?S:sitearch:
?S:	This variable contains the eventual value of the SITEARCH symbol,
?S:	which is the name of the private library for this package.  It may
?S:	have a ~ on the front. It is up to the makefile to eventually create
?S:	this directory while performing installation (with ~ substitution).
?S:.
?S:sitearchexp:
?S:	This variable is the ~name expanded version of sitearch, so that you
?S:	may use it directly in Makefiles or shell scripts.
?S:.
?S:installsitearch:
?S:	This variable is really the same as sitearchexp but may differ on
?S:	those systems using AFS. For extra portability, only this variable
?S:	should be used in makefiles.
?S:.
?C:SITEARCH:
?C:	This symbol contains the name of the private library for this package.
?C:	The library is private in the sense that it needn't be in anyone's
?C:	execution path, but it should be accessible by the world.  The program
?C:	should be prepared to do ~ expansion.
?C:	The standard distribution will put nothing in this directory.
?C:	Individual sites may place their own extensions and modules in
?C:	this directory.
?C:.
?C:SITEARCH_EXP:
?C:	This symbol contains the ~name expanded version of SITEARCH, to be used
?C:	in programs that are not prepared to deal with ~ expansion at run-time.

The installation process will also create a directory for
architecture-dependent site-specific extensions and modules.

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