# Create new wrapper for zephulor
#
# Usage: new_zephulor_wrapper <BINARY> [<BINARY_DIRECTORY>]
#    ex: new_zephulor_wrapper main maptool
#    ex: new_zephulor_wrapper zephulor
#
# Notes: - BINARY_DIRECTORY is optional, but if given,
#          it must be relative to ${GAMES_DATADIR}/${PN}, and
#          must be a subdir of ${GAMES_DATADIR}/${PN}
#        - you must NOT specify .py for BINARY
#        - wrapper's name is defined with the 3 first lines
#          of the function : warning : only one wrapper by subdir is allowed !
