Purpose:
========
This tool allows you to have a message read in from standard input, and
then sent to all translators via email. If you use %(lang)s in the message
it will be replaced with the appropriate language code for the translator.

Detailed Instructions:
======================
General syntax: moin [options] maint mailtranslators [mailtranslators-options]

[options] usually should be:
    --config-dir=/path/to/my/cfg/ --wiki-url=http://wiki.example.org/

[mailtranslators-options] see below:
    0. To send an email to all translaters, from john@smith.com, and with a subject
       of 'Please update your translations!' and a body of 'Please update your language,
       %(lang)s'
       moin ... maint mailtranslators --from-address john@smith.com --subject 'Please update your translations!'
       Please update your language, %(lang)s
