 -v=false
   Print verbose output.

The global flags are:
 -metadata=<just specify -metadata to activate>
   Displays metadata for the program and exits.
 -time=false
   Dump timing information to stderr before exiting the program.

Jiri cl - Manage project changelists

Manage project changelists.

Usage:
   jiri cl [flags] <command>

The jiri cl commands are:
   cleanup     Clean up changelists that have been merged
   mail        Mail a changelist for review
   new         Create a new local branch for a changelist
   sync        Bring a changelist up to date

The jiri cl flags are:
 -color=true
   Use color to format output.
 -v=false
   Print verbose output.

Jiri cl cleanup - Clean up changelists that have been merged

Command "cleanup" checks that the given branches have been merged into the
corresponding remote branch. If a branch differs from the corresponding remote
branch, the command reports the difference and stops. Otherwise, it deletes the
given branches.

Usage:
   jiri cl cleanup [flags] <branches>

<branches> is a list of branches to cleanup.

The jiri cl cleanup flags are:
 -f=false
   Ignore unmerged changes.
 -remote-branch=master
   Name of the remote branch the CL pertains to, without the leading "origin/".

 -color=true
   Use color to format output.
 -v=false
   Print verbose output.

Jiri cl mail - Mail a changelist for review

Command "mail" squashes all commits of a local branch into a single "changelist"
and mails this changelist to Gerrit as a single commit. First time the command
is invoked, it generates a Change-Id for the changelist, which is appended to
the commit message. Consecutive invocations of the command use the same
Change-Id by default, informing Gerrit that the incomming commit is an update of
an existing changelist.

Usage:
   jiri cl mail [flags]

The jiri cl mail flags are:
 -autosubmit=false
   Automatically submit the changelist when feasible.
 -cc=
   Comma-seperated list of emails or LDAPs to cc.
 -check-uncommitted=true
   Check that no uncommitted changes exist.
 -d=false
   Send a draft changelist.
 -edit=true
   Open an editor to edit the CL description.
 -host=
   Gerrit host to use.  Defaults to gerrit host specified in manifest.
 -m=
   CL description.

   The type of presubmit tests to run. Valid values: none,all.
 -r=
   Comma-seperated list of emails or LDAPs to request review.
 -remote-branch=master
   Name of the remote branch the CL pertains to, without the leading "origin/".
 -set-topic=true
   Set Gerrit CL topic.
 -topic=
   CL topic, defaults to <username>-<branchname>.
 -verify=true
   Run pre-push git hooks.

 -color=true
   Use color to format output.
 -v=false
   Print verbose output.

Jiri cl new - Create a new local branch for a changelist

Command "new" creates a new local branch for a changelist. In particular, it
forks a new branch with the given name from the current branch and records the
relationship between the current branch and the new branch in the .jiri metadata
directory. The information recorded in the .jiri metadata directory tracks
dependencies between CLs and is used by the "jiri cl sync" and "jiri cl mail"
commands.

Usage:
   jiri cl new [flags] <name>

<name> is the changelist name.

The jiri cl new flags are:
 -color=true
   Use color to format output.
 -v=false
   Print verbose output.

Jiri cl sync - Bring a changelist up to date

Command "sync" brings the CL identified by the current branch up to date with
the branch tracking the remote branch this CL pertains to. To do that, the
command uses the information recorded in the .jiri metadata directory to
identify the sequence of dependent CLs leading to the current branch. The
command then iterates over this sequence bringing each of the CLs up to date
with its ancestor. The end result of this process is that all CLs in the
sequence are up to date with the branch that tracks the remote branch this CL
pertains to.

NOTE: It is possible that the command cannot automatically merge changes in an
ancestor into its dependent. When that occurs, the command is aborted and prints
instructions that need to be followed before the command can be retried.

Usage:
   jiri cl sync [flags]

The jiri cl sync flags are:
 -remote-branch=master
   Name of the remote branch the CL pertains to, without the leading "origin/".

