The sencha app build command works by reading your index.html and scanning forrequired classes. If your application does not properly declare the classes it requires,the build usually completes but will not contain all the classes needed by yourapplication.

DOWNLOAD

We also need to download and install Sencha Cmd from -cmd/download. Sencha Cmd is responsible for creating the application and making, building, and compiling Sass and Compass to generate the application's CSS. After the installation of Sencha Cmd, the sencha command will be available from the terminal application as well.

The sencha generate app command takes two parameters: the name of the app (inthis case NewApp) and the location (in this case, the NewAppFolder, which isa subfolder of the current location). The -sdk switch specifies the location(anywhere in the disk) of the Sencha Touch distribution (namely, the foldercreated when the ZIP file is unzipped.)

Sencha Cmd provides many other services, which we will see in detail inChapter 10. For the moment, suffice to say that the sencha commandbuilds an application that conforms to the MVC standard enforced by SenchaTouch.
