    The optional rootDir argument defines the directory to use for this
    new server installation. The directory will be created. By default,
    this server is non-Unicode and case-sensitive. The optional -c
    argument defines the branching structure to use other than //stream/*

    The optional rootDir argument defines the directory to use for this
    new server installation. The directory will be created. By default,
    this server is non-Unicode and case-sensitive.

    You can specify 'MYP4=userid $me clone ...' to specify the

    The first form calls the underlying p4 clone command and then

    $me switch -h                   List hidden streams

    Local branching is controlled using this command. The wrapper calls
    the underlying Perforce switch command for all of this functionality.

    With no arguments, it returns the name of the current stream.

    When called with the following arguments:
      -l returns the list of all streams
      -c creates a new stream of the specified name and populates it based
         on the current stream
      -cm create a new empty stream of the specified name
      -mc create a new empty stream of the specified name
      STREAM switches to the specified stream after shelving any pending
         work.

    The -d argument is used to hide a stream from being used or listed.
    No content is removed from the underlying storage and no remote
    mappings are changed. Use the -r option to restore a hidden stream.
    The -h argument is used to list out the hidden streams.
FOOBAR

		map)
			cat <<FOOBAR
    $me map
    $me map REMOTE_URL

    With no arguments, this returns the all mappings for the 
    remote server associated with the current stream. 

    The REMOTE_URL defines the mapping from the current stream and
    the specified location on a remote server. This mapping will be
    aggregated with any other mapping targeting the same remote
    server. The REMOTE_URL is in the following format:

            {userid@}{ssl:}host:port://depot_path

    If there is currently a map defined for this stream, then this 
    will replace that mapping with this new one.

    This is not a Perforce command. This is a wrapper around the
    'p4 remote' command.

    You may want to read '$me help remote' and '$me help remotes'

			;;
		push)
			cat <<FOOBAR
    $me push {-a}                   Push current stream to defined remote
    
    This command looks up the associated remote for this stream and
    invokes the underlying 'p4 push' command with the appropriate
    arguments. If there is pending work, then you will be asked if
    you want to submit or revert the changes. 

    The optional -a argument is used to push all streams associated
    with the remote linked to the current stream.

    Note: This wrapper obscures the underlying command
FOOBAR
			;;
		fetch)
			cat <<FOOBAR
    $me fetch {-a}                  Fetch from defined remote to current stream

    This command looks up the associated remote for this stream and
    invokes the underlying 'p4 fetch' command with the appropriate
    arguments. If there is pending work, then you will be asked if
    you want to submit or revert the changes. 

    The optional -a argument is used to fetch all streams associated
    with the remote linked to the current stream.

    Note: This wrapper obscures the underlying command
FOOBAR
			;;
		mergefrom)
			cat <<FOOBAR
    $me mergefrom STREAM            Run integ from named stream into current one

    This command runs 'p4 merge --from STREAM'. It then runs 'p4 resolve -as'. 
    This does not submit the merged and resolved files, you must do that manually.

    This is not a Perforce command. You may want to look at the help for
    p4 merge.
FOOBAR
			;;
		checkpoint)
			cat <<FOOBAR
    $me checkpoint {description}    Reconcile and submit if needed

			;;
		web)
			cat <<FOOBAR
    $me web                          Bring up p4web

    This command will either startup or shutdown a p4web browse instance
    running against the local server. This p4web is not network accessible.

    This is not a Perforce command.
FOOBAR
			;;
		server)

    $me server stop                 Shutdown the network acccessible p4d

    This command invokes p4d on the specified port or 1666 for use either
    by remote user or by some local client like p4eclipse or p4v. By
    default, the local server is restricted to only the individual user.
    Use the '$me allow' command to enable others to fetch from this 
    networked server.

    The 'stop' argument will shutdown this network accessible server.

    This is not yet a Perforce command.
FOOBAR
			;;
		allow)
			cat <<FOOBAR
    $me allow {-a} {USER PASSWORD {p}}   Allow user/password to fetch {and push}

    This command creates the named user and sets their password accordingly.
    The optional 'p' argument enables the named user to 'push' to this
    server and is not recommended except for testing purposes. 'push' 
		implies '-a' so all streams can be fetched and pushed to/from.

    The -a argument indicates that all streams should be accessible to the
    specified user. Without the -a, only the USER can only fetch from the
    current stream.

    With no arguments, this command lists the users which are currently
    allowed to fetch from this server when a networked server is running.

    This is not yet a Perforce command.
FOOBAR
			;;
		disallow)
			cat <<FOOBAR
    $me disallow {USER}             Disallow user from fetching

    This command removes the named user from the system along with all
    access rules defined for them. This removes all access for the 
    specified USER.

    With no arguments, this command lists the users which are currently
    allowed to fetch from this server when a networked server is running.

    This is not yet a Perforce command.
