Dockerfile

# Builds a Docker image that has libxayagame (and all its dependencies)
# installed into /usr/local.  This can then be used as basis for images
# that build (and run) e.g. GSPs.

# Start by setting up a base image with all packages that we need
# both for the build but also in the final image.  These are the dependencies
# that are required as dev packages also for using libxayagame.
