# travis-core holds the central parts of the model layer used in both travis-ci
# (i.e. the web application) as well as travis-hub (a non-rails ui-less JRuby
# application that receives, processes and distributes messages from/to the
# workers and issues various events like email, pusher, irc notifications and
# so on).
#
# travis/model   - contains ActiveRecord models that and model the main
#                  parts of the domain logic (e.g. repository, build, job
#                  etc.) and issue events on state changes (e.g.
#                  build:created, job:test:finished etc.)
# travis/event   - contains event handlers that register for certain
#                  events and send out such things as email, pusher, irc
#                  notifications, archive builds or queue jobs for the
#                  workers.
# travis/mailer  - contains ActionMailers for sending out email
#                  notifications
#
# travis-core also contains some helper classes and modules like Travis::Database
# (needed in travis-hub in order to connect to the database) and Travis::Renderer
# (our inferior layer on top of Rabl).
