?S:scriptdir:
?S:	This variable holds the name of the directory in which the user wants
?S:	to put publicly scripts for the package in question.  It is either
?S:	the same directory as for binaries, or a special one that can be
?S:	mounted across different architectures, like /usr/share. Programs
?S:	must be prepared to deal with ~name expansion.

?S:scriptdirexp:
?S:	This variable is the same as scriptdir, but is filename expanded
?S:	at configuration time, for programs not wanting to bother with it.
?S:.
?S:installscript:
?S:	This variable is usually the same as scriptdirexp, unless you are on
?S:	a system running AFS, in which case they may differ slightly. You
?S:	should always use this variable within your makefiles for portability.
?S:.
?C:SCRIPTDIR:
?C:	This symbol holds the name of the directory in which the user wants

?C:	is often a directory that is mounted across diverse architectures.

?C:SCRIPTDIR_EXP:
?C:	This is the same as SCRIPTDIR, but is filename expanded at

Some installations have a separate directory just for executable scripts so
that they can mount it across multiple architectures but keep the scripts in
one spot.  You might, for example, have a subdirectory of /usr/share for this.
Or you might just lump your scripts in with all your other executables.

scriptdirexp="$ansexp"
if $afs; then
	$cat <<EOM

Since you are running AFS, I need to distinguish the directory in which
scripts reside from the directory in which they are installed (and from
which they are presumably copied to the former directory by occult means).
