I'm not sure if this fits your bill (since texinfo is one step removed
from plain info), but it won't hurt advertising this piece of code again:
I have written a texinfo to html converter in Python. Python is an
object-oriented interpreted language (also written by me). The html
converter is part of the Python source distribution (in demo/www); you
can ftp this distribution from ftp.cwi.nl, directory pub/python, file
python0.9.8.tar.Z. It runs on most UNIX platforms.
If you have a Sparc or SGI platform, I can make a binary of just the
texinfo-to-html program available for you; this would save you the
trouble of building Python just to run the script, but means you can't
modify the program (the html it generates may need some
customization). Let me know if you're interested in this.
