This is an ant file with targets for initializing / maintaining this example
repo.  To initialize a repo after an initial git clone operation, run the
"install-frameworks" target.
            
Targets:
            
    get-frameworks          :   downloads ext and touch from cdn.sencha.com
    install-frameworks      :   downloads and installs ext and touch into the workspaces
