+# Dockerfile-based build for Swift Static Linux SDK
+
+## What is this?
+
+This is a Dockerfile-based build set-up for the Swift Static Linux SDK.
+
+To use it, you need to build the Docker image with
+
+```shell
+$ docker build -t static-swift-linux .
+```
+
+then you can check-out the sources somewhere using
+
+```shell
+$ scripts/fetch-source.sh --clone-with-ssh --source-dir /path/to/source
+```
+
+and finally use the Docker image to do your build
+
+```shell
+$ mkdir /path/to/products
+$ docker run -it --rm  \
+             -v /path/to/source:/source \
+             -v /path/to/products:/products \
+             static-swift-linux \
+             /scripts/build.sh --source-dir /source --products-dir /products
+```
+
+The artifact bundle should appear at `/path/to/products`.
+
+The `scripts/build.sh` script has a number of options you may wish to
+investigate.  Similarly with the `scripts/fetch-source.sh` script.

+What is this?
+=============
+
+Musl doesn't have fts in its libc.  Alpine and other Musl-based
+distributions typically provide an fts implementation separately,
+using a derivative of NetBSD's fts, which is what you'll find in this
+directory.
+
+Typically they use the one from https://github.com/void-linux/musl-fts
+but that uses GNU autotools and annoyingly they haven't checked in the
+generated configure script.  Not that it actually *needs* a configure
+script, because they know what C library they're using already.
+
+Anyway, I grabbed the fts sources from there and chucked them in this
+directory along with a CMakeLists.txt that lets us build them with
+CMake.
