Kevin,

Heh, Irony Oops! You typo'd the file extension (.kfcg) should be
.kcfg (that sequence of letters is always a tough one)

$ kde4-config --path kcfg
/home/sdowdy/.kde/share/config.kcfg/:/usr/share/kde4/config.kcfg/

While i'd just sort of discovered these in looking in more depth in
trying to determine where these might be found, i never even noticed
that there was a 'kcfg' path, and hadn't looked in detail...

Yep, cool.. (where's 'kxmleditor' when you need it? anybody know of
a good replacement XML visualization tool? )

So, i presume these files are simply compile-time reference material
when placed in that directory, and are not runtime referenced by the
application. (i.e. it's going to be up to the "distro" maintainer to
ensure they get put there so the average user can reference them, to
see what key values may have been default-overridden at compile-time
in the packaging.)

I see:  http://techbase.kde.org/Development/Tutorials/Using_KConfig_XT
as the reference.

Yeah, i used 'talk/write' a lot back in the mid 1980's, but haven't
used it except a couple times in the past decade.
