Differences bewteen Framework and Import ?

So, the statement
Framework brl.blitz will de facto import all the .bmx files contained in the brl.mod\blitz.mod directory ?

And the statement
Import brl.system
will import only the file brl.mod\system.mod\system.bmx ?

still quite confused. And yes, I've already noticed that 'Framework Assistant' by jb.
