# Normally, this node2nix invocation would be sufficient:
# exec node2nix --input node-packages.json --composition composition.nix
#
# But pump.io soft-depends on extra modules, which have to be *inside*
# its own node_modules, not beside them.
#
# So we hack these extra deps into package.json and feed that into
# node2nix.
#
# Also jshon does funny things with slashes in strings, which can be
# fixed with sed.
