= Exception Notifier Plugin for Rails

The Exception Notifier plugin provides a mailer object and a default set of
templates for sending email notifications when errors occur in a Rails
application. The plugin is configurable, allowing programmers to specify:

* the sender address of the email
* the recipient addresses
* the text used to prefix the subject line

The email includes information about the current request, session, and
environment, and also gives a backtrace of the exception.