 -color=true
   Use color to format output.
 -v=false
   Print verbose output.

   jiri contributors [flags] <projects>

<projects> is a list of projects to consider.

The jiri contributors flags are:
 -aliases=
   Path to the aliases file.
 -n=false
   Show number of contributions.

 -color=true
   Use color to format output.
 -v=false
   Print verbose output.

Jiri import

Command "import" adds imports to the $JIRI_ROOT/.jiri_manifest file, which
specifies manifest information for the jiri tool.  The file is created if it
doesn't already exist, otherwise additional imports are added to the existing
file.

An <import> element is added to the manifest representing a remote manifest
import.  The manifest file path is relative to the root directory of the remote
import repository.

Example:
  $ jiri import myfile https://foo.com/bar.git

Run "jiri help manifest" for details on manifests.

   projects with the same remote.  Typically empty.
 -out=
   The output file.  Uses $JIRI_ROOT/.jiri_manifest if unspecified.  Uses stdout
   if set to "-".

Internally, snapshots are organized as follows:

 <snapshot-dir>/
   labels/
     <label1>/
       <label1-snapshot1>
       <label1-snapshot2>
       ...

     <label3>/
     ...
   <label1> # a symlink to the latest <label1-snapshot*>
   <label2> # a symlink to the latest <label2-snapshot*>
   ...

NOTE: Unlike the jiri tool commands, the above internal organization is not an
API. It is an implementation and can change without notice.

Usage:
   jiri snapshot create [flags] <label>

<label> is the snapshot label.

The jiri snapshot create flags are:
 -push-remote=false
   Commit and push snapshot upstream.

   Print verbose output.

Jiri update - Update all jiri tools and projects

Updates all projects, builds the latest version of all tools, and installs the
resulting binaries into $JIRI_ROOT/.jiri_root/bin. The sequence in which the
individual updates happen guarantees that we end up with a consistent set of
tools and source code. The set of projects and tools to update is described in
the manifest.

Run "jiri help manifest" for details on manifests.

Usage:
   jiri update [flags]

The jiri update flags are:
 -attempts=1
   Number of attempts before failing.

   Name of the project manifest.

 -color=true
   Use color to format output.
 -v=false
   Print verbose output.

Jiri upgrade - Upgrade jiri to new-style manifests

Upgrades jiri to use new-style manifests.

The old (deprecated) behavior only allowed a single manifest repository, located
in $JIRI_ROOT/.manifest.  The initial manifest file is located as follows:
  1) Use -manifest flag, if non-empty.  If it's empty...
  2) Use $JIRI_ROOT/.local_manifest file.  If it doesn't exist...
  3) Use $JIRI_ROOT/.manifest/v2/default.

The new behavior allows multiple manifest repositories, by allowing imports to
specify project attributes describing the remote repository.  The -manifest flag
is no longer allowed to be set; the initial manifest file is always located in
$JIRI_ROOT/.jiri_manifest.  The .local_manifest file is ignored.

During the transition phase, both old and new behaviors are supported.  The jiri
tool uses the existence of the $JIRI_ROOT/.jiri_manifest file as the signal; if
it exists we run the new behavior, otherwise we run the old behavior.

The new behavior includes a "jiri import" command, which writes or updates the
.jiri_manifest file.  The new bootstrap procedure runs "jiri import", and it is
intended as a regular command to add imports to your jiri environment.

This upgrade command eases the transition by writing an initial .jiri_manifest
file for you.  If you have an existing .local_manifest file, its contents will
be incorporated into the new .jiri_manifest file, and it will be renamed to
.local_manifest.BACKUP.  The -revert flag deletes the .jiri_manifest file, and
restores the .local_manifest file.

Usage:
   jiri upgrade [flags] <kind>

<kind> specifies the kind of upgrade, one of "v23" or "fuchsia".

