In an attempt to improve my workflow in RubyMotion, I have been experimenting with ways to abstract the few details that must be changed from one application to the next.
This Rakefile exists in a root directory.
Each new project has a copy of the app_properties.rb (with all the appropriate details) and a symlink to the Rakefile.
In this way, I can simplify (and hopefully expedite) the process.
