-/**
- * @file
- * Action definition example module.
- *
- * Triggers and actions are a matched pair of Drupal features allowing some
- * Drupal programming without using PHP. Using the appropriate action in a
- * specific event, a site administrator can add new functionality.
- * Examples are:
- *  - Send an email after a node is published or edited.
- *  - Display a message after a user has logged in.
- *  - Display a message and send an email after a node has been deleted.
- *
- * A trigger is a special function which can enqueue actions. The trigger module
- * provides the interface allowing us to associate certain actions with certain
- * triggers.
- *
- * Actions are the functions designed to be run by triggers.
- *
- * A trigger should build the appropriate context for the action to be fired.
- * Actions are very often grouped by functionality: examples are 'user', 'node',
- * 'taxonomy'. When actions are grouped it is because they expect the same
- * arguments. This way, you can enqueue as many actions understanding the 'user'
- * object as you want.
- *
- * Not all actions can be used in all triggers because they require different
- * contexts. But some actions are generic enough that they do not require
- * special objects in their contexts, and so can be used on every available
- * trigger. This 'group' type is used by actions to be available for this
- * trigger.
- *
- * What are good candidates to be triggers? Any function can be a trigger, as
- * long as it has the code to call the enqueued actions, but to make Drupal
- * more extensible, you will find hooks (from Drupal and contributed modules)
- * very good candidates. A trigger should build the arguments, ask for enqueued
- * actions and run them. You may define a function being a trigger, and run it
- * through a button in the front page, or you may prepare a trigger for a hook,
- * and everytime that hook is fired, your trigger will be.
- *
- * What are good candidates to be actions? any function is a possible action,
- * the only problem is finding a trigger able to run it.
- *
- * This module describes how to create actions for Drupal. In this
- * example we are providing three actions:
- *
- * - A generic action that can be used in any trigger, which is the most
- *   basic example of an action.
- *
- * - An action which which extends the capabilities of User triggers, even if
- *   associated with node or comment events.
- *
- * - An action which extends the capabilities of node triggers, but limited
- *   to certain events only, and using a customizable option.
- *
- * See:
- *
- * @todo this is a drupal 6 link
- * @link http://drupal.org/node/172152 Writing Actions @endlink
- *
- * @todo this is a drupal 6 link
- * @link http://drupal.org/node/199254 Triggers and Actions in Drupal 7 @endlink
- *
- * @see hook_action_info()
- * In addition, the @link trigger_example.module Trigger Example @endlink
- * provides detailed information on how to create a trigger.
- */
-
-/**
- * Implements hook_action_info().
- *
- * We call hook_action_info when we are defining the actions we provide.
- * Actions are the actions fired by the associated triggers. In this example,
- * we are registering our three new actions, providing the unique name (using
- * Drupal's convention modulename_description_action), an easy to understand
- * description of what the action does, the 'object' expected by this action
- * (default options from core are node, user, comment and system, however other
- * trigger modules may declare new object types), which are the triggers allowed
- * to use these action, and if some customization is available. Please, note
- * that the function name is not required to finish as _action to be declared as
- * a Drupal action, and that only information provided by hook_trigger_info()
- * will be considered for valid actions creation.
- *
- * These are the actions being provided in hook_action_info()
- *
- * - action_example_basic_action: this action is a dummy function which can be
- *   used by any trigger. The label describes that the action will do nothing,
- *   but is enough for a basic example. Type is set to system, so users will not
- *   be confused about the scope of this action (expecting a node, user, or any
- *   other object). This action is not configurable, and will appear as
- *   available in the list of action under the menu entry:
- *   'admin/config/system/actions.
- * - action_example_unblock_user_action: Unblocks a user.
- * - action_example_node_sticky_action: This action is a complex action that is
- *   only available to Node type triggers, and can only be associated with the
- *   events node presave, node insert and node update. The action does not
- *   exist by default and it has to be created by user configuration. This makes
- *   it an "advanced action" in Drupal, so-called because it requires
- *   configuration or customization.
- *   In this example action, the action will promote nodes and make them sticky
- *   during presave, insert, or update, but only for particular users. As an
- *   advanced action, it first needs to be created in the actions management
- *   page (admin/config/system/actions). At the bottom of that page a selection
- *   list shows a list of advanced actions that will includes the option
- *   'Promote to frontpage and sticky on top any content created by :'
- *   Selecting this option and clicking the 'Create' button, a configuration
- *   form will ask for an author name. When this action is associated to any
- *   of the possible Node trigger events, it will only be effective if the
- *   author of the content matches the author configured by the action.
- *
- * @return
- *   An associative array of action descriptions. The keys of the array
- *   are the names of the action functions, and each corresponding value
- *   is an associative array with the following key-value pairs:
- *   - 'type': The type of object this action acts upon. Core actions have types
- *     'node', 'user', 'comment', and 'system', but additional types can be
- *     used, as long as the trigger and action agree on them.
- *   - 'label': The human-readable name of the action, which should be passed
- *     through the t() function for translation.
- *   - 'configurable': If FALSE, then the action doesn't require any extra
- *     configuration. If TRUE, then your module must define a form function with
- *     the same name as the action function with '_form' appended (e.g., the
- *     form for 'node_assign_owner_action' is 'node_assign_owner_action_form'.)
- *     This function takes $context as its only parameter, and is paired with
- *     the usual _submit function, and possibly an _validate function.
- *   - 'triggers': An array of the triggers that can trigger this
- *     action. For example: array('node_insert', 'user_update'). You can also
- *     declare support for any trigger by returning array('any') for this value.
- *   - 'behavior': (optional) A machine-readable array of behaviors of this
- *     action, used to signal additionally required actions that may need to be
- *     triggered. Currently recognized behaviors by Trigger module:
- *     - 'changes_property': If an action with this behavior is assigned to a
- *       trigger other than a "presave" hook, any save actions also assigned to
- *       this trigger are moved later in the list. If no save action is present,
- *       one will be added.
- *       Modules that are processing actions (like Trigger module) should take
- *       special care in the "presave" hook, in which case a dependent "save"
- *       action should NOT be invoked.
- *
- * See hook_action_info().

