cat <<EOF
Invoke ". build/envsetup.sh" from your shell to add the following functions to your environment:
- lunch:     lunch <product_name>-<build_variant>
- tapas:     tapas [<App1> <App2> ...] [arm|x86|mips|armv5|arm64|x86_64|mips64] [eng|userdebug|user]
- croot:     Changes directory to the top of the tree.
- cout:      Changes directory to out.
- 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.
- mmap:      Builds all of the modules in the current directory, and its dependencies, then pushes the package to the device.
- mmp:       Builds all of the modules in the current directory and pushes them to the device.
- mmmp:      Builds all of the modules in the supplied directories and pushes them to the device.
- mms:       Short circuit builder. Quickly re-build the kernel, rootfs, boot and system images
             without deep dependencies. Requires the full build to have run before.
- 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.
- cmremote:  Add git remote for CM Gerrit Review
- cmgerrit:  A Git wrapper that fetches/pushes patch from/to CM Gerrit Review
- aospremote: Add git remote for matching AOSP repository
- cafremote: Add git remote for matching CodeAurora repository.
- cmrebase:  Rebase a Gerrit change and push it again
- mka:       Builds using SCHED_BATCH on all processors
- mkap:      Builds the module(s) using mka and pushes them to the device.
- cmka:      Cleans and builds using mka.
- repolastsync: Prints date and time of last repo sync.
- reposync:  Parallel repo sync using ionice and SCHED_BATCH
- repopick:  Utility to fetch changes from Gerrit.
- installboot: Installs a boot.img to the connected device.
- installrecovery: Installs a recovery.img to the connected device.
- repodiff:  Diff 2 different branches or tags within the same repo

Environment 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
                 build is leak-check clean.

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.
