37/**
38 * The VBoxProblemReporter class is a central place to handle all problem/error
39 * situations that happen during application runtime and require the user's
40 * attention.
41 *
42 * The role of this class is to describe the problem and/or the cause of the
43 * error to the user and give him the opportunity to select an action (when
44 * appropriate).
45 *
46 * Every problem sutiation has its own (correspondingly named) method in this
47 * class that takes a list of arguments necessary to describe the situation and
48 * to provide the appropriate actions. The method then returns the choice to the
49 * caller.
