{ hscloud, lib, pkgs, ... }:
# This supports building laserproxy in nix, which is used for deploying it to customs.
# This is mildly hacky and should be reworked to function for any hscloud bazel target
# in a more generic fashion.
#
# To build:
# ~/hscloud $ nix-build -A hswaw.laserproxy
pkgs.buildBazelPackage rec {
name = "laserproxy";
# Cleanup source tree to limit impact of unrelated changes to hscloud source
# tree on nix build cache. This should only pass over:
# //BUILD, //WORKSPACE, //.bazelrc
# //hscloud/go/**
# //hscloud/third_party/**
# //hscloud/devtools/gerrit/** (WORKSPACE reference)
# //hswaw/laserproxy/** (our build target)
