There doesn't seem to be documentation on how to build a production mode app for ST2 using Sencha Cmd utility on their web site anywhere. Can anyone point me in the right direction?
There is no difference in command to build your app between SDK Tools and Sencha Cmd:
To build your app for testing:
sencha app build testing
To build your app for production deployment:
sencha app build production
To package your application for distribution on App Stores:
sencha app build native
