%%% @doc
%%% The purpose of this command is to prepare a rebar3 project so that
%%% rebar3 understands that the dependencies are all already
%%% installed. If you want a hygienic build on nix then you must run
%%% this command before running rebar3. I suggest that you add a
%%% `Makefile` to your project and have the bootstrap command be a
%%% dependency of the build commands. See the nix documentation for
%%% more information.
%%%
%%% This command designed to have as few dependencies as possible so
%%% that it can be a dependency of root level packages like rebar3. To
%%% that end it does many things in a fairly simplistic way. That is
%%% by design.
%%%
%%% ### Assumptions
%%%
%%% This command makes the following assumptions:
%%%
%%% * It is run in a nix-shell or nix-build environment
%%% * that all dependencies have been added to the ERL_LIBS
