 This module provides utilities for dealing with query strings.
 It provides the following methods:
 
-## querystring.stringify(obj[, sep][, eq][, options])
-
-Serialize an object to a query string.
-Optionally override the default separator (`'&'`) and assignment (`'='`)
-characters.
-
-Options object may contain `encodeURIComponent` property (`querystring.escape` by default),
-it can be used to encode string with `non-utf8` encoding if necessary.
-
-Example:
-
-    querystring.stringify({ foo: 'bar', baz: ['qux', 'quux'], corge: '' })
-    // returns
-    'foo=bar&baz=qux&baz=quux&corge='
-
-    querystring.stringify({foo: 'bar', baz: 'qux'}, ';', ':')
-    // returns
-    'foo:bar;baz:qux'
+## querystring.escape
 
-    // Suppose gbkEncodeURIComponent function already exists,
-    // it can encode string with `gbk` encoding
-    querystring.stringify({ w: '中文', foo: 'bar' }, null, null,
-      { encodeURIComponent: gbkEncodeURIComponent })
-    // returns
-    'w=%D6%D0%CE%C4&foo=bar'
