(Overview): Add Peter Eriksson to the list of signficant
	contributors.  ISC was a piece of very important "enabling
	technology".
(Parameter Types): Mention that all files are absolute if the begin with '/'.
(Parameters): Use @var{} instead of @i{}.  Markup fixes and other
	minor typo fixes.  The "Log statistics" path is used when the
	server receives a SIGUSR1 signal -- not a SIGHUP!
(Aux-Item Definition File): The file name was wrong.  Don't use
	@i{}.  Document the "server" keyword.  Mention that permanent
	aux-items will be deleted when the object they belong to are
	deleted.
(Signals): Removed a note about SIGUSR2 not working on Suns.  It
	should work fine there as well.
(Files): Don't use @i{}.
