?S:localarch:
?S:	This variable contains the eventual value of the LOCALARCH 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:	This differs from $sitearch in that $sitearch is often
?S:	a shared network directory while $localarch is
?S:	at a local disk, because of policy/administrative issues
?S:	like for example caching (performance), licensing, or security.
?S:.
?S:localarchexp:
?S:	This variable is the ~name expanded version of localarch, so that you
?S:	may use it directly in Makefiles or shell scripts.
?S:.
?S:installlocalarch:
?S:	This variable is really the same as localarchexp but may differ on
?S:	those systems using AFS. For extra portability, only this variable
?S:	should be used in makefiles.
?S:.
?S:installlocalarchexp:
?S:	This variable is the ~name expanded version of installlocalarch,
?S:	so that you may use it directly in Makefiles or shell scripts.
?S:.
?C:LOCALARCH:
?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:	Local administration may place extensions and modules in
?C:	this directory.
?C:	This differs from SITEARCH in that SITEARCH is often
?C:	a shared network directory while LOCALARCH is
?C:	at a local disk, because of policy/administrative issues
?C:	like for example caching (performance), licensing, or security.
?C:.
?C:LOCALARCH_EXP:
?C:	This symbol contains the ~name expanded version of LOCALARCH,
?C:	to be used in programs that are not prepared to deal with ~
?C:	expansion at run-time.

The installation process will also create a directory for
architecture-dependent extensions and modules to be installed
alongside $locallib.

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