65overview = """\
66This class provides the file selection dialog. It incorporates OS-native features
67depending on the OS in use, and can be used both for open and save operations.
68The files displayed can be filtered by setting up a wildcard filter, multiple files
69can be selected (open only), and files can be forced in a read-only mode.
70
71There are two ways to get the results back from the dialog. GetFiles() returns only
72the file names themselves, in a Python list. GetPaths() returns the full path and
73filenames combined as a Python list.
74
75One important thing to note: if you use the file extension filters, then files saved
76with the filter set to something will automatically get that extension appended to them
77if it is not already there. For example, suppose the dialog was displaying the 'egg'
78extension and you entered a file name of 'fried'. It would be saved as 'fried.egg.'
79Yum!
