How to package (minify) an extjs 4 application
===

I am looking for de facto instructions for packaging and minfying an Ext JS 4 app.

Everything seems to point to the Sencha SDK, but everything around this is targeted at Sencha Touch, and anyway, when I follow the instructions I receive:

"The current working directory (C:\...)  is not a recognized Sencha SDK or application folder"

Which throws me, since the structure I am using was generated by Sencha Achitect.

I'd expect loads of posts/guides/blogs/articles on this what you'd think would be a common requirement givent the shed load of .js files one creates whilst developing.
