# redmine reader isn't actually specific to redmine, but it is specific to
# awesome. redmine reader's job is to take an ATOM feed generated by redmine
# and clear out all the crap they usually display with (poorly!), then package
# that up nicely and shoot it out to an email address.
#
# there's a config file you can include. but it has passwords in it, so you'll
# have to make it yourself
