 # Been trying to settling line 17 for Titanium implementation.
 # So far I found that it is very easy to import the whole project
 # into Titanium then later on with certain tweaks should be able 
 # to export for mobile web application from Titanium IDE.
 # According to Dan's comment might be because of Ruby language
 # version are not compatible, I suggest import this project to 
 # Titanium framework and see for yourself to whom interesting 
 # in multi-platforms exportation. Thanks, Christopherys.
