  *   A keyed array of tasks the profile will perform during the final stage of
  *   the installation. Each key represents the name of a function (usually a
  *   function defined by this profile, although that is not strictly required)
  *   that is called when that task is run. The values are associative arrays
  *   containing the following key-value pairs (all of which are optional):
- *     - 'display_name'
- *       The human-readable name of the task. This will be displayed to the
- *       user while the installer is running, along with a list of other tasks
- *       that are being run. Leave this unset to prevent the task from
- *       appearing in the list.
- *     - 'display'
- *       This is a boolean which can be used to provide finer-grained control
- *       over whether or not the task will display. This is mostly useful for
- *       tasks that are intended to display only under certain conditions; for
- *       these tasks, you can set 'display_name' to the name that you want to
- *       display, but then use this boolean to hide the task only when certain
- *       conditions apply.
- *     - 'type'
- *       A string representing the type of task. This parameter has three
- *       possible values:
- *       - 'normal': This indicates that the task will be treated as a regular
- *       callback function, which does its processing and optionally returns
- *       HTML output. This is the default behavior which is used when 'type' is
- *       not set.
- *       - 'batch': This indicates that the task function will return a batch
- *       API definition suitable for batch_set(). The installer will then take
- *       care of automatically running the task via batch processing.
- *       - 'form': This indicates that the task function will return a standard

+ *     - batch: This indicates that the task function will return a batch API
+ *       definition suitable for batch_set(). The installer will then take care
+ *       of automatically running the task via batch processing.
+ *     - form: This indicates that the task function will return a standard
  *       form API definition (and separately define validation and submit
  *       handlers, as appropriate). The installer will then take care of
  *       automatically directing the user through the form submission process.
- *     - 'run'
- *       A constant representing the manner in which the task will be run. This
- *       parameter has three possible values:
- *       - INSTALL_TASK_RUN_IF_NOT_COMPLETED: This indicates that the task will
- *       run once during the installation of the profile. This is the default
- *       behavior which is used when 'run' is not set.

+ *       task will run once during the installation of the profile.
+ *     - INSTALL_TASK_SKIP: This indicates that the task will not run during
  *       the current installation page request. It can be used to skip running
  *       an installation task when certain conditions are met, even though the
  *       task may still show on the list of installation tasks presented to the
  *       user.

- *       Normally this does not need to be set, but it can be used to force the
