* ``--erasing <LP_FILE>`` where ``<LP_FILE>`` contains a sequence of builtin declarations like for the option ``--renaming`` except that, this time, ``lp_id`` can be a qualified identifier. It has the same effect as the option ``--renaming`` plus it removes any declaration of the renamed symbols. ``coq_expr`` therefore needs to be defined in Coq standard library or in the Coq file specified with the option ``-requiring``. It is not necessary to have entries for the symbols corresponding to the builtins ``"El"`` and ``"Prf"`` declared with the option ``--encoding`` since they are erased automatically. Example: `erasing.lp <https://github.com/Deducteam/lambdapi/blob/master/libraries/erasing.lp>`__.

* ``--use-notations`` instructs Lambdapi to use the usual Coq notations for the symbols corresponding to the builtins ``"eq"``, ``"not"``, ``"and"`` and ``"or"``.
