-"""SCons.Action
-
-This encapsulates information about executing any sort of action that
-can build one or more target Nodes (typically files) from one or more
-source Nodes (also typically files) given a specific Environment.
-
-The base class here is ActionBase.  The base class supplies just a few
-OO utility methods and some generic methods for displaying information
-about an Action in response to the various commands that control printing.
-
-A second-level base class is _ActionAction.  This extends ActionBase
-by providing the methods that can be used to show and perform an
-action.  True Action objects will subclass _ActionAction; Action
-factory class objects will subclass ActionBase.
-
-The heavy lifting is handled by subclasses for the different types of
-actions we might execute:
-
-    CommandAction
-    CommandGeneratorAction
-    FunctionAction
-    ListAction
-
-The subclasses supply the following public interface methods used by
-other modules:
-
-    __call__()
-        THE public interface, "calling" an Action object executes the
-        command or Python function.  This also takes care of printing
-        a pre-substitution command for debugging purposes.
-
-    get_contents()
-        Fetches the "contents" of an Action for signature calculation
-        plus the varlist.  This is what gets MD5 checksummed to decide
-        if a target needs to be rebuilt because its action changed.
-
-    genstring()
-        Returns a string representation of the Action *without*
-        command substitution, but allows a CommandGeneratorAction to
-        generate the right action based on the specified target,
-        source and env.  This is used by the Signature subsystem
-        (through the Executor) to obtain an (imprecise) representation
-        of the Action operation for informative purposes.
-
-
-Subclasses also supply the following methods for internal use within
-this module:
-
-    __str__()
-        Returns a string approximation of the Action; no variable
-        substitution is performed.
-
-    execute()
-        The internal method that really, truly, actually handles the
-        execution of a command or Python function.  This is used so
-        that the __call__() methods can take care of displaying any
-        pre-substitution representations, and *then* execute an action
-        without worrying about the specific Actions involved.
-
-    get_presig()
-        Fetches the "contents" of a subclass for signature calculation.
-        The varlist is added to this to produce the Action's contents.
-
-    strfunction()
-        Returns a substituted string representation of the Action.
-        This is used by the _ActionAction.show() command to display the
-        command/function that will be executed to generate the target(s).
-
-There is a related independent ActionCaller class that looks like a
-regular Action, and which serves as a wrapper for arbitrary functions
-that we want to let the user specify the arguments to now, but actually
-execute later (when an out-of-date check determines that it's needed to
-be executed, for example).  Objects of this class are returned by an
-ActionFactory class that provides a __call__() method as a convenient
-way for wrapping up the functions.

-# A LazyAction is a kind of hybrid generator and command action for

-# strings (think "$CCCOM" to "$CC -c -o $TARGET $SOURCE"), but we also
-# want to be able to replace them with functions in the construction
-# environment.  Consequently, we want lazy evaluation and creation of
-# an Action in the case of the function, but that's overkill in the more
-# normal case of expansion to other strings.
-#
-# So we do this with a subclass that's both a generator *and*
-# a command action.  The overridden methods all do a quick check
-# of the construction variable, and if it's a string we just call
-# the corresponding CommandAction method to do the heavy lifting.
-# If not, then we call the same-named CommandGeneratorAction method.
-# The CommandGeneratorAction methods work by using the overridden
-# _generate() method, that is, our own way of handling "generation" of
-# an action based on what's in the construction variable.

-"""SCons.Builder
-
-Builder object subsystem.
-
-A Builder object is a callable that encapsulates information about how
-to execute actions to create a target Node (file) from source Nodes
-(files), and how to create those dependencies for tracking.
-
-The main entry point here is the Builder() factory method.  This provides
-a procedural interface that creates the right underlying Builder object
-based on the keyword arguments supplied and the types of the arguments.
-
-The goal is for this external interface to be simple enough that the
-vast majority of users can create new Builders as necessary to support
-building new types of files in their configurations, without having to
-dive any deeper into this subsystem.
-
-The base class here is BuilderBase.  This is a concrete base class which
-does, in fact, represent the Builder objects that we (or users) create.
-
-There is also a proxy that looks like a Builder:
-
-    CompositeBuilder
-
-        This proxies for a Builder with an action that is actually a
-        dictionary that knows how to map file suffixes to a specific
-        action.  This is so that we can invoke different actions
-        (compilers, compile options) for different flavors of source
-        files.
-
-Builders and their proxies have the following public interface methods
-used by other modules:
-
-    __call__()
-        THE public interface.  Calling a Builder object (with the
-        use of internal helper methods) sets up the target and source
-        dependencies, appropriate mapping to a specific action, and the
-        environment manipulation necessary for overridden construction
-        variable.  This also takes care of warning about possible mistakes
-        in keyword arguments.
-
-    add_emitter()
-        Adds an emitter for a specific file suffix, used by some Tool
-        modules to specify that (for example) a yacc invocation on a .y
-        can create a .h *and* a .c file.
-
-    add_action()
-        Adds an action for a specific file suffix, heavily used by
-        Tool modules to add their specific action(s) for turning
-        a source file into an object file to the global static
-        and shared object file Builders.
-
-There are the following methods for internal use within this module:
-
-    _execute()
-        The internal method that handles the heavily lifting when a
-        Builder is called.  This is used so that the __call__() methods
-        can set up warning about possible mistakes in keyword-argument
-        overrides, and *then* execute all of the steps necessary so that
-        the warnings only occur once.
-
-    get_name()
-        Returns the Builder's name within a specific Environment,
-        primarily used to try to return helpful information in error
-        messages.
-
-    adjust_suffix()
-    get_prefix()
-    get_suffix()
-    get_src_suffix()
-    set_src_suffix()
-        Miscellaneous stuff for handling the prefix and suffix
-        manipulation we use in turning source file names into target
-        file names.

