 If you add @marrow.mailer@ to the @install_requires@ argument of the call to @setup()@ in your application's @setup.py@ file, @marrow.mailer@ will be automatically installed and made available when your own application is installed.  We recommend using "less than" version numbers to ensure there are no unintentional side-effects when updating.  Use @"marrow.mailer<4.1"@ to get all bugfixes for the current release, and @"marrow.mailer<5.0"@ to get bugfixes and feature updates, but ensure that large breaking changes are not installed.
