-"""gypd output module
-
-This module produces gyp input as its output.  Output files are given the
-.gypd extension to avoid overwriting the .gyp files that they are generated
-from.  Internal references to .gyp files (such as those found in
-"dependencies" sections) are not adjusted to point to .gypd files instead;
-unlike other paths, which are relative to the .gyp or .gypd file, such paths
-are relative to the directory from which gyp was run to create the .gypd file.
-
-This generator module is intended to be a sample and a debugging aid, hence
-the "d" for "debug" in .gypd.  It is useful to inspect the results of the
-various merges, expansions, and conditional evaluations performed by gyp
-and to see a representation of what would be fed to a generator module.
-
-It's not advisable to rename .gypd files produced by this module to .gyp,
-because they will have all merges, expansions, and evaluations already
-performed and the relevant constructs not present in the output; paths to
-dependencies may be wrong; and various sections that do not belong in .gyp
-files such as such as "included_files" and "*_excluded" will be present.
-Output will also be stripped of comments.  This is not intended to be a
-general-purpose gyp pretty-printer; for that, you probably just want to
-run "pprint.pprint(eval(open('source.gyp').read()))", which will still strip
-comments but won't do all of the other things done to this module's output.
-
-The specific formatting of the output generated by this module is subject
-to change.

-        the different configurations (Debug, Release) under which this

-"""Xcode project file generator.
-
-This module is both an Xcode project file generator and a documentation of the
-Xcode project file format.  Knowledge of the project file format was gained
-based on extensive experience with Xcode, and by making changes to projects in
-Xcode.app and observing the resultant changes in the associated project files.
-
-XCODE PROJECT FILES
-
-The generator targets the file format as written by Xcode 3.1 (specifically,
-3.1.2), but past experience has taught that the format has not changed
-significantly in the past several years, and future versions of Xcode are able
-to read older project files.
-
-Xcode project files are "bundled": the project "file" from an end-user's
-perspective is actually a directory with an ".xcodeproj" extension.  The
-project file from this module's perspective is actually a file inside this
-directory, always named "project.pbxproj".  This file contains a complete
-description of the project and is all that is needed to use the xcodeproj.
-Other files contained in the xcodeproj directory are simply used to store
-per-user settings, such as the state of various UI elements in the Xcode
-application.
-
-The project.pbxproj file is a property list, stored in a format almost
-identical to the NeXTstep property list format.  The file is able to carry
-Unicode data, and is encoded in UTF-8.  The root element in the property list
-is a dictionary that contains several properties of minimal interest, and two
-properties of immense interest.  The most important property is a dictionary
-named "objects".  The entire structure of the project is represented by the
-children of this property.  The objects dictionary is keyed by unique 96-bit
-values represented by 24 uppercase hexadecimal characters.  Each value in the
-objects dictionary is itself a dictionary, describing an individual object.
-
-Each object in the dictionary is a member of a class, which is identified by
-the "isa" property of each object.  A variety of classes are represented in a
-project file.  Objects can refer to other objects by ID, using the 24-character
-hexadecimal object key.  A project's objects form a tree, with a root object
-of class PBXProject at the root.  As an example, the PBXProject object serves
-as parent to an XCConfigurationList object defining the build configurations
-used in the project, a PBXGroup object serving as a container for all files
-referenced in the project, and a list of target objects, each of which defines
-a target in the project.  There are several different types of target object,
-such as PBXNativeTarget and PBXAggregateTarget.  In this module, this
-relationship is expressed by having each target type derive from an abstract
-base named XCTarget.
-
-The project.pbxproj file's root dictionary also contains a property, sibling to
-the "objects" dictionary, named "rootObject".  The value of rootObject is a
-24-character object key referring to the root PBXProject object in the
-objects dictionary.
-
-In Xcode, every file used as input to a target or produced as a final product
-of a target must appear somewhere in the hierarchy rooted at the PBXGroup
-object referenced by the PBXProject's mainGroup property.  A PBXGroup is
-generally represented as a folder in the Xcode application.  PBXGroups can
-contain other PBXGroups as well as PBXFileReferences, which are pointers to
-actual files.
-
-Each XCTarget contains a list of build phases, represented in this module by
-the abstract base XCBuildPhase.  Examples of concrete XCBuildPhase derivations
-are PBXSourcesBuildPhase and PBXFrameworksBuildPhase, which correspond to the
-"Compile Sources" and "Link Binary With Libraries" phases displayed in the
-Xcode application.  Files used as input to these phases (for example, source
-files in the former case and libraries and frameworks in the latter) are
-represented by PBXBuildFile objects, referenced by elements of "files" lists
-in XCTarget objects.  Each PBXBuildFile object refers to a PBXBuildFile
-object as a "weak" reference: it does not "own" the PBXBuildFile, which is
-owned by the root object's mainGroup or a descendant group.  In most cases, the
-layer of indirection between an XCBuildPhase and a PBXFileReference via a
-PBXBuildFile appears extraneous, but there's actually one reason for this:
-file-specific compiler flags are added to the PBXBuildFile object so as to
-allow a single file to be a member of multiple targets while having distinct
-compiler flags for each.  These flags can be modified in the Xcode applciation
-in the "Build" tab of a File Info window.
-
-When a project is open in the Xcode application, Xcode will rewrite it.  As
-such, this module is careful to adhere to the formatting used by Xcode, to
-avoid insignificant changes appearing in the file when it is used in the
-Xcode application.  This will keep version control repositories happy, and
-makes it possible to compare a project file used in Xcode to one generated by
-this module to determine if any significant changes were made in the
-application.
-
-Xcode has its own way of assigning 24-character identifiers to each object,
-which is not duplicated here.  Because the identifier only is only generated
-once, when an object is created, and is then left unchanged, there is no need
-to attempt to duplicate Xcode's behavior in this area.  The generator is free
-to select any identifier, even at random, to refer to the objects it creates,
-and Xcode will retain those identifiers and use them when subsequently
-rewriting the project file.  However, the generator would choose new random
-identifiers each time the project files are generated, leading to difficulties
-comparing "used" project files to "pristine" ones produced by this module,
-and causing the appearance of changes as every object identifier is changed
-when updated projects are checked in to a version control repository.  To
-mitigate this problem, this module chooses identifiers in a more deterministic
-way, by hashing a description of each object as well as its parent and ancestor
-objects.  This strategy should result in minimal "shift" in IDs as successive
-generations of project files are produced.
-
-THIS MODULE
-
-This module introduces several classes, all derived from the XCObject class.
-Nearly all of the "brains" are built into the XCObject class, which understands
-how to create and modify objects, maintain the proper tree structure, compute
-identifiers, and print objects.  For the most part, classes derived from
-XCObject need only provide a _schema class object, a dictionary that
-expresses what properties objects of the class may contain.
-
-Given this structure, it's possible to build a minimal project file by creating
-objects of the appropriate types and making the proper connections:
-
-  config_list = XCConfigurationList()
-  group = PBXGroup()
-  project = PBXProject({'buildConfigurationList': config_list,
-                        'mainGroup': group})
-
-With the project object set up, it can be added to an XCProjectFile object.
-XCProjectFile is a pseudo-class in the sense that it is a concrete XCObject
-subclass that does not actually correspond to a class type found in a project
-file.  Rather, it is used to represent the project file's root dictionary.
-Printing an XCProjectFile will print the entire project file, including the
-full "objects" dictionary.
-
-  project_file = XCProjectFile({'rootObject': project})
-  project_file.ComputeIDs()
-  project_file.Print()
-
-Xcode project files are always encoded in UTF-8.  This module will accept
-strings of either the str class or the unicode class.  Strings of class str
-are assumed to already be encoded in UTF-8.  Obviously, if you're just using
-ASCII, you won't encounter difficulties because ASCII is a UTF-8 subset.
-Strings of class unicode are handled properly and encoded in UTF-8 when
-a project file is output.