- *
- * In Drupal 7 and forward, the usage of db_query()

- * (Note that drupal_write_record() is also deprecated.)
- *
- * db_insert() example:
- * @code
- *   // INSERT INTO {dbtng_example} (name, surname) VALUES('John, 'Doe')
- *   db_insert('dbtng_example')
- *     ->fields(array('name' => 'John', 'surname' => 'Doe'))

- * some context information as to where the mail request came from.

- * Example stream wrapper class to handle session:// streams.
- * This is just an example, as it could have horrible results if much
- * information were placed in the $_SESSION variable. However, it does
- * demonstrate both the read and write implementation of a stream wrapper.
- *
- * A "stream" is an important Unix concept for the reading and writing of
- * files and other devices. Reading or writing a "stream" just means that you
- * open some device, file, internet site, or whatever, and you don't have to
- * know at all what it is. All the functions that deal with it are the same.
- * You can read/write more from/to the stream, seek a position in the stream,
- * or anything else without the code that does it even knowing what kind
- * of device it is talking to. This Unix idea is extended into PHP's
- * mindset.
- *
- * The idea of "stream wrapper" is that this can be extended indefinitely.
- * The classic example is HTTP: With PHP you can do a
- * file_get_contents("http://drupal.org/projects") as if it were a file,
- * because the scheme "http" is supported natively in PHP. So Drupal adds
- * the public:// and private:// schemes, and contrib modules can add any
- * scheme they want to. This example adds the session:// scheme, which allows
- * reading and writing the $_SESSION['file_example'] key as if it were a file.
- *
- * Note that because this implementation uses simple PHP arrays ($_SESSION)
- * it is limited to string values, so binary files will not work correctly.
- * Only text files can be used.

-/**
- * @file
- * An example of how to use the new #states Form API element, allowing
- * dynamic form behavior with very simple setup.
- */
-
-/**
- * This form shows off the #states system by dynamically showing parts of the
- * form based on the state of other parts.
- *
- * @ingroup form_example
- *
- * The basic idea is that you add a #states property to the element which is
- * to be changed based on some action elsewhere on the form. The #states
- * property lists a change which is to be made, and under what conditions
- * that change should be made.
- *
- * For example, in the 'tests_taken' form element below we have:
- * @code
- * '#states' => array(
- *   'visible' => array(
- *     ':input[name="student_type"]' => array('value' => t('High School')),
- *   ),
- * ),
- * @endcode
- * Meaning that the element is to be made visible when the condition is met.
- * The condition is a combination of a jQuery selector (which selects the
- * element we want to test) and a condition for that element. In this case,
- * the condition is whether the value of the 'student_type' element is
- * 'High School'. If it is, this element will be visible.
- *
- * So the syntax is:
- * @code
- * '#states' => array(
- *   'action_to_take_on_this_form_element' => array(
- *     'jquery_selector_for_another_element' => array('condition_type' => value),
- *   ),
- * ),
- * @endcode
- *
- * If you need an action to take place only when two different conditions are
- * true, then you add both of those conditions to the action. See the
- * 'country_writein' element below for an example.
- *
- * Note that the easiest way to select a textfield, checkbox, or select is
- * with the @link http://api.jquery.com/input-selector/ ':input' jquery shortcut @endlink,
- * which selects any any of those.
- *
- * There are examples below of changing or hiding an element when a checkbox
- * is checked, when a textarea is filled, when a select has a given value.
- *
- * See drupal_process_states() for full documentation.
- *
- * See also @link http://api.drupal.org/api/drupal/developer--topics--forms_api_reference.html/7#states Form API Reference @endlink

