+// EXC_BAD_ACCESS) occurs, it will be handled by the BreakpadRef
+// object as follows:
+//
+// 1. Create a minidump file (see Breakpad for details)
+// 2. Prompt the user (using CFUserNotification)
+// 3. Invoke a command line reporting tool to send the minidump to a
+//    server
+//

+// Key Abstractions
+// ----------------
+// 
+// This file declares multiple classes and protocols that are used by the 
+// GTMLogger logging system. The 4 main abstractions used in this file are the
+// following:
+//
+//   * logger (GTMLogger) - The main logging class that users interact with. It
+//   has methods for logging at different levels and uses a log writer, a log
+//   formatter, and a log filter to get the job done.
+// 
+//   * log writer (GTMLogWriter) - Writes a given string to some log file, where
+//   a "log file" can be a physical file on disk, a POST over HTTP to some URL,
+//   or even some in-memory structure (e.g., a ring buffer).
+//
+//   * log formatter (GTMLogFormatter) - Given a format string and arguments as
+//   a va_list, returns a single formatted NSString. A "formatted string" could
+//   be a string with the date prepended, a string with values in a CSV format,
+//   or even a string of XML.
+//
+//   * log filter (GTMLogFilter) - Given a formatted log message as an NSString
+//   and the level at which the message is to be logged, this class will decide
+//   whether the given message should be logged or not. This is a flexible way
+//   to filter out messages logged at a certain level, messages that contain
+//   certain text, or filter nothing out at all. This gives the caller the
+//   flexibility to dynamically enable debug logging in Release builds.
+//
+// This file also declares some classes to handle the common log writer, log
+// formatter, and log filter cases. Callers can also create their own writers, 
+// formatters, and filters and they can even build them on top of the ones
+// declared here. Keep in mind that your custom writer/formatter/filter may be
+// called from multiple threads, so it must be thread-safe.
+
+#import <Foundation/Foundation.h>
+
+// Predeclaration of used protocols that are declared later in this file.

