update.module

Handles updates of Drupal core and contributed projects.

The module checks for available updates of Drupal core and any installed contributed modules and themes. It warns site administrators if newer releases are available via the system status report (admin/reports/status), the module and theme pages, and optionally via e-mail. It also provides the ability to install contributed modules and themes via an user interface.
