New predicates (known as "aliases") can be defined, using any combination of
existing predicates or other aliases. An alias definition looks like::

  <alias> = <definition>

in the ``revsetalias`` section of ``.hgrc``. Arguments of the form `$1`, `$2`,
etc. are substituted from the alias into the definition.

For example,

::

  [revsetalias]
  h = heads()
  d($1) = sort($1, date)
  rs($1, $2) = reverse(sort($1, $2))

defines three aliases, ``h``, ``d``, and ``rs``. ``rs(0:tip, author)`` is
exactly equivalent to ``reverse(sort(0:tip, author))``.
