"""This module provides two functions, very similar to
EasyDialogs.AskFileForOpen() and EasyDialogs.AskFolder(): GetFile() and
GetFileOrFolder(). The main difference is that the functions here fully
support "packages" or "bundles", ie. folders that appear to be files in
the finder and open/save dialogs. The second difference is that
GetFileOrFolder() allows the user to select a file _or_ a folder.
