target.sh

# target.sh -- sourced by the .sh wrappers, right after they pick $PYTHON.
#
# Runs the wrapper on one or both OBP targets (see obp_target.py):
#
#   ./some_script.sh ...                   LOCAL (the default)
#   ./some_script.sh --target=PROD ...     PROD only
#   ./some_script.sh --target=BOTH ...     LOCAL, then PROD if LOCAL succeeded
#   OBP_TARGET=BOTH ./some_script.sh ...   the same, from the environment
#
# It re-runs the calling script once per target with OBP_TARGET set to LOCAL or
# PROD, then exits with the first failure's code (or 0). Wrappers called from such
# a run (as recreate_dynamic_entities.sh calls others) inherit its target and run
# just once, so they don't loop again.
