# either specific executables or the bin/ for certain gem(s), but
# incorporates the basicEnv as a requirement so that its $out is in our path.
# When stubbing the bins for a gem, we should use the gem expression
# directly, which means that basicEnv should somehow make it available.
# Different use cases should use different variations on this file, rather
# than the expression trying to deduce a use case.
# The basicEnv should be put into passthru so that e.g. nix-shell can use it.
