autobuild.rb

gistfile1.txt

# This file is to rebuild the dist env automatically so that you don't have to 
# rerun ant deploy all the time
#
# To run, install watchr gem  
#
#    gem install watchr
#
# Then simply run
#
#    watchr autobuild.rb
#
# Now everytime you make change to nikio or the atmosphere.js files, the
# nikio.js file will be built correctly.
