I Can't Belive its not Docker

I can't belive its not Docker adds annotations to docker files that allow features not possible with docker alone.

Features

Including directories not in the build context

Add a #include <path_to_directory> <path_in_build_context> to a dockerfile to include the referenced directory in the build context at build time. The included directory does not have to be inside the main build context, it is copied into the build context at build time

Running scripts on the host machine prior to a build

Add #run <command> to run a script on the host machine in the build context before executing the dockerfile

Flags

Add #flags <list_of_flags> to provide modifiers to icbind. Supported flags are:

• nocontext -- Don't automatically copy the path into the build directory.
