So that a package may be re-used as a sub-package in another package without
having to re-write or otherwise fudge all the import statements in the import
package.

well, if i have:

/package1/
/package1/package2a/modulea
/package1/package2a/package2b/mobuleb

...then when package 2 is being used on its own, I could do the following in
moduleb:

from package2a.modulea import someclass

However, as soon as package2a is installed as a sub-package of package1, then
I'd have to change that import statement to:

from package1.package2a.modulea import someclass

...or am I missign something?

cheers,

Chris