-# The purpose of this module is to define how a check is to be performed.
-# Use one of the Check...() functions below.
-#
-
-#
-# A context class is used that defines functions for carrying out the tests,
-# logging and messages.  The following methods and members must be present:
-#
-# context.Display(msg)  Function called to print messages that are normally
-#                       displayed for the user.  Newlines are explicitly used.
-#                       The text should also be written to the logfile!
-#
-# context.Log(msg)      Function called to write to a log file.
-#
-# context.BuildProg(text, ext)
-#                       Function called to build a program, using "ext" for the
-#                       file extention.  Must return an empty string for
-#                       success, an error message for failure.
-#                       For reliable test results building should be done just
-#                       like an actual program would be build, using the same
-#                       command and arguments (including configure results so
-#                       far).
-#
-# context.CompileProg(text, ext)
-#                       Function called to compile a program, using "ext" for
-#                       the file extention.  Must return an empty string for
-#                       success, an error message for failure.
-#                       For reliable test results compiling should be done just
-#                       like an actual source file would be compiled, using the
-#                       same command and arguments (including configure results
-#                       so far).
-#
-# context.AppendLIBS(lib_name_list)
-#                       Append "lib_name_list" to the value of LIBS.
-#                       "lib_namelist" is a list of strings.
-#                       Return the value of LIBS before changing it (any type
-#                       can be used, it is passed to SetLIBS() later.)
-#
-# context.PrependLIBS(lib_name_list)
-#                       Prepend "lib_name_list" to the value of LIBS.
-#                       "lib_namelist" is a list of strings.
-#                       Return the value of LIBS before changing it (any type
-#                       can be used, it is passed to SetLIBS() later.)
-#
-# context.SetLIBS(value)
-#                       Set LIBS to "value".  The type of "value" is what
-#                       AppendLIBS() returned.
-#                       Return the value of LIBS before changing it (any type
-#                       can be used, it is passed to SetLIBS() later.)
-#
-# context.headerfilename
-#                       Name of file to append configure results to, usually
-#                       "confdefs.h".
-#                       The file must not exist or be empty when starting.
-#                       Empty or None to skip this (some tests will not work!).
-#
-# context.config_h      (may be missing). If present, must be a string, which
-#                       will be filled with the contents of a config_h file.
-#
-# context.vardict       Dictionary holding variables used for the tests and
-#                       stores results from the tests, used for the build
-#                       commands.
-#                       Normally contains "CC", "LIBS", "CPPFLAGS", etc.
-#
-# context.havedict      Dictionary holding results from the tests that are to
-#                       be used inside a program.
-#                       Names often start with "HAVE_".  These are zero
-#                       (feature not present) or one (feature present).  Other
-#                       variables may have any value, e.g., "PERLVERSION" can
-#                       be a number and "SYSTEMNAME" a string.

-                 non-zero returned code.

-                     Must be nonzero unless due to an explicit Exit()

-__doc__ = """Memoizer
-
-A decorator-based implementation to count hits and misses of the computed
-values that various methods cache in memory.
-
-Use of this modules assumes that wrapped methods be coded to cache their
-values in a consistent way. In particular, it requires that the class uses a
-dictionary named "_memo" to store the cached values.
-
-Here is an example of wrapping a method that returns a computed value,
-with no input parameters:
-
-    @SCons.Memoize.CountMethodCall
-    def foo(self):
-
-        try:                                                    # Memoization
-            return self._memo['foo']                            # Memoization
-        except KeyError:                                        # Memoization
-            pass                                                # Memoization
-
-        result = self.compute_foo_value()
-
-        self._memo['foo'] = result                              # Memoization
-
-        return result
-
-Here is an example of wrapping a method that will return different values
-based on one or more input arguments:
-
-    def _bar_key(self, argument):                               # Memoization
-        return argument                                         # Memoization
-
-    @SCons.Memoize.CountDictCall(_bar_key)
-    def bar(self, argument):
-
-        memo_key = argument                                     # Memoization
-        try:                                                    # Memoization
-            memo_dict = self._memo['bar']                       # Memoization
-        except KeyError:                                        # Memoization

-            self._memo['dict'] = memo_dict                      # Memoization
-        else:                                                   # Memoization
-            try:                                                # Memoization
-                return memo_dict[memo_key]                      # Memoization
-            except KeyError:                                    # Memoization

-
-        memo_dict[memo_key] = result                            # Memoization
-
-        return result
-
-Deciding what to cache is tricky, because different configurations
-can have radically different performance tradeoffs, and because the
-tradeoffs involved are often so non-obvious.  Consequently, deciding
-whether or not to cache a given method will likely be more of an art than
-a science, but should still be based on available data from this module.
-Here are some VERY GENERAL guidelines about deciding whether or not to
-cache return values from a method that's being called a lot:
-
-    --  The first question to ask is, "Can we change the calling code
-        so this method isn't called so often?"  Sometimes this can be
-        done by changing the algorithm.  Sometimes the *caller* should
-        be memoized, not the method you're looking at.
-
-    --  The memoized function should be timed with multiple configurations
-        to make sure it doesn't inadvertently slow down some other
-        configuration.
-
-    --  When memoizing values based on a dictionary key composed of
-        input arguments, you don't need to use all of the arguments
-        if some of them don't affect the return values.

-        # was configured.  We don't know from just looking at it whether
-        # it was a build signature, a content signature, or a timestamp
-        # "signature".  Since we no longer use build signatures, the
-        # best we can do is look at the length and if it's thirty two,
-        # assume that it was (or might have been) a content signature.
-        # If it was actually a build signature, then it will cause a
-        # rebuild anyway when it doesn't match the new content signature,

-"""SCons.Node
-
-The Node package for the SCons software construction utility.
-
-This is, in many ways, the heart of SCons.
-
-A Node is where we encapsulate all of the dependency information about
-any thing that SCons can build, or about any thing which SCons can use
-to build some other thing.  The canonical "thing," of course, is a file,
-but a Node can also represent something remote (like a web page) or
-something completely abstract (like an Alias).
-
-Each specific type of "thing" is specifically represented by a subclass
-of the Node base class:  Node.FS.File for files, Node.Alias for aliases,
-etc.  Dependency information is kept here in the base class, and
-information specific to files/aliases/etc. is in the subclass.  The
-goal, if we've done this correctly, is that any type of "thing" should
-be able to depend on any other type of "thing."

