+# A simple script to run commands (e.g. build commands) in a Docker container.
+# It can be used for testing on platforms different from the host. For example,
+# the command
+# 
+# ./container-run.sh arm ./build test
+#
+# builds nissy and runs the unit tests in an ARM container.
+#
+# The containers are based on Alpine Linux and the contain the necessary tools
+# to build the main library and the C++ and Python examples. They DO NOT
+# contain the emscripten compiler, so they cannot be used to build the web
+# version (e.g. ./build web or ./buidl webtest).
+# The images are given a tag starting with 'localhost/nissy/'.
+#
+# See below for a list of options.
