 # Redox C Library (relibc)

-relibc is a portable POSIX C standard library written in Rust. It is under heavy development, and currently supports Redox and Linux.
+relibc is a portable POSIX C standard library written in Rust and is under heavy development.

 The motivation for this project is twofold: Reduce issues that the Redox developers were having with [newlib](https://sourceware.org/newlib/), and create a safer alternative to a C standard library written in C. It is mainly designed to be used under Redox, as an alternative to newlib, but it also supports Linux system calls via the [sc](https://crates.io/crates/sc) crate.

+Currently Redox and Linux are supported.