-"""SCons.Platform

-SCons platform selection.
-
-This looks for modules that define a callable object that can modify a
-construction environment as appropriate for a given platform.
-
-Note that we take a more simplistic view of "platform" than Python does.
-We're looking for a single string that determines a set of
-tool-independent variables with which to initialize a construction
-environment.  Consequently, we'll examine both sys.platform and os.name
-(and anything else that might come in to play) in order to return some
-specification which is unique enough for our purposes.
-
-Note that because this subsysem just *selects* a callable that can
-modify a construction environment, it's possible for people to define
-their own "platform specification" in an arbitrary callable function.
-No one needs to use or tie in to this subsystem in order to roll
-their own platform definition.

-"""SCons.SConf
-
-Autoconf-like configuration support.
-
-In other words, SConf allows to run tests on the build machine to detect
-capabilities of system and do some things based on result: generate config
-files, header files for C/C++, update variables in environment.
-
-Tests on the build system can detect if compiler sees header files, if
-libraries are installed, if some command line options are supported etc.

-#   USE module_name
-#   USE :: module_name
-#   USE, INTRINSIC :: module_name
-#   USE, NON_INTRINSIC :: module_name
-#
-#   Limitations
-#
-#   --  While the regex can handle multiple USE statements on one line,
-#       it cannot properly handle them if they are commented out.
-#       In either of the following cases:
-#
-#            !  USE mod_a ; USE mod_b         [entire line is commented out]

-#       the second module name (mod_b) will be picked up as a dependency

-#       treating the comment character as an end-of-line character
-#       in addition to the normal linefeed, loop over each line,
-#       weeding out the comments, and looking for the USE statements.
-#       One advantage to this is that the regex passed to the scanner
-#       would no longer need to match a semicolon.
-#
-#   --  I question whether or not we need to detect dependencies to
-#       INTRINSIC modules because these are built-in to the compiler.
-#       If we consider them a dependency, will SCons look for them, not
-#       find them, and kill the build?  Or will we there be standard
-#       compiler-specific directories we will need to point to so the
-#       compiler and SCons can locate the proper object and mod files?
-

-#   ^                  : start of line
-#   (?:                : group a collection of regex symbols without saving the match as a "group"
-#      ^|;             : matches either the start of the line or a semicolon - semicolon
-#   )                  : end the unsaved grouping
-#   \s*                : any amount of white space
-#   USE                : match the string USE, case insensitive
-#   (?:                : group a collection of regex symbols without saving the match as a "group"
-#      \s+|            : match one or more whitespace OR ....  (the next entire grouped set of regex symbols)

-#   The INCLUDE statement regex matches the following:
-#
-#   INCLUDE 'some_Text'
-#   INCLUDE "some_Text"
-#   INCLUDE "some_Text" ; INCLUDE "some_Text"
-#   INCLUDE kind_"some_Text"
-#   INCLUDE kind_'some_Text"
-#
-#   where some_Text can include any alphanumeric and/or special character
-#   as defined by the Fortran 2003 standard.
-#
-#   Limitations:
-#
-#   --  The Fortran standard dictates that a " or ' in the INCLUDE'd
-#       string must be represented as a "" or '', if the quotes that wrap
-#       the entire string are either a ' or ", respectively.   While the
-#       regular expression below can detect the ' or " characters just fine,
-#       the scanning logic, presently is unable to detect them and reduce
-#       them to a single instance.  This probably isn't an issue since,
-#       in practice, ' or " are not generally used in filenames.
-#
-#   --  This regex will not properly deal with multiple INCLUDE statements
-#       when the entire line has been commented out, ala
-#
-#           ! INCLUDE 'some_file' ; INCLUDE 'some_file'
-#
-#       In such cases, it will properly ignore the first INCLUDE file,
-#       but will actually still pick up the second.  Interestingly enough,
-#       the regex will properly deal with these cases:
-#
-#             INCLUDE 'some_file'
-#             INCLUDE 'some_file' !; INCLUDE 'some_file'
-#
-#       To get around the above limitation, the FORTRAN programmer could
-#       simply comment each INCLUDE statement separately, like this
-#
-#           ! INCLUDE 'some_file' !; INCLUDE 'some_file'
-#
-#       The way I see it, the only way to get around this limitation would
-#       be to modify the scanning logic to replace the calls to re.findall
-#       with a custom loop that processes each line separately, throwing
-#       away fully commented out lines before attempting to match against
-#       the INCLUDE syntax.
-#
-#   Here is a breakdown of the regex:
-#
-#   (?i)               : regex is case insensitive
-#   (?:                : begin a non-saving group that matches the following:
-#      ^               :    either the start of the line
-#      |               :                or
-#      ['">]\s*;       :    a semicolon that follows a single quote,
-#                           double quote or greater than symbol (with any
-#                           amount of whitespace in between).  This will
-#                           allow the regex to match multiple INCLUDE
-#                           statements per line (although it also requires
-#                           the positive lookahead assertion that is
-#                           used below).  It will even properly deal with
-#                           (i.e. ignore) cases in which the additional
-#                           INCLUDES are part of an in-line comment, ala
-#                                           "  INCLUDE 'someFile' ! ; INCLUDE 'someFile2' "
-#   )                  : end of non-saving group
-#   \s*                : any amount of white space
-#   INCLUDE            : match the string INCLUDE, case insensitive
-#   \s+                : match one or more white space characters
-#   (?\w+_)?           : match the optional "kind-param _" prefix allowed by the standard
-#   [<"']              : match the include delimiter - an apostrophe, double quote, or less than symbol
-#   (.+?)              : match one or more characters that make up
-#                        the included path and file name and save it
-#                        in a group.  The Fortran standard allows for
-#                        any non-control character to be used.  The dot
-#                        operator will pick up any character, including
-#                        control codes, but I can't conceive of anyone
-#                        putting control codes in their file names.
-#                        The question mark indicates it is non-greedy so
-#                        that regex will match only up to the next quote,
-#                        double quote, or greater than symbol
-#   (?=["'>])          : positive lookahead assertion to match the include
-#                        delimiter - an apostrophe, double quote, or
-#                        greater than symbol.  This level of complexity
-#                        is required so that the include delimiter is
-#                        not consumed by the match, thus allowing the
-#                        sub-regex discussed above to uniquely match a
-#                        set of semicolon-separated INCLUDE statements

