#    Description:
#      This file implements a script which, when run from a project
#      build directory (either disparate or colocated with the
#      source), will attempt to clean the build directory, rebootstrap
#      the package, and then rerun the configuration script for the
#      package with the provided arguments.
#
#      This script is particularly useful when you are changing the
#      configuration script and testing those changes.
#

# Bring the package build back to a pristine state.
