# The test uses a backend that logs to a file and a netconf client to push
# changes. The main example backend plugin logs to the file, and the test
# verifies the logs.
# The yang is a list with three members, so that you can do add/delete/change
# in a single go.

# Magic line must be first in script (see README.md)