-        'argument' - an optional argument that, if specified, will be
-        passed to both the scanner function and the path_function.
-
-        'skeys' - an optional list argument that can be used to determine
-        which scanner should be used for a given Node. In the case of File
-        nodes, for example, the 'skeys' would be file suffixes.
-
-        'path_function' - a function that takes four or five arguments
-        (a construction environment, Node for the directory containing
-        the SConscript file that defined the primary target, list of
-        target nodes, list of source nodes, and optional argument for
-        this instance) and returns a tuple of the directories that can
-        be searched for implicit dependency files.  May also return a
-        callable() which is called with no args and returns the tuple
-        (supporting Bindable class).
-
-        'node_class' - the class of Nodes which this scan will return.
-        If node_class is None, then this scanner will not enforce any
-        Node conversion and will return the raw results from the
-        underlying scanner function.
-
-        'node_factory' - the factory function to be called to translate
-        the raw results returned by the scanner function into the
-        expected node_class objects.
-
-        'scan_check' - a function to be called to first check whether
-        this node really needs to be scanned.
-
-        'recursive' - specifies that this scanner should be invoked
-        recursively on all of the implicit dependencies it returns
-        (the canonical example being #include lines in C source files).
-        May be a callable, which will be called to filter the list
-        of nodes found to select a subset for recursive scanning
-        (the canonical example being only recursively scanning
-        subdirectories within a directory).
-
-        The scanner function's first argument will be a Node that should
-        be scanned for dependencies, the second argument will be an
-        Environment object, the third argument will be the tuple of paths
-        returned by the path_function, and the fourth argument will be
-        the value passed into 'argument', and the returned list should
-        contain the Nodes for all the direct dependencies of the file.
-
-        Examples:
-
-        s = Scanner(my_scanner_function)
-
-        s = Scanner(function = my_scanner_function)

-        s = Scanner(function = my_scanner_function, argument = 'foo')

-# TODO:
-#
-# This has the potential to grow into something with a really big life
-# of its own, which might or might not be a good thing.  Nevertheless,
-# here are some enhancements that will probably be requested some day
-# and are worth keeping in mind (assuming this takes off):
-# 
-# - A command to re-read / re-load the SConscript files.  This may
-#   involve allowing people to specify command-line options (e.g. -f,
-#   -I, --no-site-dir) that affect how the SConscript files are read.
-#
-# - Additional command-line options on the "build" command.
-#
-#   Of the supported options that seemed to make sense (after a quick
-#   pass through the list), the ones that seemed likely enough to be
-#   used are listed in the man page and have explicit test scripts.
-#
-#   These had code changed in Script/Main.py to support them, but didn't
-#   seem likely to be used regularly, so had no test scripts added:
-#
-#       build --diskcheck=*
-#       build --implicit-cache=*
-#       build --implicit-deps-changed=*
-#       build --implicit-deps-unchanged=*
-#
-#   These look like they should "just work" with no changes to the
-#   existing code, but like those above, look unlikely to be used and
-#   therefore had no test scripts added:
-#
-#       build --random
-#
-#   These I'm not sure about.  They might be useful for individual
-#   "build" commands, and may even work, but they seem unlikely enough
-#   that we'll wait until they're requested before spending any time on
-#   writing test scripts for them, or investigating whether they work.
-#
-#       build -q [???  is there a useful analog to the exit status?]
-#       build --duplicate=
-#       build --profile=
-#       build --max-drift=
-#       build --warn=*
-#       build --Y
-#
-# - Most of the SCons command-line options that the "build" command
-#   supports should be settable as default options that apply to all
-#   subsequent "build" commands.  Maybe a "set {option}" command that
-#   maps to "SetOption('{option}')".
-#
-# - Need something in the 'help' command that prints the -h output.
-#
-# - A command to run the configure subsystem separately (must see how
-#   this interacts with the new automake model).
-#
-# - Command-line completion of target names; maybe even of SCons options?
-#   Completion is something that's supported by the Python cmd module,
-#   so this should be doable without too much trouble.

-    """
-    Holder class for uniform access to SCons options, regardless
-    of whether or not they can be set on the command line or in the
-    SConscript files (using the SetOption() function).
-
-    A SCons option value can originate three different ways:
-
-        1)  set on the command line;
-        2)  set in an SConscript file;
-        3)  the default setting (from the the op.add_option()
-            calls in the Parser() function, below).
-
-    The command line always overrides a value set in a SConscript file,
-    which in turn always overrides default settings.  Because we want
-    to support user-specified options in the SConscript file itself,
-    though, we may not know about all of the options when the command
-    line is first parsed, so we can't make all the necessary precedence
-    decisions at the time the option is configured.
-
-    The solution implemented in this class is to keep these different sets
-    of settings separate (command line, SConscript file, and default)
-    and to override the __getattr__() method to check them in turn.
-    This should allow the rest of the code to just fetch values as
-    attributes of an instance of this class, without having to worry
-    about where they came from.
-
-    Note that not all command line options are settable from SConscript
-    files, and the ones that are must be explicitly added to the
-    "settable" list in this class, and optionally validated and coerced
-    in the set_option() method.

-Generic Taskmaster module for the SCons build engine.
-
-This module contains the primary interface(s) between a wrapping user
-interface and the SCons build engine.  There are two key classes here:
-
-    Taskmaster
-        This is the main engine for walking the dependency graph and
-        calling things to decide what does or doesn't need to be built.
-
-    Task
-        This is the base class for allowing a wrapping interface to
-        decide what does or doesn't actually need to be done.  The
-        intention is for a wrapping interface to subclass this as
-        appropriate for different types of behavior it may need.
-
-        The canonical example is the SCons native Python interface,
-        which has Task subclasses that handle its specific behavior,
-        like printing "`foo' is up to date" when a top-level target
-        doesn't need to be built, and handling the -c option by removing
-        targets as its "build" action.  There is also a separate subclass
-        for suppressing this output when the -q option is used.
-
-        The Taskmaster instantiates a Task object for each (set of)
-        target(s) that it decides need to be evaluated and/or built.

