-Test Infrastructure
-===================
-
-The ci directory contains scripts that aid in the testing of nix both
-in our continuous integration environment (Travis CI) but also for
-developers working locally.
-
-Nix interfaces very directly with the underlying platform (usually via
-libc) and changes need to be tested on a large number of platforms to
-avoid problems.
-
-Running Tests For Host Architecture
------------------------------------
-
-Running the tests for one's host architecture can be done by simply
-doing the following:
-
-    $ cargo test
-
-Running Tests Against All Architectures/Versions
-------------------------------------------------
-
-Testing for other architectures is more involved.  Currently,
-developers may run tests against several architectures and versions of
-rust by running the `ci/run-all.sh` script.  This scripts requires
-that docker be set up.  This will take some time:
-
-    $ ci/run-all.sh
-
-The list of versions and architectures tested by this can be
-determined by looking at the contents of the script.  The docker image
-used is [posborne/rust-cross][posborne/rust-cross].
-
-[posborne/rust-cross]: https://github.com/rust-embedded/docker-rust-cross
-
-Running Test for Specific Architectures/Versions
-------------------------------------------------
-
-Suppose we have a failing test with Rust 1.7 on the raspberry pi.  In
-that case, we can run the following:
-
-    $ DOCKER_IMAGE=posborne/rust-cross:arm \
-          RUST_VERSION=1.7.0 \
-          RUST_TARGET=arm-unknown-linux-gnueabihf ci/run-docker.sh
-
-Currently, the docker images only support Rust 1.7.  To get a better
-idea of combinations that might work, look at the contents of the
-[travis configuration](../.travis.yml) or [run-all.sh](run-all.sh).
