+Usage: build_docker_image.sh [options] [-- [cmake_args]...]
+
+Available options:
+  General:
+    -h|--help               show this help message
+  Docker-specific:
+    -s|--source             image source dir (i.e. debian8, nvidia-cuda, etc)
+    -d|--docker-repository  docker repository for the image
+    -t|--docker-tag         docker tag for the image
+
+Required options: --source and --docker-repository.
+
+For example, running:
+$ build_docker_image.sh -s debian9 -d mydocker/debian9-clang -t latest
+will produce two docker images:
+    mydocker/debian9-clang-build:latest - an intermediate image used to compile
+      clang.
+    mydocker/clang-debian9:latest       - a small image with preinstalled clang.
+Please note that this example produces a not very useful installation, since it
+doesn't override CMake defaults, which produces a Debug and non-boostrapped
+version of clang.
