+ JSHINT is a global function. It takes two parameters.
+
+     var myResult = JSHINT(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 a JSON text.
+
+ The second parameter is an optional object of options which control the
+ operation of JSHINT. 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, JSHINT returns true. Otherwise, it returns false.
+
+ If false, you can inspect JSHINT.errors to find out the problems.
+ JSHINT.errors is an array of objects containing these members:
+
+ {
+     line      : The line (relative to 1) at which the lint was found
+     character : The character (relative to 1) 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 fatal error was found, a null will be the last element of the
+ JSHINT.errors array.
+
+ You can request a data structure which contains JSHint's results.
+
+     var myData = JSHINT.data();
+
+ It returns a structure with this form:
+
+ {
+     errors: [
+         {
+             line: NUMBER,
+             character: NUMBER,
