-//  This file defines a NSAutoreleasePoolChecker, a small checker that warns
-//  about subpar uses of NSAutoreleasePool.  Note that while the check itself
-//  (in its current form) could be written as a flow-insensitive check, in
-//  can be potentially enhanced in the future with flow-sensitive information.
-//  It is also a good example of the CheckerVisitor interface.
