?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.
