Way back in the Swarm primordial ooze, the `space' library was deemed
an `additional' library on top of the main Swarm libraries (defobj,
activity, etc.) and in the old default `Makefile.conf' (oldtimers
remember those days before autoconf/automake... <sigh>) `-lspace' was,
by default, not included at link time.  Hence the need to add it the
application APPLIBS variable.

Now,`-lspace' comes as part of the shrink-wrapped `-lswarm'
convenience library and hence no need to supply it yourself.

The APPLIBS included in all the tutorial apps were removed last year
(and are obviously not in swarmapps-2.1):