The jiri upgrade flags are:
 -revert=false
   Revert the upgrade by deleting the $JIRI_ROOT/.jiri_manifest file.

 -color=true
   Use color to format output.
 -v=false
   Print verbose output.

Jiri which - Show path to the jiri tool

Which behaves similarly to the unix commandline tool.  It is useful in
determining whether the jiri binary is being run directly, or run via the jiri
shim script.

If the binary is being run directly, the output looks like this:

  # binary
  /path/to/binary/jiri

If the script is being run, the output looks like this:

  # script
  /path/to/script/jiri

Usage:
   jiri which [flags]

The jiri which flags are:
 -color=true
   Use color to format output.
 -v=false
   Print verbose output.

Jiri help - Display help for commands or topics

Help with no args displays the usage of the parent command.

Help with args displays the usage of the specified sub-command or help topic.

"help ..." recursively displays help for all commands and topics.

Usage:
   jiri help [flags] [command/topic ...]

[command/topic ...] optionally identifies a specific sub-command or help topic.

The jiri help flags are:
 -style=compact
   The formatting style for help output:
      compact   - Good for compact cmdline output.
      full      - Good for cmdline output, shows all global flags.
      godoc     - Good for godoc processing.
      shortonly - Only output short description.
   Override the default by setting the CMDLINE_STYLE environment variable.
 -width=<terminal width>
   Format output to this target width in runes, or unlimited if width < 0.
   Defaults to the terminal width if available.  Override the default by setting
   the CMDLINE_WIDTH environment variable.

Jiri filesystem - Description of jiri file system layout

All data managed by the jiri tool is located in the file system under a root
directory, colloquially called the jiri root directory.  The file system layout
looks like this:

 [root]                              # root directory (name picked by user)
 [root]/.jiri_root                   # root metadata directory
 [root]/.jiri_root/bin               # contains tool binaries (jiri, etc.)
 [root]/.jiri_root/update_history    # contains history of update snapshots
 [root]/.manifest                    # contains jiri manifests
 [root]/[project1]                   # project directory (name picked by user)
 [root]/[project1]/.jiri             # project metadata directory
 [root]/[project1]/.jiri/metadata.v2 # project metadata file
 [root]/[project1]/.jiri/<<cls>>     # project per-cl metadata directories
 [root]/[project1]/<<files>>         # project files
 [root]/[project2]...

The [root] and [projectN] directory names are picked by the user.  The <<cls>>
are named via jiri cl new, and the <<files>> are named as the user adds files
and directories to their project.  All other names above have special meaning to
the jiri tool, and cannot be changed; you must ensure your path names don't
collide with these special names.

There are two ways to run the jiri tool:

1) Shim script (recommended approach).  This is a shell script that looks for
the [root] directory.  If the JIRI_ROOT environment variable is set, that is
assumed to be the [root] directory.  Otherwise the script looks for the
.jiri_root directory, starting in the current working directory and walking up
the directory chain.  The search is terminated successfully when the .jiri_root
directory is found; it fails after it reaches the root of the file system.  Thus
the shim must be invoked from the [root] directory or one of its subdirectories.

Once the [root] is found, the JIRI_ROOT environment variable is set to its
location, and [root]/.jiri_root/bin/jiri is invoked.  That file contains the
actual jiri binary.

The point of the shim script is to make it easy to use the jiri tool with
multiple [root] directories on your file system.  Keep in mind that when "jiri
update" is run, the jiri tool itself is automatically updated along with all
projects.  By using the shim script, you only need to remember to invoke the
jiri tool from within the appropriate [root] directory, and the projects and
tools under that [root] directory will be updated.

The shim script is located at [root]/release/go/src/v.io/jiri/scripts/jiri

2) Direct binary.  This is the jiri binary, containing all of the actual jiri
tool logic.  The binary requires the JIRI_ROOT environment variable to point to
the [root] directory.