-
-        This function is used strictly for debugging the taskmaster by
-        checking that no invariants are violated. It is not used in
-        normal operation.
-
-        The pending_children set is used to detect cycles in the
-        dependency graph. We call a "pending child" a child that is
-        found in the "pending" state when checking the dependencies of
-        its parent node.
-
-        A pending child can occur when the Taskmaster completes a loop
-        through a cycle. For example, lets imagine a graph made of
-        three node (A, B and C) making a cycle. The evaluation starts
-        at node A. The taskmaster first consider whether node A's
-        child B is up-to-date. Then, recursively, node B needs to
-        check whether node C is up-to-date. This leaves us with a
-        dependency graph looking like:
-
-                                      Next candidate \
-                                                      \
-        Node A (Pending) --> Node B(Pending) --> Node C (NoState)
-                ^                                     |
-                |                                     |
-                +-------------------------------------+
-
-        Now, when the Taskmaster examines the Node C's child Node A,
-        it finds that Node A is in the "pending" state. Therefore,
-        Node A is a pending child of node C.
-
-        Pending children indicate that the Taskmaster has potentially
-        loop back through a cycle. We say potentially because it could
-        also occur when a DAG is evaluated in parallel. For example,
-        consider the following graph:
-
-
-        Node A (Pending) --> Node B(Pending) --> Node C (Pending) --> ...
-                |                                     ^
-                |                                     |
-                +----------> Node D (NoState) --------+
-                                  /
-                  Next candidate /
-
-        The Taskmaster first evaluates the nodes A, B, and C and
-        starts building some children of node C. Assuming, that the
-        maximum parallel level has not been reached, the Taskmaster
-        will examine Node D. It will find that Node C is a pending
-        child of Node D.
-
-        In summary, evaluating a graph with a cycle will always
-        involve a pending child at one point. A pending child might
-        indicate either a cycle or a diamond-shaped DAG. Only a
-        fraction of the nodes ends-up being a "pending child" of
-        another node. This keeps the pending_children set small in
-        practice.
-
-        We can differentiate between the two cases if we wait until
-        the end of the build. At this point, all the pending children
-        nodes due to a diamond-shaped DAG will have been properly
-        built (or will have failed to build). But, the pending
-        children involved in a cycle will still be in the pending
-        state.
-
-        The taskmaster removes nodes from the pending_children set as
-        soon as a pending_children node moves out of the pending
-        state. This also helps to keep the pending_children set small.

-
-  It seems like `SCons.Node.FS.Base.get_path()` returns absolute paths
-  for nodes that are outside of current working directory (`env.fs.getcwd()`).
-  Here, we often have `SConscript`, `POT` and `PO` files within `po/`
-  directory and source files (e.g. `*.c`) outside of it. When generating `POT`
-  template file, references to source files are written to `POT` template, so
-  a translator may later quickly jump to appropriate source file and line from
-  its `PO` editor (e.g. `poedit`).  Relative paths in  `PO` file are usually
-  interpreted by `PO` editor as paths relative to the place, where `PO` file
-  lives. The absolute paths would make resultant `POT` file nonportable, as
-  the references would be correct only on the machine, where `POT` file was
-  recently re-created. For such reason, we need a function, which always
-  returns relative paths. This is the purpose of `RPaths` callable object.
-
-  The `__call__` method returns paths relative to current woking directory, but
-  we assume, that *xgettext(1)* is run from the directory, where target file is
-  going to be created.

-"""SCons.Tool.dmd
-
-Tool-specific initialization for the Digital Mars D compiler.
-(http://digitalmars.com/d)
-
-Originally coded by Andy Friesen (andy@ikagames.com)
-15 November 2003
-
-Evolved by Russel Winder (russel@winder.org.uk)
-2010-02-07 onwards
-
-There are a number of problems with this script at this point in time.
-The one that irritates the most is the Windows linker setup.  The D
-linker doesn't have a way to add lib paths on the commandline, as far
-as I can see.  You have to specify paths relative to the SConscript or
-use absolute paths.  To hack around it, add '#/blah'.  This will link
-blah.lib from the directory where SConstruct resides.
-
-Compiler variables:
-    DC - The name of the D compiler to use.  Defaults to dmd or gdmd,
-        whichever is found.
-    DPATH - List of paths to search for import modules.
-    DVERSIONS - List of version tags to enable when compiling.
-    DDEBUG - List of debug tags to enable when compiling.
-
-Linker related variables:
-    LIBS - List of library files to link in.
-    DLINK - Name of the linker to use.  Defaults to dmd or gdmd,
-        whichever is found.
-    DLINKFLAGS - List of linker flags.
-
-Lib tool variables:
-    DLIB - Name of the lib tool to use.  Defaults to lib.
-    DLIBFLAGS - List of flags to pass to the lib tool.
-    LIBS - Same as for the linker. (libraries to pull into the .lib)

-RPM specific helper routines for general usage in the test framework
-and SCons core modules.
-
-Since we check for the RPM package target name in several places,
-we have to know which machine/system name RPM will use for the current
-hardware setup. The following dictionaries and functions try to
-mimic the exact naming rules of the RPM source code.
-They were directly derived from the file "rpmrc.in" of the version
-rpm-4.9.1.3. For updating to a more recent version of RPM, this Python
-script can be used standalone. The usage() function below shows the
-exact syntax.

