.kick

# Uses the kicker gem, a file-change watcher, using OS X FSEvents:
#
#   http://github.com/alloy/kicker
#   gem install kicker -s http://gemcutter.org
#
# to send a reload command via Drb to a running spork_server:
#
#   http://github.com/timcharper/spork/
#   gem install spork
#
# which should cause spork to reload rails.
#
# * Note the changes to spork to support reload are
# * currently only in the reload branch in my fork of
# * spork: http://github.com/stepheneb/spork
#
# Start the two server processes in console windows:
#
#   spork rspec
#   kicker
#
# When you make a change to a file in app/, lib/, or config/ this .kick
# script will send a reload message to spork to reload rails.
