It'd be nice to manually print usage

[turboladen]

In some cases (i.e. if an argument is the correct type but maybe isn't exactly desirable), it'd be nice to short-circuit the app and manually print the usage. I didn't see a way to do this in the docs.

I'm using 0.1.3.

Do you mean that, on top of validating the type of the argument, there should be a way to add a function that further checks if whether or not the argument is valid? I'm looking for making my first open source contribution, so I'm thinking about adding this feature

Mm, I might’ve missed this in the docs somewhere, but I mainly just wanted a way to manually print to STDOUT the usage info.

Ok. Maybe I could add a function that you can manually call to print usage in your code then. What do you think @benbrittain ? Any recommendation as to how this should be done ? = ]