-Textfile/Substfile builder for SCons.
-
-    Create file 'target' which typically is a textfile.  The 'source'
-    may be any combination of strings, Nodes, or lists of same.  A
-    'linesep' will be put between any part written and defaults to
-    os.linesep.
-
-    The only difference between the Textfile builder and the Substfile
-    builder is that strings are converted to Value() nodes for the
-    former and File() nodes for the latter.  To insert files in the
-    former or strings in the latter, wrap them in a File() or Value(),
-    respectively.
-
-    The values of SUBST_DICT first have any construction variables
-    expanded (its keys are not expanded).  If a value of SUBST_DICT is
-    a python callable function, it is called and the result is expanded
-    as the value.  Values are substituted in a "random" order; if any
-    substitution could be further expanded by another subsitition, it
-    is unpredictible whether the expansion will occur.

-# The original idea for AddMethod() and RenameFunction() come from the
-# following post to the ActiveState Python Cookbook:
-#
-#	ASPN: Python Cookbook : Install bound methods in an instance
-#	http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/223613
-#
-# That code was a little fragile, though, so the following changes
-# have been wrung on it:
-#
-# * Switched the installmethod() "object" and "function" arguments,
-#   so the order reflects that the left-hand side is the thing being
-#   "assigned to" and the right-hand side is the value being assigned.
-#
-# * Changed explicit type-checking to the "try: klass = object.__class__"
-#   block in installmethod() below so that it still works with the
-#   old-style classes that SCons uses.
-#
-# * Replaced the by-hand creation of methods and functions with use of
-#   the "new" module, as alluded to in Alex Martelli's response to the
-#   following Cookbook post:
-#
-#	ASPN: Python Cookbook : Dynamically added methods to a class

-"""SCons.Variables.PathVariable
-
-This file defines an option type for SCons implementing path settings.
-
-To be used whenever a a user-specified path override should be allowed.
-
-Arguments to PathVariable are:
-  option-name  = name of this option on the command line (e.g. "prefix")
-  option-help  = help string for option
-  option-dflt  = default value for this option
-  validator    = [optional] validator for option value.  Predefined
-                 validators are:
-
-                     PathAccept -- accepts any path setting; no validation
-                     PathIsDir  -- path must be an existing directory
-                     PathIsDirCreate -- path must be a dir; will create
-                     PathIsFile -- path must be a file
-                     PathExists -- path must exist (any type) [default]
-
-                 The validator is a function that is called and which
-                 should return True or False to indicate if the path
-                 is valid.  The arguments to the validator function
-                 are: (key, val, env).  The key is the name of the
-                 option, the val is the path specified for the option,
-                 and the env is the env to which the Otions have been
-                 added.
-
-Usage example:
-
-  Examples:
-      prefix=/usr/local
-
-  opts = Variables()
-
-  opts = Variables()
-  opts.Add(PathVariable('qtdir',
-                      'where the root of Qt is installed',
-                      qtdir, PathIsDir))
-  opts.Add(PathVariable('qt_includes',
-                      'where the Qt includes are installed',
-                      '$qtdir/includes', PathIsDirCreate))
-  opts.Add(PathVariable('qt_libraries',
-                      'where the Qt library is installed',
-                      '$qtdir/lib'))

-SCons compatibility package for old Python versions
-
-This subpackage holds modules that provide backwards-compatible
-implementations of various things that we'd like to use in SCons but which
-only show up in later versions of Python than the early, old version(s)
-we still support.
-
-Other code will not generally reference things in this package through
-the SCons.compat namespace.  The modules included here add things to
-the builtins namespace or the global module list so that the rest
-of our code can use the objects and names imported here regardless of
-Python version.
-
-Simply enough, things that go in the builtins name space come from
-our _scons_builtins module.
-
-The rest of the things here will be in individual compatibility modules
-that are either: 1) suitably modified copies of the future modules that
-we want to use; or 2) backwards compatible re-implementations of the
-specific portions of a future module's API that we want to use.
-
-GENERAL WARNINGS:  Implementations of functions in the SCons.compat
-modules are *NOT* guaranteed to be fully compliant with these functions in
-later versions of Python.  We are only concerned with adding functionality
-that we actually use in SCons, so be wary if you lift this code for
-other uses.  (That said, making these more nearly the same as later,
-official versions is still a desirable goal, we just don't need to be
-obsessive about it.)
-
-We name the compatibility modules with an initial '_scons_' (for example,
-_scons_subprocess.py is our compatibility module for subprocess) so
-that we can still try to import the real module name and fall back to
-our compatibility module if we get an ImportError.  The import_as()
-function defined below loads the module as the "real" name (without the
-'_scons'), after which all of the "import {module}" statements in the
-rest of our code will find our pre-loaded compatibility module.

-Compatibility idioms for builtins names
-
-This module adds names to the builtins module for things that we want
-to use in SCons but which don't show up until later Python versions than
-the earliest ones we support.
-
-This module checks for the following builtins names:
-
-        all()
-        any()
-        memoryview()
-
-Implementations of functions are *NOT* guaranteed to be fully compliant
-with these functions in later versions of Python.  We are only concerned
-with adding functionality that we actually use in SCons, so be wary
-if you lift this code for other uses.  (That said, making these more
-nearly the same as later, official versions is still a desirable goal,
-we just don't need to be obsessive about it.)
-
-If you're looking at this with pydoc and various names don't show up in
-the FUNCTIONS or DATA output, that means those names are already built in
-to this version of Python and we don't need to add them from this module.

-"""Classes to represent arbitrary sets (including sets of sets).
-
-This module implements sets using dictionaries whose values are
-ignored.  The usual operations (union, intersection, deletion, etc.)
-are provided as both methods and operators.
-
-Important: sets are not sequences!  While they support 'x in s',
-'len(s)', and 'for x in s', none of those operations are unique for
-sequences; for example, mappings support all three as well.  The
-characteristic operation for sequences is subscripting with small
-integers: s[i], for i in range(len(s)).  Sets don't support
-subscripting at all.  Also, sequences allow multiple occurrences and
-their elements have a definite order; sets on the other hand don't
-record multiple occurrences and don't remember the order of element
-insertion (which is why they don't support s[i]).
-
-The following classes are provided:
-
-BaseSet -- All the operations common to both mutable and immutable
-    sets. This is an abstract class, not meant to be directly
-    instantiated.
-
-Set -- Mutable sets, subclass of BaseSet; not hashable.
-
-ImmutableSet -- Immutable sets, subclass of BaseSet; hashable.
-    An iterable argument is mandatory to create an ImmutableSet.
-
-_TemporarilyImmutableSet -- A wrapper around a Set, hashable,
-    giving the same hash value as the immutable set equivalent
-    would have.  Do not use this class directly.
-
-Only hashable objects can be added to a Set. In particular, you cannot
-really add a Set as an element to another Set; if you try, what is
-actually added is an ImmutableSet built from it (it compares equal to
-the one you tried adding).
-
-When you ask if `x in y' where x is a Set and y is a Set or
-ImmutableSet, x is wrapped into a _TemporarilyImmutableSet z, and
-what's tested is actually `z in y'.

