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