Thanks a lot Rob. You made my day. I will see to it that I poke around the code before posting anything on these lines so that I can share my understanding with others. I did try to see any command lines options but didn't find any. </P?

And as per the snippet, a successfully "require" of the module leads to setting of install_html and returning a conditional true/false from DocTools is not a good idea. I will see if I can find an external way to switch on/off html gen.
