-b, --breakpoints Run the debugger at specific bytecode offsets (comma-separated).
Only available when compiled with VM debugging on
-d, --disassemble Disassemble the given bytecode file instead of executing it
-m, --mode Set the compilation mode. Acceptable values are 'debug' and
'release'
--warnings Turn warnings on/off (default: on). Acceptable values are
yes/on and no/off
--noWarn Disable a specific warning (for example, --noWarn unusedVariable)
