// SOFTWARE.
// WARNING: JSLint will hurt your feelings.
// JSLINT is a global function. It takes two parameters.
// var myResult = JSLINT(source, option);
// The first parameter is either a string or an array of strings. If it is a
// string, it will be split on '\n' or '\r'. If it is an array of strings, it
// is assumed that each string represents one line. The source can be a
// JavaScript text, or HTML text, or a JSON text, or a CSS text.
// The second parameter is an optional object of options that control the
// operation of JSLINT. Most of the options are booleans: They are all
// optional and have a default value of false. One of the options, predef,
// can be an array of names, which will be used to declare global variables,
// or an object whose keys are used as global names, with a boolean value
// that determines if they are assignable.
// If it checks out, JSLINT returns true. Otherwise, it returns false.
// If false, you can inspect JSLINT.errors to find out the problems.
// JSLINT.errors is an array of objects containing these properties:
// {
// line : The line (relative to 0) at which the lint was found
// character : The character (relative to 0) at which the lint was found
// reason : The problem
// evidence : The text line in which the problem occurred
// raw : The raw message before the details were inserted
// a : The first detail
// b : The second detail
// c : The third detail
// d : The fourth detail
// }
// If a stopping error was found, a null will be the last element of the
// JSLINT.errors array. A stopping error means that JSLint was not confident
// enough to continue. It does not necessarily mean that the error was
// especially heinous.
// You can request a Function Report, which shows all of the functions
// and the parameters and vars that they use. This can be used to find
// implied global variables and other problems. The report is in HTML and
// can be inserted in an HTML <body>.
// var myReport = JSLINT.report(errors_only);
// If errors_only is true, then the report will be limited to only errors.
// You can request a data structure that contains JSLint's results.
// var myData = JSLINT.data();
// It returns a structure with this form:
// {
// errors: [
// {
// line: NUMBER,
// character: NUMBER,
// reason: STRING,
// evidence: STRING
// }
// ],
// functions: [
// {
// name: STRING,
// line: NUMBER,
// last: NUMBER,
// params: [
// {
// string: STRING
// }
// ],
// closure: [
// STRING
// ],
// var: [
// STRING
// ],
// exception: [
// STRING
// ],
// outer: [
// STRING
// ],
// unused: [
// STRING
// ],
// undef: [
// STRING
// ],
// global: [
// STRING
// ],
// label: [
// STRING
// ]
// }
// ],
// globals: [
// STRING
// ],
// member: {
// STRING: NUMBER
// },
// urls: [
// STRING
// ],
// json: BOOLEAN
// }
// Empty arrays will not be included.
// You can obtain the parse tree that JSLint constructed while parsing. The
// latest tree is kept in JSLINT.tree. A nice stringication can be produced
// with
// JSON.stringify(JSLINT.tree, [
// 'string', 'arity', 'name', 'first',
// 'second', 'third', 'block', 'else'
// ], 4));
// JSLint provides three directives. They look like slashstar comments, and
// allow for setting options, declaring global variables, and establishing a
// set of allowed property names.
// These directives respect function scope.
// The jslint directive is a special comment that can set one or more options.
// The current option set is
// adsafe true, if ADsafe rules should be enforced
// bitwise true, if bitwise operators should be allowed
// browser true, if the standard browser globals should be predefined
// cap true, if upper case HTML should be allowed
// confusion true, if types can be used inconsistently
// 'continue' true, if the continuation statement should be tolerated
// css true, if CSS workarounds should be tolerated
// debug true, if debugger statements should be allowed
// devel true, if logging should be allowed (console, alert, etc.)
// eqeq true, if == should be allowed
// es5 true, if ES5 syntax should be allowed
// evil true, if eval should be allowed
// forin true, if for in statements need not filter
// fragment true, if HTML fragments should be allowed
// indent the indentation factor
// maxerr the maximum number of errors to allow
// maxlen the maximum length of a source line
// newcap true, if constructor names capitalization is ignored
// node true, if Node.js globals should be predefined
// nomen true, if names may have dangling _
// on true, if HTML event handlers should be allowed
// passfail true, if the scan should stop on first error
// plusplus true, if increment/decrement should be allowed
// properties true, if all property names must be declared with /*properties*/
// regexp true, if the . should be allowed in regexp literals
// rhino true, if the Rhino environment globals should be predefined
// undef true, if variables can be declared out of order
// unparam true, if unused parameters should be tolerated
// safe true, if use of some browser features should be restricted
// sloppy true, if the 'use strict'; pragma is optional
// sub true, if all forms of subscript notation are tolerated
// vars true, if multiple var statements per function should be allowed
// white true, if sloppy whitespace is tolerated
// widget true if the Yahoo Widgets globals should be predefined
// windows true, if MS Windows-specific globals should be predefined
// For example:
/*jslint
evil: true, nomen: true, regexp: true
*/
// The properties directive declares an exclusive list of property names.
// Any properties named in the program that are not in the list will
// produce a warning.
// For example:
/*properties
