//  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.
