+2. If we don't see any concerns for a while, do the change actually.

+## Releasing your change to crates.io
 
 Now that you've done the amazing job of landing your new API or your new
 platform in this crate, the next step is to get that sweet, sweet usage from
 crates.io! The only next step is to bump the version of libc and then publish
 it. If you'd like to get a release out ASAP you can follow these steps:
 
-1. Update the version number in `Cargo.toml`, you'll just be bumping the patch
-   version number.
-2. Run `cargo update` to regenerate the lockfile to encode your version bump in
-   the lock file. You may pull in some other updated dependencies, that's ok.

+// This module contains bindings to the native Haiku API. The Haiku API
+// originates from BeOS, and it was the original way to perform low level
+// system and IO operations. The POSIX API was in that era was like a
+// compatibility layer. In current Haiku development, both the POSIX API and
+// the Haiku API are considered to be co-equal status. However, they are not
+// integrated like they are on other UNIX platforms, which means that for many
+// low level concepts there are two versions, like processes (POSIX) and
+// teams (Haiku), or pthreads and native threads.
+//
+// Both the POSIX API and the Haiku API live in libroot.so, the library that is
+// linked to any binary by default.
+//
+// This file follows the Haiku API for Haiku R1 beta 2. It is organized by the
+// C/C++ header files in which the concepts can be found, while adhering to the
+// style guide for this crate.
+
+// Helper macro to generate u32 constants. The Haiku API uses (non-standard)
+// multi-character constants (like 'UPDA' or 'MSGM') to represent 32 bit
+// integer constants.
