-coreutils
-=========
+uutils coreutils
+================
+
+uutils is an attempt at writing universal (as in cross-platform) CLI
+utils in [Rust](http://rust-lang.org). This repo is to aggregate the GNU
+coreutils rewrites.
+
+Why?
+----
+
+Many GNU, linux and other utils are pretty awesome, and obviously
+[some](http://gnuwin32.sourceforge.net) [effort](http://unxutils.sourceforge.net)
+has been spent in the past to port them to windows. However those projects
+are either old, abandonned, hosted on CVS, written in platform-specific C, etc.
+
+Rust provides a good platform-agnostic way of writing systems utils that are easy
+to compile anywhere, and this is as good a way as any to try and learn it.