-r"""subprocess - Subprocesses with accessible I/O streams
-
-This module allows you to spawn processes, connect to their
-input/output/error pipes, and obtain their return codes.  This module
-intends to replace several other, older modules and functions, like:
-
-os.system
-os.spawn*
-os.popen*
-popen2.*
-commands.*
-
-Information about how the subprocess module can be used to replace these
-modules and functions can be found below.
-
-
-
-Using the subprocess module
-===========================
-This module defines one class called Popen:
-
-class Popen(args, bufsize=0, executable=None,
-            stdin=None, stdout=None, stderr=None,
-            preexec_fn=None, close_fds=False, shell=False,
-            cwd=None, env=None, universal_newlines=False,
-            startupinfo=None, creationflags=0):
-
-
-Arguments are:
-
-args should be a string, or a sequence of program arguments.  The
-program to execute is normally the first item in the args sequence or
-string, but can be explicitly set by using the executable argument.
-
-On UNIX, with shell=False (default): In this case, the Popen class
-uses os.execvp() to execute the child program.  args should normally
-be a sequence.  A string will be treated as a sequence with the string
-as the only item (the program to execute).
-
-On UNIX, with shell=True: If args is a string, it specifies the
-command string to execute through the shell.  If args is a sequence,
-the first item specifies the command string, and any additional items
-will be treated as additional shell arguments.
-
-On Windows: the Popen class uses CreateProcess() to execute the child
-program, which operates on strings.  If args is a sequence, it will be
-converted to a string using the list2cmdline method.  Please note that
-not all MS Windows applications interpret the command line the same
-way: The list2cmdline is designed for applications using the same
-rules as the MS C runtime.
-
-bufsize, if given, has the same meaning as the corresponding argument
-to the built-in open() function: 0 means unbuffered, 1 means line
-buffered, any other positive value means use a buffer of
-(approximately) that size.  A negative bufsize means to use the system
-default, which usually means fully buffered.  The default value for
-bufsize is 0 (unbuffered).
-
-stdin, stdout and stderr specify the executed programs' standard
-input, standard output and standard error file handles, respectively.
-Valid values are PIPE, an existing file descriptor (a positive
-integer), an existing file object, and None.  PIPE indicates that a
-new pipe to the child should be created.  With None, no redirection
-will occur; the child's file handles will be inherited from the
-parent.  Additionally, stderr can be STDOUT, which indicates that the
-stderr data from the applications should be captured into the same
-file handle as for stdout.
-
-If preexec_fn is set to a callable object, this object will be called
-in the child process just before the child is executed.
-
-If close_fds is true, all file descriptors except 0, 1 and 2 will be
-closed before the child process is executed.
-
-if shell is true, the specified command will be executed through the
-shell.
-
-If cwd is not None, the current directory will be changed to cwd
-before the child is executed.
-
-If env is not None, it defines the environment variables for the new
-process.
-
-If universal_newlines is true, the file objects stdout and stderr are
-opened as a text files, but lines may be terminated by any of '\n',
-the Unix end-of-line convention, '\r', the Macintosh convention or
-'\r\n', the Windows convention.  All of these external representations
-are seen as '\n' by the Python program.  Note: This feature is only
-available if Python is built with universal newline support (the
-default).  Also, the newlines attribute of the file objects stdout,
-stdin and stderr are not updated by the communicate() method.
-
-The startupinfo and creationflags, if given, will be passed to the
-underlying CreateProcess() function.  They can specify things such as
-appearance of the main window and priority for the new process.
-(Windows only)
-
-
-This module also defines two shortcut functions:
-
-call(*popenargs, **kwargs):
-    Run command with arguments.  Wait for command to complete, then
-    return the returncode attribute.
-
-    The arguments are the same as for the Popen constructor.  Example:
-
-    retcode = call(["ls", "-l"])
-
-check_call(*popenargs, **kwargs):
-    Run command with arguments.  Wait for command to complete.  If the
-    exit code was zero then return, otherwise raise
-    CalledProcessError.  The CalledProcessError object will have the
-    return code in the returncode attribute.
-
-    The arguments are the same as for the Popen constructor.  Example:
-
-    check_call(["ls", "-l"])
-
-Exceptions
-----------
-Exceptions raised in the child process, before the new program has
-started to execute, will be re-raised in the parent.  Additionally,
-the exception object will have one extra attribute called
-'child_traceback', which is a string containing traceback information
-from the childs point of view.
-
-The most common exception raised is OSError.  This occurs, for
-example, when trying to execute a non-existent file.  Applications
-should prepare for OSErrors.
-
-A ValueError will be raised if Popen is called with invalid arguments.
-
-check_call() will raise CalledProcessError, if the called process
-returns a non-zero return code.
-
-
-Security
---------
-Unlike some other popen functions, this implementation will never call
-/bin/sh implicitly.  This means that all characters, including shell
-metacharacters, can safely be passed to child processes.
-
-
-Popen objects
-=============
-Instances of the Popen class have the following methods:
-
-poll()
-    Check if child process has terminated.  Returns returncode
-    attribute.
-
-wait()
-    Wait for child process to terminate.  Returns returncode attribute.
-
-communicate(input=None)
-    Interact with process: Send data to stdin.  Read data from stdout
-    and stderr, until end-of-file is reached.  Wait for process to
-    terminate.  The optional stdin argument should be a string to be
-    sent to the child process, or None, if no data should be sent to
-    the child.
-
-    communicate() returns a tuple (stdout, stderr).
-
-    Note: The data read is buffered in memory, so do not use this
-    method if the data size is large or unlimited.
-
-The following attributes are also available:
-
-stdin
-    If the stdin argument is PIPE, this attribute is a file object
-    that provides input to the child process.  Otherwise, it is None.
-
-stdout
-    If the stdout argument is PIPE, this attribute is a file object
-    that provides output from the child process.  Otherwise, it is
-    None.
-
-stderr
-    If the stderr argument is PIPE, this attribute is file object that
-    provides error output from the child process.  Otherwise, it is
-    None.
-
-pid
-    The process ID of the child process.
-
-returncode
-    The child return code.  A None value indicates that the process
-    hasn't terminated yet.  A negative value -N indicates that the
-    child was terminated by signal N (UNIX only).
-
-
-Replacing older functions with the subprocess module
-====================================================
-In this section, "a ==> b" means that b can be used as a replacement
-for a.
-
-Note: All functions in this section fail (more or less) silently if
-the executed program cannot be found; this module raises an OSError
-exception.
-
-In the following examples, we assume that the subprocess module is
-imported with "from subprocess import *".
-
-
-Replacing /bin/sh shell backquote
----------------------------------
-output=`mycmd myarg`
-==>
-output = Popen(["mycmd", "myarg"], stdout=PIPE).communicate()[0]
-
-
-Replacing shell pipe line
--------------------------
-output=`dmesg | grep hda`
-==>
-p1 = Popen(["dmesg"], stdout=PIPE)
-p2 = Popen(["grep", "hda"], stdin=p1.stdout, stdout=PIPE)
-output = p2.communicate()[0]
-
-
-Replacing os.system()
----------------------
-sts = os.system("mycmd" + " myarg")
-==>
-p = Popen("mycmd" + " myarg", shell=True)
-pid, sts = os.waitpid(p.pid, 0)
-
-Note:
-
-* Calling the program through the shell is usually not required.
-
-* It's easier to look at the returncode attribute than the
-  exitstatus.
-
-A more real-world example would look like this:
-
-try:
-    retcode = call("mycmd" + " myarg", shell=True)
-    if retcode < 0:
-        print >>sys.stderr, "Child was terminated by signal", -retcode
-    else:
-        print >>sys.stderr, "Child returned", retcode
-except OSError, e:
-    print >>sys.stderr, "Execution failed:", e
-

