Probably a lack of clarity on my part. The way I look at
it is:

If a letter is a directory (package) and a letter
and number is a module, then:

A is the grandfather
A.B is the father
A.B.B1 is the module that contains the import statement.
A.B.B2 is another module in the same package
A.B.D is a package that is a sibling of B1 and B2
A.B.D.D1 is a module in package D, and is therefore a nephew
A.C is an uncle (the father's sibling)
A.C.C1 is a cousin.
A.A1 is another uncle

* then refers to the package (directory) that
contains the module with the import statement.

^ refers to that package's parent directory.

*.B2 referes to a sibling of B1
^.C.C1 refers to a cousin of B1
^.A1 refers to a module in package A
*.D.D1 refers to the nephew D1

Hope this clarifies my way of looking at it.
