+// jslint(source, option_object, global_array) is a function that takes 3
+// arguments. The second two arguments are optional.
+
+//      source          A text to analyze, a string or an array of strings.
+//      option_object   An object whose keys correspond to option names.
+//      global_array    An array of strings containing global variables that
+//                      the file is allowed readonly access.
+
+// jslint returns an object containing its results. The object contains a lot
+// of valuable information. It can be used to generate reports. The object
+// contains:
+
+//      directives: an array of directive comment tokens.
+//      edition: the version of JSLint that did the analysis.
+//      exports: the names exported from the module.
+//      froms: an array of strings representing each of the imports.
+//      functions: an array of objects that represent all of the functions
+//              declared in the file.
+//      global: an object representing the global object. Its .context property
+//              is an object containing a property for each global variable.
+//      id: "(JSLint)"
+//      json: true if the file is a JSON text.
+//      lines: an array of strings, the source.
+//      module: true if an import or export statement was used.
+//      ok: true if no warnings were generated. This is what you want.
+//      option: the option argument.
+//      property: a property object.
+//      stop: true if JSLint was unable to finish. You don't want this.
+//      tokens: an array of objects representing the tokens in the file.
+//      tree: the token objects arranged in a tree.
+//      warnings: an array of warning objects. A warning object can contain:
+//          name: "JSLintError"
+//          column: A column number in the file.
+//          line: A line number in the file.
+//          code: A warning code string.
+//          message: The warning message string.
+//          a: Exhibit A.
+//          b: Exhibit B.
+//          c: Exhibit C.
+//          d: Exhibit D.
+
+// jslint works in several phases. In any of these phases, errors might be
+// found. Sometimes JSLint is able to recover from an error and continue
+// parsing. In some cases, it cannot and will stop early. If that should happen,
+// repair your code and try again.
+
+// Phases:
+
+//      1. If the source is a single string, split it into an array of strings.
+//      2. Turn the source into an array of tokens.
+//      3. Furcate the tokens into a parse tree.
+//      4. Walk the tree, traversing all of the nodes of the tree. It is a
+//          recursive traversal. Each node may be processed on the way down
+//          (preaction) and on the way up (postaction).
+//      5. Check the whitespace between the tokens.
+
+// jslint can also examine JSON text. It decides that a file is JSON text if
+// the first token is "[" or "{". Processing of JSON text is much simpler than
+// the processing of JavaScript programs. Only the first three phases are
+// required.
+
+// WARNING: JSLint will hurt your feelings.
