 #  This script vendors the Web Console source files into bindata.go files that can be built into the openshift binary.
 #
 #  Accepted environment variables are:
 #   - GIT_REF:           specifies which branch / tag of the web console to vendor. If set, then any untracked/uncommitted changes
 #                        will cause the script to exit with an error. If not set then the current working state of the web console
 #                        directory will be used.
 #   - CONSOLE_REPO_PATH: specifies a directory path to look for the web console repo.  If not set it is assumed to be
 #                        a sibling to this repository.
