# TODO: This bit is a little awful, and perhaps we should look at getting
#       rid of it at some point.
#
#       We want to unshallow the checkout and submodules to allow our build
#       process to have the full and complete git history for `git describe`
#       but that's really not the responsibility of the Dockerfile but actually
#       the CI system or whatever we're using.
#
#       To do this, we do a couple of things: Firstly, we fix the submodule
#       .git files to have a corrected path in them, and then we force the
#       .git/config to use http not ssh, and then we fetch and unshallow the
#       main repo and the submodules.
#
#       Leaving it in for now, but will look to remove in future.
#
#       I think this was mainly for DockerHub rather than Travis?
