It does not matter you do not have main function, just start debugging
whatever function you have e.g. by:
:step <yourFunctionName> <functionArg> ...
Setting breakpoints works too without main. Actually, I'm aware only
of one thing which does not work without main. It is :main command.
But that command does not seem to do much, looks like it only sets
program arguments and calls main.
