[plt-scheme] Application distribution mechanisms ...

Hmmmm ... haven't thought about creating a .plt file yet.

The "distribution" executable option, I must say, is perfect for
most situations where you don't even want the user to be aware
that the application is written in Scheme.

The question of the runtime + small app package split is more
a problem of compatibility maintenance as I see it. Newer
versions, in that case, cannot break older code and so
it becomes difficult to throw away stuff.

I wouldn't really ask you guys to go out of your way
to officially bring back the older installation method, but it'll be  
to allow us to shoot ourselves in the foot if we want to ...  
unofficially :-P
