That's right. If you have a path to a directory and want to create the
entire thing, use flags = 3. 

If you have a path to a file and just want to create the directory leading 
up to that file (or confirm it exists and is a directory), use flags = 2.

If you want to use it as just "mkdir", flags = 1.

Then add the verbose flag if you want it to say what it's doing.

If it's a path to a file, yes. If it's not a path to a file, feed it just
the path and use flags=3.

I don't understand. Could you explain your use case?

Mostly likely I didn't document it well enough, but I may be missing
something...
