  will come is in ``$HG_URL``.
``precommit``
  Run before starting a local commit. Exit status 0 allows the
  commit to proceed. Non-zero status will cause the commit to fail.
  Parent changeset IDs are in ``$HG_PARENT1`` and ``$HG_PARENT2``.
``preoutgoing``
  Run before collecting changes to send from the local repository to
  another. Non-zero status will cause failure. This lets you prevent
  pull over HTTP or SSH. Also prevents against local pull, push
  (outbound) or bundle commands, but not effective, since you can
  just copy files instead then. Source of operation is in
  ``$HG_SOURCE``. If "serve", operation is happening on behalf of remote
  SSH or HTTP repository. If "push", "pull" or "bundle", operation
  is happening on behalf of repository on same system.
``pretag``
  Run before creating a tag. Exit status 0 allows the tag to be
  created. Non-zero status will cause the tag to fail. ID of
  changeset to tag is in ``$HG_NODE``. Name of tag is in ``$HG_TAG``. Tag is
  local if ``$HG_LOCAL=1``, in repository if ``$HG_LOCAL=0``.

``preupdate``
  Run before updating the working directory. Exit status 0 allows
  the update to proceed. Non-zero status will prevent the update.
  Changeset ID of first new parent is in ``$HG_PARENT1``. If merge, ID
  of second new parent is in ``$HG_PARENT2``.
``tag``
  Run after a tag is created. ID of tagged changeset is in ``$HG_NODE``.
  Name of tag is in ``$HG_TAG``. Tag is local if ``$HG_LOCAL=1``, in
  repository if ``$HG_LOCAL=0``.

  Parent changeset IDs are in ``$HG_PARENT1`` and ``$HG_PARENT2``.
``prelistkeys``
  Run before listing pushkeys (like bookmarks) in the
  repository. Non-zero status will cause failure. The key namespace is
  in ``$HG_NAMESPACE``.

``prepushkey``
  Run before a pushkey (like a bookmark) is added to the
  repository. Non-zero status will cause the key to be rejected. The
  key namespace is in ``$HG_NAMESPACE``, the key is in ``$HG_KEY``,
  the old value (if any) is in ``$HG_OLD``, and the new value is in
  ``$HG_NEW``.

``listkeys``
  Run after listing pushkeys (like bookmarks) in the repository. The
  key namespace is in ``$HG_NAMESPACE``. ``$HG_VALUES`` is a
  dictionary containing the keys and values.
``pushkey``

  ``$HG_KEY``, the old value (if any) is in ``$HG_OLD``, and the new
  value is in ``$HG_NEW``.
``tag``
  Run after a tag is created. ID of tagged changeset is in ``$HG_NODE``.
  Name of tag is in ``$HG_TAG``. Tag is local if ``$HG_LOCAL=1``, in
  repository if ``$HG_LOCAL=0``.
