Sorry for being thick about this, but such stuff is not covered in normal 
C++ text books.  It seems you have to learn it by word of mouth or maybe 
I need yet more books.

A single computational unit is  the files that are used to create any 
single object file?  That would be basically anything that would be 
#include (ed) in a source file?

Now what makes that interesting is that when I was studying templates, 
the declarations and definitions needed to be inside the same file.  How 
is that related (or the reason why it is not related)to the concept of a 
transitional unit?  And how does this affect the linking of shared 
libraries?