-Replacing os.spawn*
--------------------
-P_NOWAIT example:
-
-pid = os.spawnlp(os.P_NOWAIT, "/bin/mycmd", "mycmd", "myarg")
-==>
-pid = Popen(["/bin/mycmd", "myarg"]).pid
-
-
-P_WAIT example:
-
-retcode = os.spawnlp(os.P_WAIT, "/bin/mycmd", "mycmd", "myarg")
-==>
-retcode = call(["/bin/mycmd", "myarg"])
-
-
-Vector example:
-
-os.spawnvp(os.P_NOWAIT, path, args)
-==>
-Popen([path] + args[1:])
-
-
-Environment example:
-
-os.spawnlpe(os.P_NOWAIT, "/bin/mycmd", "mycmd", "myarg", env)
-==>
-Popen(["/bin/mycmd", "myarg"], env={"PATH": "/usr/bin"})
-
-
-Replacing os.popen*
--------------------
-pipe = os.popen(cmd, mode='r', bufsize)
-==>
-pipe = Popen(cmd, shell=True, bufsize=bufsize, stdout=PIPE).stdout
-
-pipe = os.popen(cmd, mode='w', bufsize)
-==>
-pipe = Popen(cmd, shell=True, bufsize=bufsize, stdin=PIPE).stdin
-
-
-(child_stdin, child_stdout) = os.popen2(cmd, mode, bufsize)
-==>
-p = Popen(cmd, shell=True, bufsize=bufsize,
-          stdin=PIPE, stdout=PIPE, close_fds=True)
-(child_stdin, child_stdout) = (p.stdin, p.stdout)
-
-
-(child_stdin,
- child_stdout,
- child_stderr) = os.popen3(cmd, mode, bufsize)
-==>
-p = Popen(cmd, shell=True, bufsize=bufsize,
-          stdin=PIPE, stdout=PIPE, stderr=PIPE, close_fds=True)
-(child_stdin,
- child_stdout,
- child_stderr) = (p.stdin, p.stdout, p.stderr)
-
-
-(child_stdin, child_stdout_and_stderr) = os.popen4(cmd, mode, bufsize)
-==>
-p = Popen(cmd, shell=True, bufsize=bufsize,
-          stdin=PIPE, stdout=PIPE, stderr=STDOUT, close_fds=True)
-(child_stdin, child_stdout_and_stderr) = (p.stdin, p.stdout)
-
-
-Replacing popen2.*
-------------------
-Note: If the cmd argument to popen2 functions is a string, the command
-is executed through /bin/sh.  If it is a list, the command is directly
-executed.
-
-(child_stdout, child_stdin) = popen2.popen2("somestring", bufsize, mode)
-==>
-p = Popen(["somestring"], shell=True, bufsize=bufsize
-          stdin=PIPE, stdout=PIPE, close_fds=True)
-(child_stdout, child_stdin) = (p.stdout, p.stdin)
-
-
-(child_stdout, child_stdin) = popen2.popen2(["mycmd", "myarg"], bufsize, mode)
-==>
-p = Popen(["mycmd", "myarg"], bufsize=bufsize,
-          stdin=PIPE, stdout=PIPE, close_fds=True)
-(child_stdout, child_stdin) = (p.stdout, p.stdin)
-
-The popen2.Popen3 and popen3.Popen4 basically works as subprocess.Popen,
-except that:
-
-* subprocess.Popen raises an exception if the execution fails
-* the capturestderr argument is replaced with the stderr argument.
-* stdin=PIPE and stdout=PIPE must be specified.
-* popen2 closes all filedescriptors by default, but you have to specify
-  close_fds=True with subprocess.Popen.
