?X:
?X:	This was originally specific to perl5.  Since perl5 has man pages that
?X:	go in both man1/ and man3/ directories, we need both man1dir
?X:	and man3dir.  This unit is basically dist's mansrc.U with 
?X:	man3 used instead of man everywhere.
?X:	I then added various tests because perl5 has *lots* of man3 
?X:	pages with long file names. -- ADO

?S:man3dir:
?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:man3direxp:
?S:	This variable is the same as the man3dir variable, but is filename
?S:	expanded at configuration time, for convenient use in makefiles.
?S:.
?S:installman3dir:
?S:	This variable is really the same as man3direxp, unless you are using
?S:	AFS in which case it points to the read/write location whereas
?S:	man3direxp only points to the read-only access location. For extra
?S:	portability, you should only use this variable within your makefiles.
?S:.
?S:man3ext:
?S:	This variable contains the extension that the manual page should
?S:	have: one of 'n', 'l', or '3'.  The Makefile must supply the '.'.
?S:	See man3dir.

$spackage has manual pages for many of the library modules.

?X: thus man less will show the perl module less.pm, but not the system
?X: less command.  We might also conflict with TCL man pages.

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).
