No, the findings aren't correct. You can manipulate the search path
directly.

import sys
sys.path.insert(0, "/directory/to/search")

will cause future imports to search /directory/to/search before all
other directories. Likewise, sys.append("/directory/to/search") will
search it after other directories.