+
+// GTMLogger
+//
+// GTMLogger is the primary user-facing class for an object-oriented logging
+// system. It is built on the concept of log formatters (GTMLogFormatter), log
+// writers (GTMLogWriter), and log filters (GTMLogFilter). When a message is
+// sent to a GTMLogger to log a message, the message is formatted using the log
+// formatter, then the log filter is consulted to see if the message should be
+// logged, and if so, the message is sent to the log writer to be written out.
+// 
+// GTMLogger is intended to be a flexible and thread-safe logging solution. Its
+// flexibility comes from the fact that GTMLogger instances can be customized
+// with user defined formatters, filters, and writers. And these writers,
+// filters, and formatters can be combined, stacked, and customized in arbitrary
+// ways to suit the needs at hand. For example, multiple writers can be used at
+// the same time, and a GTMLogger instance can even be used as another
+// GTMLogger's writer. This allows for arbitrarily deep logging trees.
+// 
+// A standard GTMLogger uses a writer that sends messages to standard out, a
+// formatter that smacks a timestamp and a few other bits of interesting
+// information on the message, and a filter that filters out debug messages from
+// release builds. Using the standard log settings, a log message will look like
+// the following:
+//
+//   2007-12-30 10:29:24.177 myapp[4588/0xa07d0f60] [lvl=1] foo=<Foo: 0x123>
+// 
+// The output contains the date and time of the log message, the name of the
+// process followed by its process ID/thread ID, the log level at which the
+// message was logged (in the previous example the level was 1:
+// kGTMLoggerLevelDebug), and finally, the user-specified log message itself (in
+// this case, the log message was @"foo=%@", foo).
+// 
+// Multiple instances of GTMLogger can be created, each configured their own
+// way.  Though GTMLogger is not a singleton (in the GoF sense), it does provide
+// access to a shared (i.e., globally accessible) GTMLogger instance. This makes
+// it convenient for all code in a process to use the same GTMLogger instance.
+// The shared GTMLogger instance can also be configured in an arbitrary, and
+// these configuration changes will affect all code that logs through the shared
+// instance.
+
+//
+// Log Levels
+// ----------
+// GTMLogger has 3 different log levels: Debug, Info, and Error. GTMLogger
+// doesn't take any special action based on the log level; it simply forwards
+// this information on to formatters, filters, and writers, each of which may
+// optionally take action based on the level. Since log level filtering is
+// performed at runtime, log messages are typically not filtered out at compile
+// time.  The exception to this rule is that calls to the GTMLoggerDebug() macro
+// *ARE* filtered out of non-DEBUG builds. This is to be backwards compatible
+// with behavior that many developers are currently used to. Note that this
+// means that GTMLoggerDebug(@"hi") will be compiled out of Release builds, but
+// [[GTMLogger sharedLogger] logDebug:@"hi"] will NOT be compiled out.
+// 
+// Standard loggers are created with the GTMLogLevelFilter log filter, which
+// filters out certain log messages based on log level, and some other settings.
+// 
+// In addition to the -logDebug:, -logInfo:, and -logError: methods defined on
+// GTMLogger itself, there are also C macros that make usage of the shared
+// GTMLogger instance very convenient. These macros are:
+//
+//   GTMLoggerDebug(...)
+//   GTMLoggerInfo(...)
+//   GTMLoggerError(...)
+//
+// Again, a notable feature of these macros is that GTMLogDebug() calls *will be
+// compiled out of non-DEBUG builds*.
+//
+// Standard Loggers
+// ----------------
+// GTMLogger has the concept of "standard loggers". A standard logger is simply
+// a logger that is pre-configured with some standard/common writer, formatter,
+// and filter combination. Standard loggers are created using the creation
+// methods beginning with "standard". The alternative to a standard logger is a
+// regular logger, which will send messages to stdout, with no special
+// formatting, and no filtering.
+//
+// How do I use GTMLogger?
+// ----------------------
+// The typical way you will want to use GTMLogger is to simply use the
+// GTMLogger*() macros for logging from code. That way we can easily make
+// changes to the GTMLogger class and simply update the macros accordingly. Only
+// your application startup code (perhaps, somewhere in main()) should use the
+// GTMLogger class directly in order to configure the shared logger, which all
+// of the code using the macros will be using. Again, this is just the typical
+// situation.
+// 
+// To be complete, there are cases where you may want to use GTMLogger directly,
+// or even create separate GTMLogger instances for some reason. That's fine,
+// too.
+//
+// Examples
+// --------
+// The following show some common GTMLogger use cases.
+//
+// 1. You want to log something as simply as possible. Also, this call will only
+//    appear in debug builds. In non-DEBUG builds it will be completely removed.
+//
+//      GTMLoggerDebug(@"foo = %@", foo);
+//
+// 2. The previous example is similar to the following. The major difference is 
+//    that the previous call (example 1) will be compiled out of Release builds
+//    but this statement will not be compiled out.
+//
+//      [[GTMLogger sharedLogger] logDebug:@"foo = %@", foo];
+//
+// 3. Send all logging output from the shared logger to a file. We do this by
+//    creating an NSFileHandle for writing associated with a file, and setting 
+//    that file handle as the logger's writer.
+//
+//      NSFileHandle *f = [NSFileHandle fileHandleForWritingAtPath:@"/tmp/f.log"
+//                                                          create:YES];
+//      [[GTMLogger sharedLogger] setWriter:f];
+//      GTMLoggerError(@"hi");  // This will be sent to /tmp/f.log
+//
+// 4. Create a new GTMLogger that will log to a file. This example differs from
+//    the previous one because here we create a new GTMLogger that is different
+//    from the shared logger.
+//
+//      GTMLogger *logger = [GTMLogger standardLoggerWithPath:@"/tmp/temp.log"];
+//      [logger logInfo:@"hi temp log file"];
+//
+// 5. Create a logger that writes to stdout and does NOT do any formatting to
+//    the log message. This might be useful, for example, when writing a help
+//    screen for a command-line tool to standard output.
+//      
+//      GTMLogger *logger = [GTMLogger logger];
+//      [logger logInfo:@"%@ version 0.1 usage", progName];
+//
+// 6. Send log output to stdout AND to a log file. The trick here is that 
+//    NSArrays function as composite log writers, which means when an array is 
+//    set as the log writer, it forwards all logging messages to all of its
+//    contained GTMLogWriters.
+//
+//      // Create array of GTMLogWriters
+//      NSArray *writers = [NSArray arrayWithObjects:
+//          [NSFileHandle fileHandleForWritingAtPath:@"/tmp/f.log" create:YES],
+//          [NSFileHandle fileHandleWithStandardOutput], nil];
+//      
+//      GTMLogger *logger = [GTMLogger standardLogger];
+//      [logger setWriter:writers];
+//      [logger logInfo:@"hi"];  // Output goes to stdout and /tmp/f.log
+//
+// For futher details on log writers, formatters, and filters, see the
+// documentation below.
+//
+// NOTE: GTMLogger is application level logging.  By default it does nothing
+// with _GTMDevLog/_GTMDevAssert (see GTMDefines.h).  An application can choose
+// to bridge _GTMDevLog/_GTMDevAssert to GTMLogger by providing macro
+// definitions in its prefix header (see GTMDefines.h for how one would do

+// DISCUSSION:
+//
+// The three main classes of interest are
+//
+//  MachMessage:    a wrapper for a mach message of the following form
+//   mach_msg_header_t
+//   mach_msg_body_t
+//   optional descriptors
+//   optional extra message data
+//
+//  MachReceiveMessage and MachSendMessage subclass MachMessage
+//    and are used instead of MachMessage which is an abstract base class
+//
+//  ReceivePort:
+//    Represents a mach port for which we have receive rights
+//
+//  MachPortSender:
+//    Represents a mach port for which we have send rights
+//
+// Here's an example to receive a message on a server port:
+//
+//        // This creates our named server port
+//        ReceivePort receivePort("com.Google.MyService");
+//
+//        MachReceiveMessage message;
+//        kern_return_t result = receivePort.WaitForMessage(&message, 0);
+//
+//        if (result == KERN_SUCCESS && message.GetMessageID() == 57) {
+//          mach_port_t task = message.GetTranslatedPort(0);
+//          mach_port_t thread = message.GetTranslatedPort(1);
+//
+//          char *messageString = message.GetData();
+//
+//          printf("message string = %s\n", messageString);
+//        }
+//
+// Here is an example of using these classes to send a message to this port:
+//
+//    // send to already named port
+//    MachPortSender sender("com.Google.MyService");
+//    MachSendMessage message(57);      // our message ID is 57
+//
+//    // add some ports to be translated for us
+//    message.AddDescriptor(mach_task_self());     // our task
+//    message.AddDescriptor(mach_thread_self());   // this thread
+//
+//    char messageString[] = "Hello server!\n";
+//    message.SetData(messageString, strlen(messageString)+1);

+// It has the additional limitation of having a fairly small fixed capacity of

+// But these dictionary classes may call malloc() during get and set operations.
