 Automatic Pooled Storage for Clones
 -----------------------------------
 
 When this extension is active, :hg:`clone` can be configured to
 automatically share/pool storage across multiple clones. This
 mode effectively converts :hg:`clone` to :hg:`clone` + :hg:`share`.
 The benefit of using this mode is the automatic management of
 store paths and intelligent pooling of related repositories.
 
 The following ``share.`` config options influence this feature:
 
 ``share.pool``
     Filesystem path where shared repository data will be stored. When
     defined, :hg:`clone` will automatically use shared repository
     storage instead of creating a store inside each clone.
 
 ``share.poolnaming``
     How directory names in ``share.pool`` are constructed.
 
     "identity" means the name is derived from the first changeset in the
     repository. In this mode, different remotes share storage if their
     root/initial changeset is identical. In this mode, the local shared
     repository is an aggregate of all encountered remote repositories.
 
     "remote" means the name is derived from the source repository's
     path or URL. In this mode, storage is only shared if the path or URL
     requested in the :hg:`clone` command matches exactly to a repository
     that was cloned before.
 
     The default naming mode is "identity."

        using rollback or extensions that destroy/modify history (mq,

        the same changeset, and one of them destroys that changeset

        operations will fail with "abort: working directory has unknown

        the broken clone to reset it to a changeset that still exists.
