# Test of duplicates in autocli expansion. 
# Regression of issues:
#  keys: https://github.com/clicon/clixon/issues/301
#  reftree: https://github.com/clicon/cligen/issues/73
# Duplicates can happen in expansion in autocli of unions and treerefs(@) where the same
# command occurs multiple times, ie "merging" does not work in some cases
# An effect is also that next level expansion does not work, ie "after" the command

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