  10SYNOPSIS
  11--------
  12'git-send-pack' [--all] [--force] [--exec=<git-receive-pack>] [<host>:]<directory> [<ref>...]
  13
  14DESCRIPTION
  15-----------
  16Invokes 'git-receive-pack' on a possibly remote repository, and
  17updates it from the current repository, sending named refs.
  18
  19
  20OPTIONS
  21-------
  22--exec=<git-receive-pack>::
  23        Path to the 'git-receive-pack' program on the remote
  24        end.  Sometimes useful when pushing to a remote
  25        repository over ssh, and you do not have the program in
  26        a directory on the default $PATH.
  27
  28--all::
  29        Instead of explicitly specifying which refs to update,
  30        update all refs that locally exist.
  31
  32--force::
  33        Usually, the command refuses to update a remote ref that
  34        is not an ancestor of the local ref used to overwrite it.
  35        This flag disables the check.  What this means is that
  36        the remote repository can lose commits; use it with
  37        care.
  38
  39<host>::
  40        A remote host to house the repository.  When this
  41        part is specified, 'git-receive-pack' is invoked via
  42        ssh.
  43
  44<directory>::
  45        The repository to update.
  46
  47<ref>...:
  48        The remote refs to update.
  49
  50
  51Specifying the Refs
  52-------------------
  53
  54There are three ways to specify which refs to update on the
  55remote end.
  56
  57With '--all' flag, all refs that exist locally are transfered to
  58the remote side.  You cannot specify any '<ref>' if you use
  59this flag.
  60
  61Without '--all' and without any '<ref>', the refs that exist
  62both on the local side and on the remote side are updated.
  63
  64When one or more '<ref>' are specified explicitly, it can be either a
  65single pattern, or a pair of such pattern separated by a colon
  66":" (this means that a ref name cannot have a colon in it).  A
  67single pattern '<name>' is just a shorthand for '<name>:<name>'.
  68
  69Each pattern pair consists of the source side (before the colon)
  70and the destination side (after the colon).  The ref to be
  71pushed is determined by finding a match that matches the source
  72side, and where it is pushed is determined by using the
  73destination side.
  74
  75 - It is an error if <src> does not match exactly one of the
  76   local refs.
  77
  78 - It is an error if <dst> matches more than one remote refs.
  79
  80 - If <dst> does not match any remote ref, either
  81
  82   * it has to start with "refs/"; <dst> is used as the
  83     destination literally in this case.
  84
  85   * <src> == <dst> and the ref that matched the <src> must not
  86     exist in the set of remote refs; the ref matched <src>
  87     locally is used as the name of the destination.
  88
  89Without '--force', the <src> ref is stored at the remote only if
  90<dst> does not exist, or <dst> is a proper subset (i.e. an
  91ancestor) of <src>.  This check, known as "fast forward check",
  92is performed in order to avoid accidentally overwriting the
  93remote ref and lose other peoples' commits from there.
  94
  95With '--force', the fast forward check is disabled for all refs.
  96
  97Optionally, a <ref> parameter can be prefixed with a plus '+' sign
  98to disable the fast-forward check only on that ref.
