// General debugging facilities

// - In developer level, all checking and debugging facilities are

// active.
|
|
//
|
|
// - Alpha level does not include performance degrading
|
|
// VALIDATE calls.
|
|
//
|
|
// - Beta level is like Alpha, but does not include debugging
|
|
// facilities.
|
|
//
|
|
// - Release level does not include CONFIRM checks, but does include
|
|
// assert calls.
|
|
//
|
|
// - Running with no seatbelt disables all checking except for normal
|
|
// syntax and semantic error checking.
