+Batched builds - compile faster
+instead of compiling object files one by one, c/c++ compilers are often able to compile at once:
+cc -c ../file1.c ../file2.c ../file3.c
+
+Files are output on the directory where the compiler is called, and dependencies are more difficult
+to track (do not run the command on all source files if only one file changes)
+
+As such, we do as if the files were compiled one by one, but no command is actually run:
+replace each cc/cpp Task by a TaskSlave
+A new task called TaskMaster collects the signatures from each slave and finds out the command-line
+to run.
+
+To set this up, the method ccroot::create_task is replaced by a new version, to enable batched builds
+it is only necessary to import this module in the configuration (no other change required)

+Configuration system
+
+A configuration instance is created when "waf configure" is called, it is used to:
+* create data dictionaries (Environment instances)
+* store the list of modules to import
+
+The old model (copied from Scons) was to store logic (mapping file extensions to functions)
+along with the data. In Waf a way was found to separate that logic by adding an indirection
+layer (storing the names in the Environment instances)
+
+In the new model, the logic is more object-oriented, and the user scripts provide the
+logic. The data files (Environments) must contain configuration data only (flags, ..).
+
+Note: the c/c++ related code is in the module config_c

+Node: filesystem structure, contains lists of nodes

+IMPORTANT:
+1. Each file/folder is represented by exactly one node.

+2. Most would-be class properties are stored in Build: nodes to depend on, signature, flags, ..
+unused class members increase the .wafpickle file size sensibly with lots of objects.

+3. The build is launched from the top of the build dir (for example, in _build_/).

+4. Node should not be instantiated directly.
+Each instance of Build.BuildContext has a Node subclass.

+"""
+Running tasks in parallel is a simple problem, but in practice it is more complicated:
+* dependencies discovered during the build (dynamic task creation)
+* dependencies discovered after files are compiled
+* the amount of tasks and dependencies (graph size) can be huge
+
+This is why the dependency management is split on three different levels:
+1. groups of tasks that run all after another group of tasks
+2. groups of tasks that can be run in parallel
+3. tasks that can run in parallel, but with possible unknown ad-hoc dependencies
+
+The point #1 represents a strict sequential order between groups of tasks, for example a compiler is produced
+and used to compile the rest, whereas #2 and #3 represent partial order constraints where #2 applies to the kind of task
+and #3 applies to the task instances.
+
+#1 is held by the task manager: ordered list of TaskGroups (see bld.add_group)
+#2 is held by the task groups and the task types: precedence after/before (topological sort),
+   and the constraints extracted from file extensions
+#3 is held by the tasks individually (attribute run_after),
+   and the scheduler (Runner.py) use Task::runnable_status to reorder the tasks
+
+--
+
+To try, use something like this in your code:
+import Constants, Task
+Task.algotype = Constants.MAXPARALLEL
+
+--
+
+There are two concepts with the tasks (individual units of change):
+* dependency (if 1 is recompiled, recompile 2)
+* order (run 2 after 1)
+
+example 1: if t1 depends on t2 and t2 depends on t3 it is not necessary to make t1 depend on t3 (dependency is transitive)
+example 2: if t1 depends on a node produced by t2, it is not immediately obvious that t1 must run after t2 (order is not obvious)
+
+The role of the Task Manager is to give the tasks in order (groups of task that may be run in parallel one after the other)

+The class task_gen encapsulates the creation of task objects (low-level code)
+The instances can have various parameters, but the creation of task nodes (Task.py)
+is delayed. To achieve this, various methods are called from the method "apply"
+
+The class task_gen contains lots of methods, and a configuration table:
+* the methods to call (self.meths) can be specified dynamically (removing, adding, ..)
+* the order of the methods (self.prec or by default task_gen.prec) is configurable
+* new methods can be inserted dynamically without pasting old code
+
+Additionally, task_gen provides the method apply_core
+* file extensions are mapped to methods: def meth(self, name_or_node)
+* if a mapping is not found in self.mappings, it is searched in task_gen.mappings
+* when called, the functions may modify self.allnodes to re-add source to process
+* the mappings can map an extension or a filename (see the code below)

+Java support
+
+Javac is one of the few compilers that behaves very badly:
+* it outputs files where it wants to (-d is only for the package root)
+* it recompiles files silently behind your back
+* it outputs an undefined amount of files (inner classes)
+
+Fortunately, the convention makes it possible to use the build dir without
+too many problems for the moment
+
+Inner classes must be located and cleaned when a problem arise,
+for the moment waf does not track the production of inner classes.
+
+Adding all the files to a task and executing it if any of the input files
+change is only annoying for the compilation times
+
+Compilation can be run using Jython[1] rather than regular Python. Instead of
+running one of the following commands:
+    ./waf configure
+    python waf configure
+You would have to run:
+    java -jar /path/to/jython.jar waf configure

+C/C++ preprocessor for finding dependencies
+
+Reasons for using the Waf preprocessor by default
+1. Some c/c++ extensions (Qt) require a custom preprocessor for obtaining the dependencies (.moc files)
+2. Not all compilers provide .d files for obtaining the dependencies (portability)
+3. A naive file scanner will not catch the constructs such as "#include foo()"
+4. A naive file scanner will catch unnecessary dependencies (change an unused header -> recompile everything)
+
+Regarding the speed concerns:
+a. the preprocessing is performed only when files must be compiled
+b. the macros are evaluated only for #if/#elif/#include
+c. the time penalty is about 10%
+d. system headers are not scanned
+
+Now if you do not want the Waf preprocessor, the tool "gccdeps" uses the .d files produced
+during the compilation to track the dependencies (useful when used with the boost libraries).
+It only works with gcc though, and it cannot be used with Qt builds. A dumb
+file scanner will be added in the future, so we will have most bahaviours.

+Utilities, the stable ones are the following:
+
+* h_file: compute a unique value for a file (hash), it uses
+  the module fnv if it is installed (see waf/utils/fnv & http://code.google.com/p/waf/wiki/FAQ)
+  else, md5 (see the python docs)
+
+  For large projects (projects with more than 15000 files) or slow hard disks and filesystems (HFS)
+  it is possible to use a hashing based on the path and the size (may give broken cache results)
+  The method h_file MUST raise an OSError if the file is a folder
+
+	import stat
+	def h_file(filename):
+		st = os.lstat(filename)
+		if stat.S_ISDIR(st[stat.ST_MODE]): raise IOError('not a file')
+		m = Utils.md5()
+		m.update(str(st.st_mtime))
+		m.update(str(st.st_size))
+		m.update(filename)
+		return m.digest()
+
+	To replace the function in your project, use something like this:
+	import Utils
+	Utils.h_file = h_file
+
+* h_list
+* h_fun
+* get_term_cols
+* ordered_dict
