Run "m help" for help with the build system itself.

Invoke ". build/envsetup.sh" from your shell to add the following functions to your environment:
- lunch:     lunch <product_name>-<build_variant>
             Selects <product_name> as the product to build, and <build_variant> as the variant to
             build, and stores those selections in the environment to be read by subsequent
             invocations of 'm' etc.
- tapas:     tapas [<App1> <App2> ...] [arm|x86|mips|arm64|x86_64|mips64] [eng|userdebug|user]
- croot:     Changes directory to the top of the tree.
- m:         Makes from the top of the tree.
- mm:        Builds all of the modules in the current directory, but not their dependencies.
- mmm:       Builds all of the modules in the supplied directories, but not their dependencies.
             To limit the modules being built use the syntax: mmm dir/:target1,target2.
- mma:       Builds all of the modules in the current directory, and their dependencies.
- mmma:      Builds all of the modules in the supplied directories, and their dependencies.
- provision: Flash device with all required partitions. Options will be passed on to fastboot.
- cgrep:     Greps on all local C/C++ files.
- ggrep:     Greps on all local Gradle files.
- jgrep:     Greps on all local Java files.
- resgrep:   Greps on all local res/*.xml files.
- mangrep:   Greps on all local AndroidManifest.xml files.
- mgrep:     Greps on all local Makefiles files.
- sepgrep:   Greps on all local sepolicy files.
- sgrep:     Greps on all local source files.
- godir:     Go to the directory containing a file.
