Invoke ". build/envsetup.sh" from your shell to add the following functions to your environment:
- build:   build {sdl_app_name} [-s] [-i] [-r] [release]
- croot:   Changes directory to the top of the tree.
- cgrep:   Greps on all local C/C++ files.
- jgrep:   Greps on all local Java files.
- resgrep: Greps on all local res/*.xml files.
- godir:   Go to the directory containing a file.
