+// ExceptionHandler can write a minidump file when an exception occurs,
+// or when WriteMinidump() is called explicitly by your program.
+//
+// To have the exception handler write minidumps when an uncaught exception
+// (crash) occurs, you should create an instance early in the execution
+// of your program, and keep it around for the entire time you want to
+// have crash handling active (typically, until shutdown).
+//
+// If you want to write minidumps without installing the exception handler,
+// you can create an ExceptionHandler with install_handler set to false,
+// then call WriteMinidump. You can also use this technique if you want to
+// use different minidump callbacks for different call sites.
+//
+// In either case, a callback function is called when a minidump is written,
+// which receives the unqiue id of the minidump. The caller can use this
+// id to collect and write additional application state, and to launch an
+// external crash-reporting application.
+//
+// It is important that creation and destruction of ExceptionHandler objects
+// be nested cleanly, when using install_handler = true.
+// Avoid the following pattern:
+// ExceptionHandler *e = new ExceptionHandler(...);
+// ExceptionHandler *f = new ExceptionHandler(...);
+// delete e;
+// This will put the exception filter stack into an inconsistent state.
