You should only use package.skeleton once, when you first decide to turn
your code into a package. After that, the assumption is that you will
manually edit the files.
If you call it later, it will not make use of all the work you did on
the previous attempt.
However, looking at the source, I don't see it ever writing import()
lines to the namespace. I think you must be mistaken about what it is
