+
+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.

+
+        Note that there's a special trick here with the execute flag

+        if the user requested a no_exec (-n) build, then

+        is called, it does its showing but then just returns zero
+        instead of actually calling the action execution operation.
+        The problem for caching is that if the file does NOT exist in
+        cache then the CacheRetrieveString won't return anything to
+        show for the task, but the Action.__call__ won't call
+        CacheRetrieveFunc; instead it just returns zero, which makes
+        the code below think that the file *was* successfully
+        retrieved from the cache, therefore it doesn't do any
+        subsequent building.  However, the CacheRetrieveString didn't
+        print anything because it didn't actually exist in the cache,
+        and no more build actions will be performed, so the user just
+        sees nothing.  The fix is to tell Action.__call__ to always

+
+A metaclass 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.  Here is an example of wrapping a method
+that returns a computed value, with no input parameters:
+
+    memoizer_counters = []                                      # Memoization
+
+    memoizer_counters.append(SCons.Memoize.CountValue('foo'))   # Memoization
+
+    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
+
+    memoizer_counters.append(SCons.Memoize.CountDict('bar', _bar_key)) # Memoization
+
+    def bar(self, argument):
+
+        memo_key = argument                                     # Memoization
+        try:                                                    # Memoization
+            memo_dict = self._memo['bar']                       # Memoization
+        except KeyError:                                        # Memoization
+            memo_dict = {}                                      # Memoization
+            self._memo['dict'] = memo_dict                      # Memoization
+        else:                                                   # Memoization
+            try:                                                # Memoization
+                return memo_dict[memo_key]                      # Memoization
+            except KeyError:                                    # Memoization

+
+        result = self.compute_bar_value(argument)
+
+        memo_dict[memo_key] = result                            # Memoization
+
+        return result
+
+At one point we avoided replicating this sort of logic in all the methods
+by putting it right into this module, but we've moved away from that at
+present (see the "Historical Note," below.).
+
+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.
+
+Historical Note:  The initial Memoizer implementation actually handled
+the caching of values for the wrapped methods, based on a set of generic
+algorithms for computing hashable values based on the method's arguments.
+This collected caching logic nicely, but had two drawbacks:
+
+    Running arguments through a generic key-conversion mechanism is slower
+    (and less flexible) than just coding these things directly.  Since the
+    methods that need memoized values are generally performance-critical,
+    slowing them down in order to collect the logic isn't the right
+    tradeoff.
+
+    Use of the memoizer really obscured what was being called, because
+    all the memoized methods were wrapped with re-used generic methods.
+    This made it more difficult, for example, to use the Python profiler
+    to figure out how to optimize the underlying methods.

+    hits and misses, which is very valuable.
+
+    Lookup keys in the cache are computed by the _PathList_key() method.
+    Cache lookup should be quick, so we don't spend cycles canonicalizing
+    all forms of the same lookup key.  For example, 'x:y' and ['x',
+    'y'] logically represent the same list, but we don't bother to
+    split string representations and treat those two equivalently.
+    (Note, however, that we do, treat lists and tuples the same.)
+
+    The main type of duplication we're trying to catch will come from
+    looking up the same path list from two different clones of the
+    same construction environment.  That is, given
+    
+        env2 = env1.Clone()
+
+    both env1 and env2 will have the same CPPPATH value, and we can
+    cheaply avoid re-parsing both values of CPPPATH by using the
+    common value from this cache.

+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.

+#   USE, INTRINSIC :: module_name
+#   USE, NON_INTRINSIC :: module_name
+#
+#   Limitations
+#
+#   --  While the regex can handle multiple USE statements on one line,

+#       In either of the following cases:

+#       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

+#       compiler-specific directories we will need to point to so the
+#       compiler and SCons can locate the proper object and mod files?
+

+#            ,         : match a comma

+#            INTRINSIC : match the string INTRINSIC, case insensitive
+#         )?           : optionally match the ", INTRINSIC/NON_INTRINSIC" grouped expression
+#         \s*          : any amount of white space
+#         ::           : match a double colon that must appear after the INTRINSIC/NON_INTRINSIC attribute
+#      )               : end the unsaved grouping
+#   )                  : end the unsaved grouping

+
+
+#   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

+#                        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,

+#                        is required so that the include delimiter is

+    Unlike most scanners, which use regular expressions that just
+    return the included file name, this returns a tuple consisting
+    of the keyword for the inclusion ("include", "includegraphics",
+    "input", or "bibliography"), and then the file name itself.  
+    Based on a quick look at LaTeX documentation, it seems that we 
+    should append .tex suffix for the "include" keywords, append .tex if
+    there is no extension for the "input" keyword, and need to add .bib
+    for the "bibliography" keyword that does not accept extensions by itself.
+
+    Finally, if there is no extension for an "includegraphics" keyword
+    latex will append .ps or .eps to find the file, while pdftex may use .pdf,
+    .jpg, .tif, .mps, or .png.
+    
+    The actual subset and search order may be altered by
+    DeclareGraphicsExtensions command. This complication is ignored.
+    The default order corresponds to experimentation with teTeX
+        $ latex --version
+        pdfeTeX 3.141592-1.21a-2.2 (Web2C 7.5.4)
+        kpathsea version 3.5.4
+    The order is:
+        ['.eps', '.ps'] for latex
+        ['.png', '.pdf', '.jpg', '.tif'].
+
+    Another difference is that the search path is determined by the type
+    of the file being searched:
+    env['TEXINPUTS'] for "input" and "include" keywords
+    env['TEXINPUTS'] for "includegraphics" keyword
+    env['TEXINPUTS'] for "lstinputlisting" keyword
+    env['BIBINPUTS'] for "bibliography" keyword
+    env['BSTINPUTS'] for "bibliographystyle" keyword
+    env['INDEXSTYLE'] for "makeindex" keyword, no scanning support needed

+
+        'path_function' - a function that takes four or five arguments

+
+        'scan_check' - a function to be called to first check whether

+
+        'recursive' - specifies that this scanner should be invoked

+# 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.

+
+  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.

+  across different drives on windows. We assume here, that single local
+  filesystem holds both source files and target `POT` templates.

+
+Tool-specific initialization for the Digital Mars D compiler.
+(http://digitalmars.com/d)
+
+Coded by Andy Friesen (andy@ikagames.com)
+15 November 2003
+
+Amended by Russel Winder (russel@russel.org.uk)
+2010-02-07
+
+There are a number of problems with this script at this point in time.
+The one that irritates me 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.
+    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)
