https://github.com/redline6561/colorize/blob/master/colorize.lisp#L286 - this attempts to do (find-symbol thing :html-colorize), but I don't think :html-colorize names any package. The old code had :html-encode. Is that what it's supposed to be instead?
(find-symbol thing :html-colorize)
This issue breaks cl-gendoc-doc.
Crap. I'm a fool. Fixing it now. Thanks Xach.
Fix package-name thinko. Resolves Issue #2.
