# System Update
#
# This script does an in-place update of core system files including
# the `iqb` task runner and core system tasks
#
# By default, this script updates only the handful of core system
# files.  To update any other files you can run
#
#     iqb update <filenames>
#
# For example, to pull the updated .gitignore and .eslintrc:
#
#     iqb update .eslintrc .gitignore
