In HyperCard if you did a 'start using' you had access to all of the
resources in that stack.  I had just assumed that RunRev followed that
model and have been using it that way.  My vote is for for "feature" --
it's somewhat anagous to using include libraries in other programming
languages and makes reusing code pretty easy.
