Gonz, the reason I never read the fecking manual is that it's just a
shopping list of features and how to enable/disable them. All the
features, whether super useful or just trivial, are lumped together.
Reading through that is tedious and sleep-inducing.

What the manual largely lacks is any description of _why_ you'd want
to use the features. So you need to scan the PDML and hope that you
can spot that useful piece of information floating amongst the
butt-nuggets of overly tight y-fronts and butch automobiles.

I have the PDML to thank for my finally engaging back-focus, and
discovering how useful the green button is for metering with vintage
glass, among many other things.
