acid_io vs core_io vs core-error

A pared-down version of std::io usable with no_std

This is a copy of libstd::io with all the parts that don't work in core removed. Most importantly, it provides the Read and Write traits. This crate is (mostly) automatically generated from the rust git source. The version of the source that corresponds to your compiler version will be selected automatically by the build script.
