It's not at all well-tested yet (I made a lot of changes to it just tonight)
but it's late and I am literally sick (with flu) and tired so I'm checking
this in and going to bed.
Please fix all the bugs for me. ;-)
It now does a compatibility check of the environment as well,
including memory limits and so on - so this should reduce some
of the FAQs.
The text is still rough ... don't translate it just yet.
