+ * From GCC docs: "You may use __builtin_expect to provide the compiler with branch prediction information. In general, you should prefer to use actual profile feedback for this (-fprofile-arcs), as programmers are notoriously bad at predicting how their programs actually perform. However, there are applications in which this data is hard to collect.
+ * 
+ * The return value is the value of exp, which should be an integral expression. The value of c must be a compile-time constant. The semantics of the built-in are that it is expected that exp == c."

+ * 
+ * BM_EXPECTED [...] is used to provide the compiler with branch prediction information for conditional statements.
+ * 
+ * An example of an appropriate use is parameter validation checks at the start of a function, such as <span class="code nobr">(aPtr == NULL)</span>. Since callers are always expected to pass a valid pointer, the likelihood of the conditional evaluating to true is extremely unlikely. This allows the compiler to schedule instructions to minimize branch miss-prediction penalties. For example:
+ <div class="sourcecode">if(BM_EXPECTED((aPtr == NULL), 0)) { abort(); }</div>
+ *
+ * @note If a compiler other than GCC 4+ is used then the macro leaves the conditional expression unaltered.

+ * <hr>
+ * @par Introduction
+ *
+ * BMScript is an Objective-C class set to make it easier to utilize the
+ * power and flexibility of a whole range of scripting languages that already
+ * come with modern Macs. BMScript does not favor any particular scripting
+ * language or UNIX™ command line tool for that matter, instead it was written
+ * as an abstraction layer to NSTask, and as such supports any command line tool,
+ * provided that it is available on the target system.
+ *
+ * @par Usage
+ *
+ * BMScript can be used in two ways:
+ *
+ * -# Use it directly
+ * -# Guided by the BMScriptLanguageProtocol, make a subclass from it
+ *
+ * The easiest way to use BMScript is, of course, to instanciate it directly:
+ *
+ * @include bmScriptCreationMethods.m
+ *
+ * You typically use the designated initializer for which you supply the script
+ * source and script options yourself.<br>
+ * The options dictionary then looks like this:
+ *
+ * @include bmScriptOptionsDictionary.m
+ *
+ * There's two constant keys. These are the only keys you need to define values for.
+ * #BMScriptOptionsTaskLaunchPathKey stores the path to the tool's executable and
+ * #BMScriptOptionsTaskArgumentsKey is a nil-terminated variable list of parameters
+ * to be used as arguments to the task which will load and execute the tool found at
+ * the launch path specified for the other key.
+ *
+ * It is very important to note that the script source string should <b>NOT</b> be
+ * supplied in the array for the #BMScriptOptionsTaskArgumentsKey, as it will be added
+ * later by the class after performing tests and delegation which could alter the script
+ * in ways needed to safely execute it. This is in the delegate object's responsibility.
+ *
+ * A macro function called #BMSynthesizeOptions(path, args) is available to ease
+ * the declaration of the options.<br>
+ * Here is the definition:
+ *
+ * @include bmScriptSynthesizeOptions.m
+ *
+ * <div class="box important">
+ *      <div class="table">
+ *          <div class="row">
+ *              <div class="label cell">Important:</div>
+ *              <div class="message cell">
+ *                  Don't forget the <b>nil</b> at the end even
+ *                  if you don't need to supply any task arguments.
+ *              </div>
+ *          </div>
+ *      </div>
+ * </div>
+ *
+ * If you initialize BMScript directly without specifying options and script source
+ * (e.g. using <span class="sourcecode">[[%BMScript alloc] init]</span>) the options
+ * will default to <span class="sourcecode">BMSynthesizeOptions(@"/bin/echo", @"")</span>
+ * and the script source will default to <span class="sourcecode">@"'<script source placeholder>'"</span>.
+ *
+ * <div class="box warning">
+ *      <div class="table">
+ *          <div class="row">
+ *              <div class="label cell">Warning:</div>
+ *              <div class="message cell">
+ *                  If you let your end-users, the consumers of your application, supply the
+ *                  script source without defining exact task options this can be very dangerous as anything
+ *                  passed to <span class="sourcecode">/bin/echo</span> is not checked by default! This is a
+ *                  good reason to use the BMScriptDelegateProtocol methods for error/security checking or to
+ *                  subclass BMScript instead of using it directly.
+ *              </div>
+ *          </div>
+ *      </div>
+ *  </div>
+ *
+ * There are also convenience methods for the most common scripting languages, which have
+ * their options set to OS default values:
+ *
+ * @include bmScriptConvenienceMethods.m
+ *
+ * As you can see loading scripts from source files is also supported, including a small
+ * and lightweight template system.
+ *
+ * @par Templates
+ *
+ * Using templates can be a good way to add domain-specific problem solving to a class.
+ * To utilize the template system, three steps are required:
+ *
+ *   -# Initialize a BMScript instance with a template
+ *   -# Saturate template with values ("fill in the blanks")
+ *   -# Execute BMScript instance
+ *
+ * Here are the methods you use to saturate a BMScript template with values:
+ *
+ * @include bmScriptSaturateTemplate.m
+ *
+ * So how does a template look like then? We use standard text files which have special
+ * token strings bound to get replaced. If you are familiar with Ruby, the magic template token
+ * looks a lot like Ruby's double quoted string literal:
+ *
+ * @verbatim %{} @endverbatim
+ *
+ * If this pattern structure is empty it will be replaced in the order of occurrence. The first
+ * two saturate methods are good for this.
+ * If the magic tokens wrap other values, a more flexible dictionary based system can be used
