# 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.
