RandomSupport
=============
**Usage**

.. code-block:: chapel

or

.. code-block:: chapel

   import Random.RandomSupport;


Seed generation for pseudorandom number generation.

.. warning:

  The ``RandomSupport`` sub-module and its contents are deprecated

.. note::

  For many of the functions in :mod:`Random`, if no seed is provided by the
  user, one is chosen based on the current time in microseconds, allowing
  for some degree of variability in seed selection.  The intent of
  :record:`SeedGenerator` is to provide a menu of other options for
  initializing the random stream seed, but few options are implemented
  at present. In particular, it would be useful to allow multiple tasks to
  create different seeds at the same time, or to allow different
  functions running at the same time to produce different seeds.



.. type:: type SeedGenerator = _SeedGenerator

   .. warning::

      'SeedGenerator' is deprecated

   
   Provides methods to help generate seeds when the user doesn't want
   to create one.  It currently supports two type methods. Both start
   with the current time.
