// linux_dumper.h: Define the google_breakpad::LinuxDumper class, which
// is a base class for extracting information of a crashed process. It
// was originally a complete implementation using the ptrace API, but
// has been refactored to allow derived implementations supporting both
// ptrace and core dump. A portion of the original implementation is now
// in google_breakpad::LinuxPtraceDumper (see linux_ptrace_dumper.h for
// details).
