//   - how many arguments the directive can take
//   - whether or not it is a block directive
//   - whether this is a flag (takes one argument that's either "on" or "off")
//   - which contexts it's allowed to be in
//
// Since some directives can have different behaviors in different contexts, we
//   use lists of bit masks, each describing a valid way to use the directive.

//   nginx were taken directively from the source code. In fact, the variable
//   names for the bit masks defined above were taken from the nginx source code.
//
// Definitions for directives that're only available for nginx+ were inferred
//   from the documentation at http://nginx.org/en/docs/.
