+
+INTRODUCTION
+------------
+
+The Chaos tool suite (ctools) module is primarily a set of APIs and tools to
+improve the developer experience. It also contains a module called the Page
+Manager whose job is to manage pages. In particular it manages panel pages, but
+as it grows it will be able to manage far more than just Panels.
+
+The Chaos Tool Suite (ctools) is a series of tools that makes code readily
+available for developers and creates libraries for other modules to use. Modules
+that use ctools include Views and Panels.
+
+End users will use ctools as underlying user interface libraries when operating
+Views and Panels modules and will not need to explore further (ctools is geared
+more toward developer usage). Developers will use the module differently and
+work more with the tools provided.
+
+For the moment, it includes the following tools:
+
+ * Plugins -- tools to make it easy for modules to let other modules implement
+ plugins from .inc files.
+ * Exportables -- tools to make it easier for modules to have objects that live
+ in database or live in code, such as 'default views'.
+ * AJAX responder -- tools to make it easier for the server to handle AJAX
+ requests and tell the client what to do with them.
+ * Form tools -- tools to make it easier for forms to deal with AJAX.
+ * Object caching -- tool to make it easier to edit an object across multiple
+ page requests and cache the editing work.
+ * Contexts -- the notion of wrapping objects in a unified wrapper and providing
+ an API to create and accept these contexts as input.
+ * Modal dialog -- tool to make it simple to put a form in a modal dialog.
+ * Dependent -- a simple form widget to make form items appear and disappear
+ based upon the selections in another item.
+ * Content -- pluggable content types used as panes in Panels and other modules
+ like Dashboard.
+ * Form wizard -- an API to make multi-step forms much easier.
+ * CSS tools -- tools to cache and sanitize CSS easily to make user-input CSS
+ safe.
+
+ * For a full description of the module visit:
+ https://www.drupal.org/project/ctools
+
+ * To submit bug reports and feature suggestions, or to track changes visit:
+ https://www.drupal.org/project/issues/ctools
+
+
+REQUIREMENTS
+------------
+
+This module requires no modules outside of Drupal core.
+
+
+RECOMMENDED MODULES
+-------------------
+
+The Advanced help module provides extended documentation. Once enabled,
+navigate to Administration > Advanced Help and select the Chaos tools link to
+view documentation.
+
+ * Advanced help - https://www.drupal.org/project/advanced_help
+
+
+INSTALLATION
+------------
+
+ * Install the Chaos tool suite module as you would normally install a
+ contributed Drupal module. Visit https://www.drupal.org/node/895232 for
+ further information.

-NAME
- ctools_math_expr - safely evaluate math expressions
-
-SYNOPSIS
- include('ctools_math_expr.class.php');
- $m = new ctools_math_expr;
- // basic evaluation:
- $result = $m->evaluate('2+2');
- // supports: order of operation; parentheses; negation; built-in functions
- $result = $m->evaluate('-8(5/2)^2*(1-sqrt(4))-8');
- // create your own variables
- $m->evaluate('a = e^(ln(pi))');
- // or functions
- $m->evaluate('f(x,y) = x^2 + y^2 - 2x*y + 1');
- // and then use them
- $result = $m->evaluate('3*f(42,a)');
-
-DESCRIPTION
- Use the ctools_math_expr class when you want to evaluate mathematical expressions
- from untrusted sources. You can define your own variables and functions,
- which are stored in the object. Try it, it's fun!
-
-METHODS
- $m->evalute($expr)
- Evaluates the expression and returns the result. If an error occurs,
- prints a warning and returns false. If $expr is a function assignment,
- returns true on success.
-
- $m->e($expr)
- A synonym for $m->evaluate().
-
- $m->vars()
- Returns an associative array of all user-defined variables and values.
-
- $m->funcs()
- Returns an array of all user-defined functions.
-
-PARAMETERS
- $m->suppress_errors
- Set to true to turn off warnings when evaluating expressions
-
- $m->last_error
- If the last evaluation failed, contains a string describing the error.
- (Useful when suppress_errors is on).
