CLI interface
=============

hare-wren includes the ``hwren`` command for running Wren programs with the
hare-wren runtime and :ref:`standard library <stdlib>`.

The command line interface is simple: use ``hwren <file.wren>`` to execute a
Wren script. The only other configurable parameter is the ``WRENPATH``
environment variable, which may be used to override the default import paths
(usually ``/usr/src/wren`` or similar) with a colon-delimited set of
alternative paths.
