I usually have to work with websites that are designed all graphically, using tables and IMG tags, that are non-validated... and I can't generate the right HTML using CGI.pm, so I run to making my own templates; the designer creates the template HTML, and I stuff it with comments that are then read by the script which substitutes the comments with desired values..

I know it's bad practice, but it saves me from maintaining the generated HTML to fit the designer's 'design' .