Note that if you have multiple [root] directories on your file system, you must
remember to run the jiri binary corresponding to the setting of your JIRI_ROOT
environment variable.  Things may fail if you mix things up, since the jiri
binary is updated with each call to "jiri update", and you may encounter version
mismatches between the jiri binary and the various metadata files or other
logic.  This is the reason the shim script is recommended over running the
binary directly.

The jiri binary is located at [root]/.jiri_root/bin/jiri

Jiri manifest - Description of manifest files

Jiri manifest files describe the set of projects that get synced and tools that
get built when running "jiri update".

The first manifest file that jiri reads is in $JIRI_ROOT/.jiri_manifest.  This
manifest **must** exist for the jiri tool to work.

Usually the manifest in $JIRI_ROOT/.jiri_manifest will import other manifests
from remote repositories via <import> tags, but it can contain its own list of
projects and tools as well.

Manifests have the following XML schema:

<manifest>
  <imports>
    <import remote="https://vanadium.googlesource.com/manifest"
            manifest="public"
            name="manifest"
    />
    <localimport file="/path/to/local/manifest"/>
    ...
  </imports>
  <projects>
    <project name="my-project"
             path="path/where/project/lives"
             protocol="git"
             remote="https://github.com/myorg/foo"
             revision="ed42c05d8688ab23"
             remotebranch="my-branch"
             gerrithost="https://myorg-review.googlesource.com"
             githooks="path/to/githooks-dir"
             runhook="path/to/runhook-script"
    />
    ...
  </projects>
  <tools>
    <tool name="jiri"
          package="v.io/jiri"
          project="release.go.jiri"
    />
    ...
  </tools>
</manifest>

The <import> and <localimport> tags can be used to share common projects and
tools across multiple manifests.

A <localimport> tag should be used when the manifest being imported and the
importing manifest are both in the same repository, or when neither one is in a
repository.  The "file" attribute is the path to the manifest file being
imported.  It can be absolute, or relative to the importing manifest file.

If the manifest being imported and the importing manifest are in different
repositories then an <import> tag must be used, with the following attributes:

* remote (required) - The remote url of the repository containing the manifest
to be imported

* manifest (required) - The path of the manifest file to be imported, relative
to the repository root.

* name (optional) - The name of the project corresponding to the manifest
repository.  If your manifest contains a <project> with the same remote as the
manifest remote, then the "name" attribute of on the <import> tag should match
the "name" attribute on the <project>.  Otherwise, jiri will clone the manifest
repository on every update.

The <project> tags describe the projects to sync, and what state they should
sync to, accoring to the following attributes:

* name (required) - The name of the project.

* path (required) - The location where the project will be located, relative to
the jiri root.

* remote (required) - The remote url of the project repository.

* protocol (optional) - The protocol to use when cloning and syncing the repo.
Currently "git" is the default and only supported protocol.

* remotebranch (optional) - The remote branch that the project will sync to.
Defaults to "master".  The "remotebranch" attribute is ignored if "revision" is
specified.

* revision (optional) - The specific revision (usually a git SHA) that the
project will sync to.  If "revision" is  specified then the "remotebranch"
attribute is ignored.

* gerrithost (optional) - The url of the Gerrit host for the project.  If
specified, then running "jiri cl mail" will upload a CL to this Gerrit host.

* githooks (optional) - The path (relative to $JIRI_ROOT) of a directory
containing git hooks that will be installed in the projects .git/hooks directory
during each update.

* runhook (optional) - The path (relate to $JIRI_ROOT) of a script that will be
run during each update.

The <tool> tags describe the tools that will be compiled and installed in
$JIRI_ROOT/.jiri_root/bin after each update.  The tools must be written in go,
and are identified by their package name and the project that contains their
code.  They are configured via the following attributes:

* name (required) - The name of the binary that will be installed in
  JIRI_ROOT/.jiri_root/bin

* package (required) - The name of the Go package that will be passed to "go
  build".

* project (required) - The name of the project that contains the source code
  for the tool.
