 | - 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. |

 | - sepgrep:   Greps on all local sepolicy files. | 
 | - sgrep:     Greps on all local source files. | 
 | - godir:     Go to the directory containing a file. | 
 |  | 
 | Environment options: | 
 | - SANITIZE_HOST: Set to 'true' to use ASAN for all host modules. Note that |
