I've installed 3.2.0b6. In the documentation that comes
with it there's a small error on the Installation page
(/usr/share/doc/htdig-3.2.0b6/install.html on my system).
At the top of that page there's a link to "Notes
for particular operating systems" which uses this HTML code:
<a href="OSs">Notes for particular operating systems</a>
There should be a # before OSs - i.e., the code should be:
<a href="#OSs">Notes for particular operating systems</a>
I tried submitted this to the bug database (assuming that there'd
be a place for submitting errors in the documentation), but I got
a "Connection timed out - the remote host or network may be down"
message when I went to http://cgi.htdig.org/cgi-bin/htdig3
Hope this helps. Nice product by the way; I'm really enjoying
learning about it, and the documentation is fantastic.