+ * with the third saturate method. There, the magic tokens must wrap names of keys defined in the
+ * dictionary. The keys will correspond to what the replacement value will be. <br>
+ *
+ * Here is an example of a Ruby script template, which converts octal or hexadecimal values to their decimal representation:
+ *
+ * @include convertToDecimalTemplate.rb
+ *
+ * Here's a short example how you'd use keyword based templates:
+ *
+ * @include TemplateKeywordSaturationExample.m
+ *
+ * @par Subclassing BMScript
+ *
+ * You can also see BMScript as a sort of abstract superclass and customize its
+ * behaviour by making a subclass which knows about the details of the particular
+ * command line tool that you want to use. Your subclass must implement the
+ * BMScriptLanguageProtocol. It only has one required and one optional method:
+ *
+ * @include bmScriptLanguageProtocol.m
+ *
+ * The first method should return default values, e.g. for launch path and task arguments,
+ * which are sensible and specific to the command line tool your subclass wants to utilize.
+ * Here you may again use #BMSynthesizeOptions(path, args) as the options dictionary has the
+ * same format as shown above.
+ *
+ * The second (optional) method should provide a default script source containing commands to execute
+ * by the command line tool. If you do not implement this method the script source will be set
+ * to the default script source of BMScript (see above).
+ *
+ * If you subclass BMScript and do not use the designated initializer through which
+ * you supply options and script source yourself, the BMScriptLanguageProtocol-p.defaultOptionsForLanguage
+ * method will be called on your subclass. If it is missing an exception of type
+ * #BMScriptLanguageProtocolMethodMissingException is thrown.
+ *
+ * @par Execution
+ *
+ * After you have obtained and configured a BMScript instance, you need to tell it to execute.
+ * This can be done by telling it to excute synchroneously (blocking), or asynchroneously (non-blocking):
+ *
+ * @include bmScriptExecution.m
+ *
+ * Using the blocking execution model you can either pass a pointer to NSString where the result will be
+ * written to (including NSError if needed), or just use plain BMScript.execute. 
+ * This will return the TerminationStatus, or the return value the underlying process exited with.
+ * You can then obtain the script execution result by accessing BMScript.lastResult.
+ *
+ * The non-blocking execution model works by means of <a href="http://developer.apple.com/mac/library/documentation/Cocoa/Conceptual/CocoaFundamentals/CommunicatingWithObjects/CommunicateWithObjects.html#//apple_ref/doc/uid/TP40002974-CH7-SW7" class="external">notifications</a>.
+ * You register your class as observer with the default notification center for a notification called
+ * #BMScriptTaskDidEndNotification passing a selector to execute once the notification arrives. If you have
+ * multiple BMScript instances you can also pass the instance you want to register the notification for as
+ * the object paramater (see inline example below).
+ *
+ * Then you tell the BMScript instance to BMScript.executeInBackgroundAndNotify. When execution finishes and your
+ * selector is called it will be passed an NSNotification object which encapsulates an NSDictionary with two keys:
+ *
+ * <div class="box hasRows noshadow">
+ *      <div class="row odd firstRow">
+ *          <span class="cell left firstCell">#BMScriptNotificationTaskResults</span>
+ *          <span class="cell rightCell lastCell">contains the results returned by the execution as NSString.</span>
+ *      </div>
+ *      <div class="row even">
+ *          <span class="cell left firstCell">#BMScriptNotificationTaskTerminationStatus</span>
+ *          <span class="cell rightCell lastCell">contains the termination status (aka return/exit code)</span>
+ *      </div>
+ * </div>
+ *
+ * To make that clearer here's an example with the relevant parts thrown together:
+ *
+ * @include NonBlockingExecutionExample.m
+ *
+ * It is important to note at this point that the blocking and non-blocking tasks are tracked by seperate instance variables.
+ * This was done to minimize the risk of race conditions when BMScript would be used in a multi-threaded environment.
+ *
+ * @par On The Topic Of Concurrency
+ *
+ * All access to global data, shared variables and mutable objects has been
+ * locked with <a href="x-man-page://pthread" class="external">pthread_mutex_locks</a>
+ * (in Xcode: right-click and choose "Open Link in Browser").
+ * This is done by a macro wrapper which will avaluate to nothing if #BMSCRIPT_THREAD_SAFE is not 1.
+ * #BMSCRIPT_THREAD_SAFE will also set #BM_ATOMIC to 1 which will make all accessor methods atomic.
+ * Note that there haven't been enough tests yet to say that BMScript is thread-safe. 
+ *
+ * It is likely thread-safe enough, but still, care has to be taken when two different threads want to access
+ * internal state of the same BMScript instance. 
+ *
+ * BMScript was also designed such that re-use is possible. Unfortunately this does not automatically mean it's 
+ * intrinsically thread-safe or that it does promote re-entrant code. 
+ * You are encouraged to look through the source in order to determine if it may be thread-safe enough for your purpose.
+ *
+ * @par Delegate Methods
+ *
+ * BMScript also features a delegate protocol (BMScriptDelegateProtocol) providing descriptions for methods
+ * your subclass or another class posing as delegate can implement:
+ *
+ * @include bmScriptDelegateMethods.m
+ *
+ * @par Instance Local Execution History
+ *
+ * And last but not least, BMScript features an execution cache, called its history. This works like the Shell history
+ * in that it will keep script sources as well as the results of the execution of those sources.
+ * To access the history you may use the following methods:
+ *
+ * @include bmScriptHistory.m
+ *

