-/// Represents a set of characters / bytes that should be percent-encoded.
-///
-/// See [encode sets specification](http://url.spec.whatwg.org/#simple-encode-set).
-///
-/// Different characters need to be encoded in different parts of an URL.
-/// For example, a literal `?` question mark in an URL’s path would indicate
-/// the start of the query string.
-/// A question mark meant to be part of the path therefore needs to be percent-encoded.
-/// In the query string however, a question mark does not have any special meaning
-/// and does not need to be percent-encoded.
-///
-/// A few sets are defined in this module.
-/// Use the [`define_encode_set!`](../macro.define_encode_set!.html) macro to define different ones.

-/// Define a new struct
-/// that implements the [`EncodeSet`](percent_encoding/trait.EncodeSet.html) trait,
-/// for use in [`percent_decode()`](percent_encoding/fn.percent_encode.html)

-///
-/// Parameters are characters to include in the set in addition to those of the base set.
