// The creation of this script is to work around the issue of having to run a npm postinstall step
// only within the context of a GPII development environment.
// This script detects the existence of a resolvable browserify module which is ordinarily only pulled in as a devDependency.
// If the directory is present, this script browserifies some node js scripts that are used by some
// in-browser tests, e.g. all tests located at %gpii-universal/gpii/node_modules/gpii-oauth2/gpii-oauth2-authz-server/test/html/.
// Otherwise, skip the browserifying and exit quietly.
