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

This program is intended as a successor to the xphoon program (X PHase of mOON). xphoon is a program that displays the actual phase of the moon on the X11 root window. Nowadays many desktop systems like KDE hide the X11 root window with a background image of their own, so the xphoon output is not visible. When called, pngphoon creates a PNG image with the current phase of the moon. It can be used with window managers that allow using a command to provide a background image.
