In other words, besides performing many useful tasks, Blub Shell is highly portable. In fact it is so portable, that it may be incorporated into MoreAbstract Shell.
There is of course a bit more to the story. MoreAbstract Shell only runs on OS W, but Blub Shell runs on OS X, L, and U. Furthermore, Blub Shell has an extensive collection of utility features which have been added on over the years, so there is much more plug and play code.
On the other hand, why wouldn't one choose the more abstract shell, if it was available?
