#
#   -r reinstalls all needed components before launching
#   -s runs in standalone (non-Plaform mode)
#   -p <planner_home_dir> sets the Planner home, defaults to current directory
#   -f <platform_home_dir> sets the Platform home, defaults to <current directory>/../fabric8-ui
#
# NOTE: this does not set any run mode or api url environment for non-standalone mode. If you
# need that, set it as usual before launching this script.
