Scx is an interface to Xlib for the Scheme implementation scsh. Scx is based on the Xlib interface of Elk 3.0 and shares most of the original API. In addition, scx provides bindings to the xft library for font rendering. Please report bugs to scsh-bugs@zurich.ai.mit.edu. See the file INSTALL for installation instructions. The installation procedure will produce a new executable "scx" that replaces the "scsh" executable and an image "scx.image" that the scx executable will load. Later versions of scx will provide a more convenient way of building the system. There is currently no documentation specific to scx but the description of the original Elk API at http://www-rn.informatik.uni-bremen.de/software/elk/doc.html might be helpful.
