  Huh ... I can't seem to locate when the actual command realpath was first
included in Linux.  The information I found made it seem to be a Debian-only
thing (I don't run Debian) but other information seems to contradict that. 
Only my main Linux system at home doesn't have the program realpath (but the
function realpath() exists in libc).

  -spc (So ... it may or may not exist on any given Linux system, is what
	I'm trying to say ... )
