    supported:

    :``%%``: literal "%" character
    :``%s``: basename of file being printed
    :``%d``: dirname of file being printed, or '.' if in repository root
    :``%p``: root-relative path name of file being printed
    :``%H``: changeset hash (40 hexadecimal digits)
    :``%R``: changeset revision number
    :``%h``: short-form changeset hash (12 hexadecimal digits)
    :``%r``: zero-padded changeset revision number
    :``%b``: basename of the exporting repository
    :``\``: literal "\" character

    .. container:: verbose

      Template:

      The following keywords are supported in addition to the common template
      keywords and functions. See also :hg:`help templates`.
