Cool.

Yes, that is the case, but how could it be otherwise? If you load an
XML document, you have to, uh, load the XML document.

My first question is, have you actually done any performance
measurements? Take one of your pipelines that uses two of the steps
From a big library and time it. Then make a new library that only
contains those two steps and time that. Is the difference really
significant?

If it is, can you divide your big library into several smaller ones,
and is that sufficient?

I suppose if it's really a concern, it would be important to do some
measurments of Calabash and see what takes time.
