One reason to follow the principle in general is that any mention of
the mechanics detracts from the content proper. Instructions take up
space. The canonical URL:
http://www.w3.org/Provider/Style/NoMechanics.html
Another reason to follow the principle in this case is the difficulty
of writing the instructions. Since all but the most basic instructions
would necessarily be system-dependent, one set of instructions would
not be sufficient. They would also be incomplete, because to cover all
platforms, all browsers, and all users is not feasible. Brief
instructions are probably useless: those who know what to do don't
need any instruction and those who don't know what to do require fairly
detailed instruction, instruction they can find either in the manual
for their own system or in one of the webpages *about* PDF reading on
the WWW.
