The C source files are in if-archive/programming/hugo/source at
ftp.gmd.de if you're interested in taking a look. Presumably a basic
port done with a sophisticated modern compiler wouldn't be all that
difficult (!) if one were to avoid the intricacies of turning it
into a state-of-the-art, magic-wand-operated Mac application.
Anyone interested can take a look at the source code, particularly
HCHEADER.H and HEHEADER.H, and get back to me.
Thanks.
