The <A> tag allows you to insert a link that will lead the
reader to another location (perhaps in an entirely different
document).
Legal attributes for this tag include HREF (and
many more).
The Perl CGI construct for inserting an anchor would be:
# Try a hyperlink
print $query->hr();
print $query->a({-href=>'/killbill/images/xmms.jpg'},
"This is a link directly to the image of the basic",
" Linux MP3 player client");
print $query->hr();
Again, there are many options for controlling the behavior of
your link, all available from the Perl CGI routines.
