  18         When passing parameters,
  19         x:              means that a value should follow x
  20         y               means that 'y' is a flag, either on or off
  21         So, the string a:b:def means that we support up to
  22         5 parameters; two with values and three flags. The following
  23         should be valid:
  24
  25         script run parameters.lua -a 1 -blala -c -de
  26
  27         Notice two things:
  28         1. 'blala' works just like 'b lala', both set 'b' to 'lala'
  29         2. Flags can be put together, '-de' is the same as '-d -e'
  30         3. The format -b=lala is *not* supported
  31         4. The format b lala (without -) is *not* supported

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