# This script is designed to facilitate in-tree development and testing
# by installing symlinks on your system which refer to in-tree helper
# utilities.  These helper utilities must be installed to in order to
# exercise all ZFS functionality.  By using symbolic links and keeping
# the scripts in-tree during development they can be easily modified
# and those changes tracked.
#
# Use the following configuration option to override the installation
# paths for these scripts.  The correct path is automatically set for
# most distributions but you can optionally set it for your environment.
