-// Class to manage crash handling and dumping.  When Enable is called, all
-// crashes will be caught and stored to the appropriate crash directory.
-// The directory will be:
-//   /home/chronos/user/crash - for all processes running as chronos
-//   /var/spool/crash - for all other processes
-// The class takes care of creating the directories (even recreating them
-// at crash time in case the cryptohome mounting changes from Enable time.
-//
-// For most use cases, there is no need to include or call any functions
-// explicitly in this header file.  Crash dumping is enabled just by linking
-// in libcrash_dumper.
