?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: In 5.005_57 and earlier, I had the following notes:
?X: We dont use /usr/local/man/man3 because some man programs will
?X: only show the /usr/local/man/man3 contents, and not the system ones,
?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.
?X: However, something like /opt/perl/man/man3 is fine.
?X:
?X: However, opinion seems to be shifting such that 'man POSIX' ought
?X: to just work.  -- Andy Dougherty  July 8, 1999
?X:
?X: remove any trailing -3.0 or other version indification from $package
