45 // Level description
46 //
47 // None - Function is no threat at all. It doesn't constitute
48 // an threat to either users or the system and has no
49 // known side effects
50 //
51 // Nuisance - Abuse of this command can cause a nuisance to the
52 // region operator, such as log message spew
53 //
54 // VeryLow - Extreme levels ob abuse of this function can cause
55 // impaired functioning of the region, or very gullible
56 // users can be tricked into experiencing harmless effects
57 //
58 // Low - Intentional abuse can cause crashes or malfunction
59 // under certain circumstances, which can easily be rectified,
60 // or certain users can be tricked into certain situations
61 // in an avoidable manner.
62 //
63 // Moderate - Intentional abuse can cause denial of service and crashes
64 // with potential of data or state loss, or trusting users
65 // can be tricked into embarrassing or uncomfortable
66 // situationsa.
67 //
68 // High - Casual abuse can cause impaired functionality or temporary
69 // denial of service conditions. Intentional abuse can easily
70 // cause crashes with potential data loss, or can be used to
71 // trick experienced and cautious users into unwanted situations,
72 // or changes global data permanently and without undo ability
73 //
74 // VeryHigh - Even normal use may, depending on the number of instances,
75 // or frequency of use, result in severe service impairment
76 // or crash with loss of data, or can be used to cause
77 // unwanted or harmful effects on users without giving the
78 // user a means to avoid it.
79 //
80 // Severe - Even casual use is a danger to region stability, or function
81 // allows console or OS command execution, or function allows
82 // taking money without consent, or allows deletion or
83 // modification of user data, or allows the compromise of
