     32 // The Exploitability class is an abstract base class providing common
     33 // generic methods that apply to exploitability engines for specific platforms.
     34 // Specific implementations will extend this class by providing run
     35 // methods to fill in the exploitability_ enumeration of the ProcessState
     36 // for a crash.
