##
# Adds sending email through an ActiveRecord table as a delivery method for
# ActionMailer.

# == Converting to ActionMailer::ARMailer
#
# Go to your Rails project:
# 
#   $ cd your_rails_project
# 
# Create a new migration:
# 
#   $ ar_sendmail --create-migration
# 
# You'll need to redirect this into a file.  If you want a different name
# provide the --table-name option.
# 
# Create a new model:
# 
#   $ ar_sendmail --create-model
# 
# You'll need to redirect this into a file.  If you want a different name
# provide the --table-name option.
# 
# Change your email classes to inherit from ActionMailer::ARMailer instead of
# ActionMailer::Base:
