The "given" isn't actually given.

When you say

 planet create <dir>

then even if <dir> and a package installation happen to be the same on
the filesystem, `planet create' doesn't access <dir> through a `planet'
path, so relative paths in <dir> are unrelated to Planet paths at the
level of module paths.

One current proposal is to have `planet create' build documentation out
of a currently installed package, instead from an arbitrary directory.
