14# The checklist editor dialog.
15#
16# This module implements the checklist editor dialog. A checklist is a list of
17# sound files that are played one-by-one when requested by the user. The top
18# part of the dialog contains an aircraft type selector. Below it, on the left
19# there is a file selector, and the list of the files in the checklist to the
20# right. There are some buttons in the middle to manipulate the checklist.
