-# Sort the contents of this file into a Spork.prefork and a Spork.each_run
-# block.
-#
-# The Spork.prefork block is run only once when the spork server is started.
-# You typically want to place most of your (slow) initializer code in here, in
-# particular, require'ing any 3rd-party gems that you don't normally modify
-# during development.
-#
-# The Spork.each_run block is run each time you run your specs.  In case you
-# need to load files that tend to change during development, require them here.
-# With Rails, your application modules are loaded automatically, so sometimes
-# this block can remain empty.
-#
-# Note: You can modify files loaded *from* the Spork.each_run block without
-# restarting the spork server.  However, this file itself will not be reloaded,
-# so if you change any of the code inside the each_run block, you still need to
-# restart the server.  In general, if you have non-trivial code in this file,
-# it's advisable to move it into a separate file so you can easily edit it
-# without restarting spork.  (For example, with RSpec, you could move
-# non-trivial code into a file spec/support/my_helper.rb, making sure that the
-# spec/support/* files are require'd from inside the each_run block.)
-#
-# Any code that is left outside the two blocks will be run during preforking
-# *and* during each_run -- that's probably not what you want.
-#
-# These instructions should self-destruct in 10 seconds.  If they don't, feel
-# free to delete them.
