	When passing parameters, 
	x:		means that a value should follow x
	y		means that 'y' is a flag, either on or off
	So, the string a:b:def means that we support up to 
	5 parameters; two with values and three flags. The following 
	should be valid: 

	script run parameters.lua -a 1 -blala -c -de

	Notice two things:
	1. 'blala' works just like 'b lala', both set 'b' to 'lala'
	2. Flags can be put together, '-de' is the same as '-d -e'
	3. The format -b=lala is *not* supported
	4. The format b lala (without -) is *not* supported

In the future, we may implement so that scripts are invoked directly 
into a 'main' function, instead of being executed blindly. For future
compatibility, I have done so, but I invoke my main from here.
