[m-dev.] For review: Simplified installation of user libraries

[Warwick Harvey]

Hi.  Sorry this took so long.  I tried to send it the night I was leaving 
for overseas, but a scheduled power disconnection in another building meant 
I lost the router for my subnet, and it wouldn't let me mail without at 
least doing a DNS lookup...  :-(

I also hope this hasn't been obsoleted by any of the 100 or so messages I 
haven't had a chance to read yet.  :-)

I couldn't think of good names, so I've "fixed" this by documentation.  :-)

... which you've now fixed.

There are a couple more bugs in the current bindist stuff.  In particular, 
the list of `realclean' targets in the samples and extras directory is way 
out of date.  In order to avoid the same problem happening again, I tried to 
fix this with a more general command:

        -dirs=`find ../samples/* ../extras/* -type d -print |   \
                        fgrep -v CVS | fgrep -v Mercury` &&     \
        for dir in $$dirs ; do                                  \
                ( cd $$dir ; mmake realclean )                  \
        done

However, when invoked from this Mmakefile, the `realclean' targets of at 
least one module (references/extras --- but I suspect others will also be 
affected similarly) do not function correctly, even though they work fine 
when invoked on their own.  The `global.realclean' target is not being 
invoked, only the recursive `realclean's.  I didn't have time to chase this 
down any further.

These fixes would probably best be separate changes anyway.

Anyway, here's a diff of the bindist changes.