+ * - You need to give your end-users the ability to supply script sources

+MGScopeBar
+By Matt Legend Gemmell
+http://mattgemmell.com/
+http://instinctivecode.com/
+
+
+
+What is MGScopeBar?
+-------------------
+
+MGScopeBar is a control which provides a "scope bar" or "filter bar", much like that found in iTunes, the Finder (in the Find/Spotlight window), and Mail.
+
+
+
+What platforms does it support?
+-------------------------------
+
+MGScopeBar supports Mac OS X 10.5 (Leopard) or later.
+
+
+
+What are the licensing requirements?
+------------------------------------
+
+A license documented is included with the source code, but essentially it's a BSD-like license but requiring attribution. You're free to use the code in any kind of project, commercial or otherwise. You're also free to redistribute it, either modified or as-is. Read the license document for more details, and contact me if you have questions.
+
+
+
+How do I use it in my project?
+------------------------------
+
+Just copy the five files whose names start with "MG" into your project, and you're good to go. You can also use the AppController class as a handy reference, since it provides a demo of how MGScopeBar works.
+
+
+
+What can it do?
+---------------
+
+MGScopeBar gives you a scope bar control which gets its data from a delegate; it's very like NSTableView and other similar controls, so you should find it easy to use.
+
+You can specify multiple "groups" of buttons, each of which can have:
+
+1. An optional separator before the group.
+
+2. An optional label to the left of the first button (and after the separator).
+
+3. A series of buttons, each of which has a title, unique identifier string, and optional icon.
+
+4. A selection-mode for the group; either radio-mode (only one item selected at a time), or multiple-selection (zero or more items can be selected at a time).
+
+Scope bars also support an optional accessory view, displayed at the right side of the bar.
+
+You can choose whether to use the Smart Resize feature (which is on by default). Smart Resize causes the scope bar to automatically collapse button-groups into popup-menus to better fit the available space.
+
+You should read the MGScopeBarDelegateProtocol.h file to see a list of the delegate methods your delegate object will need to implement.
+
+
+
+How do I know which buttons are selected in which groups?
+---------------------------------------------------------
+
+There's a delegate method which will be called whenever the user interacts with the scope bar in such a way as to change the selection in any group; see the delegate protocol (and the example code in AppController) for more details.
+
+You can also call the -selectedItems method on MGScopeBar to find out exactly what's selected at any time. See the MGScopeBar.h file for an explanation of the data returned from this method.
+
+
+
+Getting in touch
+----------------
+
+Whilst I can't provide specific help with integrating MGScopeBar into your application, I always welcome feedback, suggestions and bug reports. Feel free to get in touch with me via my gmail address (matt.gemmell) anytime.
+
+I hope you enjoy using MGScopeBar.

+- Maybe properly support a blue gradient appearance (like Mail in Tiger)?
+	- Easy to change background gradient, but buttons/popups still highlight gray.
+
+- Accessibility support
+	- The control needs to indicate which groups it contains, what selection-mode those groups support, etc.
+	- Otherwise it's just an opaque group of buttons to VoiceOver.
