Slight variation, I get two lines:
<standard input>:23: a tab character is not allowed before an argument
<standard input>:33: a tab character is not allowed before an argument
followed by ^_ and other characters from the ascii art set :)

I remember you mentioned the possibility when you told me where man.cgi is.

Easy enough, and thanks for the explanation.
man man2html works after removing the two lines (with ee no less),
and still works after dragging it through man.cgi & man2html.

@ConvArgs = ("-topm", "0", "-botm", "0");
Fixed it thanks Mark.
It's good to have this working. Hyperlinked man pages are cool...