- *
- * This example is an extensible skeleton that can include (even
- * programatically) more steps. The demonstration form includes three steps,
- * each step having its own validation functions.
- *
- * How to extend this example:
- * - Steps are defined in the _form_example_steps() function. Include or alter
- *   the steps as you require.
- * - For each step, implement the corresponding 'form' function (see
- *   'form_example_wizard_personal_info' for the first step in this example.)
- *   Each step is a regular form, and the wizard collects all the values of the
- *   included forms.
- * - Optionally, you may include custom validation functions using the regular
- *   validation hook (formname_validate). The wizard uses these validation
- *   functions for each step.
- * - The most important customization sttep is to change the submit handler and
- *   do whatever you want with the collected information. In this case, the
- *   example just shows the collected values in the various steps.

- * This module demonstrates the use of Drupal 7's new image styles and effects
- * including the following topics.
- *  - Define default image styles in code. Useful for modules that want to ship
- *    with predefined image styles and for site developers who want their image
- *    style configurations to be in version control.
- *    hook_image_default_styles().
- *  - Define new image effects. Demonstrates how a module can add additional
- *    effects to the options available when creating image styles.
- *    hook_image_effect_info().
- *  - Alter existing image styles. Demonstrates the use of
- *    hook_image_styles_alter() to modify existing image effects, especially
- *    those defined by other modules in hook_image_default_styles() without
- *    having to override the styles.
- *  - Demonstrates the use of hook_image_style_save() and
- *    hook_image_style_delete() to update module specific variables when an
- *    image style is either re-named or deleted.
- *  - Generate a form with a field of type #managed_file that allows the user
- *    to upload an image and choose a style to use when displaying that image.
- *  - Demonstrates the use of theme_image_style() to display images using an
- *    image style.

-/**
- * @file
- * This is an example illustrating how to restrict access to nodes based on
- * the node access system. It implements an additional "private" marker for
- * each node. The idea is that only the user (or specially permissioned users)
- * can access a "private" node.
- *
- * The node access system has three layers.
- * - Overall override permissions. User 1 and any user with 'bypass node access'
- *   permission are automatically granted access.
- * - hook_node_access() gives each module the opportunity to approve or deny
- *   access. Any module that returns NODE_ACCESS_DENY from hook_node_access()
- *   will result in denial of access. If no module denies access and one or
- *   more modules allow access, then access is granted.
- * - If no resolution has yet been reached, then the node_access table is used
- *   along with hook_node_grants().
- *
- * In order to demonstrate hook_node_access() (see
- * node_example_module_node_access()) to deny delete access to users with an
- * even-numbered uid.
- *
- * In addition, the traditional node rights system is employed to specify
- * which users are allowed to view, edit, or delete "private" content.
- *
- * This puts a single marker on a node: 'private'. The marker is implemented
- * by a custom table which has one row per node simply indicating that the node
- * is private. If the "private" marker is set, other users are denied access.
- *
- * Additional standard permissions are defined which allow users with
- * 'access any private content' or 'edit any private content' to override
- * the node access restrictions.
- *
- * Additionally, the node author can always view, edit, and delete the node.
- * A separate access realm grants privileges to each node's author.
- *
- * There are two basic building blocks in the node access system.
- * - hook_node_access_records() provides a list of "grants" for each node.
- * - hook_node_grants() provides determines which of those grants
- *   is available for a given user account.
- *
- * Note that current best practice is probably to interoperate with the
- * @link http://drupal.org/project/acl ACL module @endlink rather than directly
- * implementing node access.
- *
- * It's also critical to understand when working with node access rights that
- * normally one would only use one module granting node access. That's the
- * reason that ACL module has come to the fore, as it becomes the central
- * clearing house for granting access. The problem with node acces is that
- * it is a granting system, not a restricting system. As a result, the first
- * module that grants access wins, even though some other node access module
- * might have wanted not to grant access. So there's enormous (potential)
- * ambiguity if one tries to use more than one node access module.
- *
- * The only page provided by this module gives a rundown of how many nodes

