i need a module for more involved command line parsing

[Skaperen]

now i really need to understand decorators and what they do.

Not really,there is no problem teaching someone Click that don't know what a decorator is.

i'm different than most. i need to understand what i am using/doing. and that needs to understand things as deep as possible. the more i understand it the more i can do with it.

so what does @my_decorator really do?

are decorators always functions? what if some arbitrary function is used?
