The Interactive HTMLab is a tool for demonstrating and
experimenting with HTML markup. It runs within a web browser,
using JavaScript and CGI. HTML documents may be created or marked
up on-the-fly, and the results immediately displayed or validated.
The Interactive HTMLab is implemented by the htmlab.cgi
CGI script. This script requires perl version 5 and the
LWP::UserAgent module.
Do not even consider retrieving this unless you are
reasonably competent with perl. All you are getting is a
bare script with no documentation. You will almost certainly need
to tailor it to work in your environment. For instance, the
do-validate.sh script (launched by the VALIDATE
button) almost certainly won't run as-is in your environment.
