$PRGNAM: $PRGNAM (Emacs-lisp <-> Python)
$PRGNAM:
$PRGNAM: Pymacs is a powerful tool which, once started from Emacs, allows both-way
$PRGNAM: communication between Emacs Lisp and Python. Pymacs aims Python as an
$PRGNAM: extension language for Emacs rather than the other way around, and this
$PRGNAM: asymmetry is reflected in some design choices. Within Emacs Lisp code, one
$PRGNAM: may load and use Python modules. Python functions may themselves use Emacs
$PRGNAM: services, and handle Emacs Lisp objects kept in Emacs Lisp space.
