\subsection{ConTeXt compatibility} Currently not available. Volunteers for porting welcome. %\tkz and \chf are both compatible with ConTeXt. I don't know the first thing about ConTeXt myself, but thankfully Christian Tellechea, the author of \chf, has provided a plain-\TeX\ file with macros that should allow \mcf to work with ConTeXt. This file, \mcfplain, is also included with the archive and should be installed alongside \chf.
