Thanks for answering Bob!

I hope things are well in the Great State of Texas today!

OK, so an existing program, linked to version 0.0.0, will continue to
use the old version of the library? 

That implies that when I install a new version, the old version says
around. Is that correct?

Then, if the user re-links his program, the linker will find the most
recent version of the library to link to? Is that correct?

Thanks!

Ed

PS - I have some more complicated questions about versioning, but
first I want to be sure I understand the simplest cases.
