WHAT IT DOES:
-------------
This module allows users, when creating or editing a node, to select
which roles of users on a site will have 'view' permissions for the
node and which users on a site will have 'edit' permissions for the
node.  Roles given edit permissions are automatically given view
permissions even if the user tries to give 'edit' permissions to
a particular role, but not view permissions.

TO INSTALL:
-----------
Drop the node_privacy_byrole.module into the 'modules' directory
of your drupal installation.

TO ENABLE:
----------
Enable the module as you would any other module.  However, you will
also need to go to the node_privacy_byrole's settings page and explicity
enable it there.

TO DISABLE:
-----------
Before disabling the module by disabling it the way you would for any
other drupal module, go to the node_privacy_byrole's settings page and
explicitly disable it there.

OTHER NOTES:
------------
If the module is enable, by-role permissions are set by users for
their nodes, and then the module is disabled, the default permissions
scheme will be in effect again, in which all users have view permissions 
for all nodes.  However, if the module is re-enabled, the node-by-node
permissions that were in place during the previous period in which the
module was enabled will take effect again.
