?S:mansrc:
?S:	This variable contains the name of the directory in which manual
?S:	source pages are to be put.  It is the responsibility of the
?S:	Makefile.SH to get the value of this into the proper command.
?S:	You must be prepared to do the ~name expansion yourself.
?S:.
?S:mansrcexp:
?S:	This variable is the same as the mansrc variable, but is filename
?S:	expanded at configuration time, for convenient use in makefiles.
?S:.
?S:installmansrc:
?S:	This variable is really the same as mansrcexp, unless you are using
?S:	AFS in which case it points to the read/write location whereas
?S:	mansrcexp only points to the read-only access location. For extra
?S:	portability, you should only use this variable within your makefiles.
?S:.
?S:manext:
?S:	This variable contains the extension that the manual page should
?S:	have: one of 'n', 'l', or '1'.  The Makefile must supply the '.'.
?S:	See mansrc.

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