# This Snippet may do to be able to refer all definitions of libraries
# from RubyMotion REPL, when You paste this Snippet on bottommost of
# your RubyMotion Rakefile.  But it is very slow...

# Usage:
#   rake preload=true   # generate preload source file before build simulator
#
#   rake preload:clean  # delete preload source file
