I'd much rather see this as "include=/some/path.d" where we read all
files ending with .cfg and .conf if it's a directory, or the file if
it's a fail, and then parse each include'd file in order of
   include-statement -> lexicographical order
so that

include=/etc/nagios.conf.d/
include=/etc/nagios.perfdata.d/

would cause all files from /etc/nagios.conf.d to be parsed before all
files from /etc/nagios.perfdata.d.

The included files can include other files, if they're so inclined.

Considering the successes of the wars on alcohol, poverty, drugs and
terror, I think we should give some serious thought to declaring war
on peace.