-/**
- * @file
- * This is an example outlining how a module can be used to define a new
- * node type.  In Drupal 7 we move most of what was once needed in this file
- * to the node_example.install file so that it can be managed efficiently.
- *
- * Our example node type will allow users to specify multiple "colors",
- * a "quantity" and an "image" for their nodes; some kind of rudimentary
- * inventory-tracking system, perhaps?
- *
- * In previous versions of Drupal, "teaser" and "page" were node view modes.  In
- * Drupal 7 we can define custom view modes to let the node know how it should
- * return it's data.  This module declares a custom view mode called
- * "example_node_list".
- *
- * We no longer need an extra database table to store this content type's
- * information.
- *
- * Most node types that provide fields do not require any custom code for
- * the fields, as the fields system provides storage and access.

-/**
- * @file
- * Examples demonstrating the Drupal Queue API.
- *
- * The Queue API provides a traditional FIFO (first-in-first-out) queue,
- * but also provides the concepts of:
- * - "Creating" a queued item, which means inserting it into a queue.
- * - "Claiming" a queued item, which essentially means requesting the next item
- *   from the queue and holding a lock on that item for a specified period of
- *   time.
- * - "Releasing" an item, which means giving up a claim but leaving the item in
- *   the queue.
- * - "Deleting" an item, which means finally removing it from the queue.
- *
- * This example demonstrates only basic queue functionality, and will use the
- * default queue implementation, which is SystemQueue, managed using
- * persistent database storage.
- *
- * Further resources include the limited @link queue @endlink documentation and
- * @link http://www.ent.iastate.edu/it/Batch_and_Queue.pdf Batch vs Queue Presentation slides by John VanDyk @endlink
- * and @link http://sf2010.drupal.org/conference/sessions/batch-vs-queue-api-smackdown session video. @endlink

-/**
- * @file
- * Trigger definition example module.
- *
- * Triggers and actions are a pair of special-purpose functions allowing some
- * Drupal programming without using PHP. Using the
- * appropriate action in a specific event, a site administrator can
- * add new functionality. Examples are:
- *  - Send an email after a node is published or edited.
- *  - Display a message after a user has logged in.
- *  - Display a message and send an email after a node has been deleted.
- *
- * A Trigger is a special function able to enqueue actions. The trigger module
- * provides the interface allowing us to associate certain actions with certain
- * triggers.
- *
- * Actions are functions intended to be run by triggers.
- *
- * A trigger should build the appropriate context for the action to be fired.
- * Actions are very often
- * grouped by functionality: examples are 'user', 'node', 'taxonomy'. When some
- * actions are grouped it is because they expect the same arguments. This way,
- * you can enqueue as many actions understanding the 'user' object as you want.
- *
- * Not all actions can be used in all triggers because they require different
- * contexts. But some actions
- * are generic enough to not require special objects in their
- * contexts, and so can be used on every available trigger. This 'group' type
- * is used by actions to be available for this trigger.
- *
- * What are good candidates to be triggers? Any function can be a trigger, as
- * long as it has the code to call the enqueued actions, but to make Drupal
- * more extensible, you will find hooks (from Drupal and contributed modules)
- * very good candidates. A trigger should build the arguments, ask for enqueued
- * actions and run them. You may define a function being a trigger, and run it
- * through a button in the front page, or you may prepare a trigger for a hook,
- * and everytime that hook is fired, your trigger will be.
- *
- * What are good candidates to be actions? any function is a possible action,
- * the only problem is finding a trigger able to run it.
- *
- * This module describes how to create triggers and actions for Drupal. In this
- * example we are providing two triggers:
- *
- * - A custom trigger, in its simplest form. We provide a page with a button.
- *   This button does nothing at all, but when you click (and submit the empty
- *   form), any actions you have configured will be executed.
- *
- * - A trigger which extends the capabilities of User triggers.
- *   This creates a new event which fires the first time a user ever logs in.
- *   In the module we will create it, and then provide a trigger for
- *   the administrator to be able to enqueue actions. They will be executed
- *   only the first time the user logs in the system.
- *
- * See:
- *
- * @link http://drupal.org/node/375833 Creating Triggers @endlink
- *
- * @link http://drupal.org/node/172152 Writing Actions @endlink

- * Triggers are the events that make fire any number of assigned actions. In
- * this example, we are registering our three new triggers, providing the group
- * (system, user..), the callback 'hook' (only informative, does not require a
- * real hook) function and the label to be shown in the triggers interface.
- *
- * Example: In the group (a tab) 'system', for the 'mail' functionality, show:
