What I don't understand is why is it necessary to authomate all the installing.

I suppose it's not strictly necessary, merely highly desireable. There will always be a documented do-it-yourself method; it's the one that developers will use to bootstrap a CVS checkout into a working installation. But it will be much too hard for the average systems administrator to manage, requiring knowledge of Perl, Apache and database installation.

The rest of your message made very little sense to me... What do you mean by 'seen in intimacy'? What do 'structured to answer questions about PM' have to do with this topic?