-                      to a single element.
-             property_type: The type to use as the value of the property,
-                            or if is_list is True, the type to use for each
-                            element of the value's list.  property_type must

-             is_strong: If property_type is an XCObject subclass, is_strong
-                        is True to assert that this class "owns," or serves
-                        as parent, to the property value (or, if is_list is
-                        True, values).  is_strong must be False if
-                        property_type is not an XCObject subclass.
-             is_required: True if the property is required for the class.

-                          an empty string ("", in the case of property_type
-                          str) or list ([], in the case of is_list True) from
-                          being set for the property.
-             default: Optional.  If is_requried is True, default may be set
-                      to provide a default value for objects that do not supply
-                      their own value.  If is_required is True and default
-                      is not provided, users of the class must supply their own
-                      value for the property.
-             Note that although the values of the array are expressed in
-             boolean terms, subclasses provide values as integers to conserve
-             horizontal space.
-    _should_print_single_line: False in XCObject.  Subclasses whose objects
-                               should be written to the project file in the
-                               alternate single-line format, such as
-                               PBXFileReference and PBXBuildFile, should
-                               set this to True.
-    _encode_transforms: Used by _EncodeString to encode unprintable characters.
-                        The index into this list is the ordinal of the
-                        character to transform; each value is a string
-                        used to represent the character in the output.  XCObject
-                        provides an _encode_transforms list suitable for most
-                        XCObject subclasses.
-    _alternate_encode_transforms: Provided for subclasses that wish to use
-                                  the alternate encoding rules.  Xcode seems
-                                  to use these rules when printing objects in
-                                  single-line format.  Subclasses that desire
-                                  this behavior should set _encode_transforms
-                                  to _alternate_encode_transforms.
-    _hashables: A list of XCObject subclasses that can be hashed by ComputeIDs
-                to construct this object's ID.  Most classes that need custom
-                hashing behavior should do it by overriding Hashables,
-                but in some cases an object's parent may wish to push a
-                hashable value into its child, and it can do so by appending
-                to _hashables.
-  Attribues:
-    id: The object's identifier, a 24-character uppercase hexadecimal string.
-        Usually, objects being created should not set id until the entire
-        project file structure is built.  At that point, UpdateIDs() should
-        be called on the root object to assign deterministic values for id to
-        each object in the tree.
-    parent: The object's parent.  This is set by a parent XCObject when a child
-            object is added to it.
-    _properties: The object's property dictionary.  An object's properties are
-                 described by its class' _schema variable.

-    the hierarchical structure changes (possibly due to changes caused when

-    the hashes will change.  For example, if a project file initially contains

-    a/b.  If someone later adds a/f2 to the project file, a/b can no longer be
-    collapsed, and f1 winds up with parent b and grandparent a.  That would
-    be sufficient to change f1's hash.
-
-    To counteract this problem, hashables for all XCHierarchicalElements except
-    for the main group (which has neither a name nor a path) are taken to be
-    just the set of path components.  Because hashables are inherited from
-    parents, this provides assurance that a/b/f1 has the same set of hashables
-    whether its parent is b or a/b.
-
-    The main group is a special case.  As it is permitted to have no name or
