...and also, for your own and the operator's sanity, skip anything
else beginning with '.', names that don't end in ".conf" (or ".inetd"
or whatever you think the proper suffix should be), and anything that
isn't a regular file (DT_REG).
(If you get DT_UNKNOWN it's reasonable to call stat to get the real
type rather than just skipping it, and you might want to allow
symlinks, but definitely skip directories, devices, named pipes, etc.)
...also I strongly recommend against having global settings that are
meant to change around as things are included (such that the order
includes are processed in matters) -- you wouldn't write code that
used global variables that way, don't do it in configs...
