RTL 3.0 RFE: set MANPATH to include rtl manpages

[Greg Ercolano <erco@3dsite.com>]

   On the RTL 3.0 CD, the default user environment 
   should likely include access the rtlinux manpages. 

   By default, they currently don't work, eg:
____________________________________________________________

% man rtf_get
No manual entry for rtf_get		%^(

% setenv MANPATH :/usr/rtlinux-3.0/rtldoc-3.0/man

% man rtf_get

rtf_get(3)				8^)

NAME
       rtf_get -- read data from a realtime fifo
:
:
____________________________________________________________

    On my own system I've added at the bottom of /etc/csh.cshrc:

	if ( $?MANPATH ) then
	    setenv MANPATH "${MANPATH}:/usr/rtlinux/man"
	else
	    setenv MANPATH :/usr/rtlinux/man
	endif

    ..and the following at the bottom of /etc/profile:

	if [ -z "$MANPATH" ]; then
	    export MANPATH=:/usr/rtlinux/man
	else
	    export MANPATH="${MANPATH}:/usr/rtlinux/man"
	fi

    This ensures all bash/csh/tcsh login accounts get working
    rtlinux manpages.

    Either that, or add the above settings to the appropriate
    files in /etc/skel/, eg. .cshrc and .bashrc.

    Also, so that commands like 'man -k rtl' work, similar 
    mods should likely be made to these cron files:

	/etc/cron.daily/makewhatis.cron
	/etc/cron.weekly/makewhatis.cron

    eg:

	#!/bin/bash
	LOCKFILE=/var/lock/makewhatis.lock
	if [ -z "$MANPATH" ]; then				####
	    export MANPATH=:/usr/rtlinux/man			  ##
	else							  ## ADD THESE
	    export MANPATH="${MANPATH}:/usr/rtlinux/man"	  ##
	fi							####
	[..snip..]
	makewhatis -w

    This way the makewhatis database picks up the rtlinux 
    manpages too.

    Note these settings do not break the default linux manpages; 
    the leading ':' ensures they are simply augmented.
