I take it those who are so against file endings are equally upset by
sources.list and menu.lst?
Though it is very annoying when they are *needed*. Xsane usually puts them
in, and I used not to bother to check. A few months ago I sent my lawyer a
scan of a document he needed. An hour or two later, back came an
email: "I'm so sorry, we have no software that can open that file. The IT
department has been trying for an hour". Puzzled, because I thought I had
sent a .pdf, and had checked that it opened fine in Evince, I looked at the
file - groaned - and renamed scan-foo to scan-foo.pdf. When resent it opened
fine.
