 Previous versions of Autoconf promoted the name `',
which is somewhat ambiguous (the tool needed to process this file is not
described by its extension), and introduces a slight confusion with
`' and so on (for which `.in' means "to be processed by
`configure'").  Using `' is now preferred.

In a nutshell:|in's are to be processed by autoconf.
'*.in's in general, however are being processed by other tools
(typically configure, rsp. config.status)

Using the name enables you to apply file extension based
processing (eg. suffix-rules in Makefiles) to|ins.
