- 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.
- cgrep:   Greps on all local C/C++ files.
- ggrep:   Greps on all local Gradle files.

- resgrep: Greps on all local res/*.xml files.
- mangrep: Greps on all local AndroidManifest.xml files.
- sepgrep: Greps on all local sepolicy files.
- sgrep:   Greps on all local source files.
- godir:   Go to the directory containing a file.
- cmremote: Add git remote for CM Gerrit Review
- cmgerrit: A Git wrapper that fetches/pushes patch from/to CM Gerrit Review
- cmrebase: Rebase a Gerrit change and push it again
- mka:      Builds using SCHED_BATCH on all processors
- reposync: Parallel repo sync using ionice and SCHED_BATCH

Environemnt options:
- SANITIZE_HOST: Set to 'true' to use ASAN for all host modules. Note that
                 ASAN_OPTIONS=detect_leaks=0 will be set by default until the

Usage:
    $FUNCNAME COMMAND [OPTIONS] [CHANGE-ID[/PATCH-SET]][{@|^|~|:}ARG] [-- ARGS]

Commands:
    fetch   Just fetch the change as FETCH_HEAD
    help    Show this help, or for a specific command
    pull    Pull a change into current branch
    push    Push HEAD or a local branch to Gerrit for a specific branch

Any other Git commands that support refname would work as:
    git fetch URL CHANGE && git COMMAND OPTIONS FETCH_HEAD{@|^|~|:}ARG -- ARGS

See '$FUNCNAME help COMMAND' for more information on a specific command.

Example:
    $FUNCNAME checkout -b topic 1234/5
works as:
    git fetch http://DOMAIN/p/PROJECT refs/changes/34/1234/5 \\
      && git checkout -b topic FETCH_HEAD
will checkout a new branch 'topic' base on patch-set 5 of change 1234.
Patch-set 1 will be fetched if omitted.
