        Abstract
        --------
        
        A Python package to create and modify DXF drawings, independent from the DXF
        version. You can open/save every DXF file without loosing any content (except comments),
        Unknown tags in the DXF file will be ignored but preserved for saving. With this behavior
        it is possible to open also DXF drawings that contains data from 3rd party applications.
        
        Quick-Info
        ----------
        
        - ezdxf is a Python package to create new DXF files and read/modify/write existing DXF files
        - the intended audience are developers
        - requires Python 2.7 or later, runs on CPython and pypy, maybe on IronPython and Jython
        - OS independent
        - additional required packages: `pyparsing <https://pypi.python.org/pypi/pyparsing/2.0.1>`_
        - MIT-License
        - read/write/new support for DXF versions: R12, R2000, R2004, R2007, R2010, R2013 and R2018
        - additional read support for DXF versions R13/R14 (upgraded to R2000)
        - additional read support for older DXF versions than R12 (upgraded to R12)
        - preserves third-party DXF content
        - additional fast DXF R12 writer, that creates just an ENTITIES section with support for the basic DXF entities
        
        a simple example::
        
            import ezdxf
        
            drawing = ezdxf.new(dxfversion='AC1024')  # or use the AutoCAD release name ezdxf.new(dxfversion='R2010')
            modelspace = drawing.modelspace()
            modelspace.add_line((0, 0), (10, 0), dxfattribs={'color': 7})
            drawing.layers.new('TEXTLAYER', dxfattribs={'color': 2})
            # use set_pos() for proper TEXT alignment - the relations between halign, valign, insert and align_point are tricky.
            modelspace.add_text('Test', dxfattribs={'layer': 'TEXTLAYER'}).set_pos((0, 0.2), align='CENTER')
            drawing.saveas('test.dxf')
        
        example for the *r12writer*, writes a simple DXF R12 file without in-memory structures::
        
            from random import random
            from ezdxf.r12writer import r12writer
        
            MAX_X_COORD = 1000.0
            MAX_Y_COORD = 1000.0
            CIRCLE_COUNT = 100000
        
            with r12writer("many_circles.dxf") as dxf:
                for i in range(CIRCLE_COUNT):
                    dxf.add_circle((MAX_X_COORD*random(), MAX_Y_COORD*random()), radius=2)
        
        The r12writer supports only the ENTITIES section of a DXF R12 drawing, no HEADER, TABLES or BLOCKS section is
        present, except FIXED-TABLES are written, than some additional predefined text styles and line types are available.

           * Release notes: https://ezdxf.mozman.at/release-v0-8-7.html
           * NEW: entity.get_layout() returns layout in which entity resides or None if unassigned

           * NEW: Table(), MText(), Ellipse(), Spline(), Bezier(), Clothoid(), LinearDimension(), RadialDimension(),
             ArcDimension() and AngularDimension() composite objects from dxfwrite as add-ons, these add-ons support DXF R12
           * NEW: geometry builder as add-ons: MeshBuilder(), MeshVertexMerger(), MengerSponge(), SierpinskyPyramid(), these

           * added subclass marker filter for R12 and prior files in legacy_mode=True (required for malformed DXF files)
           * removed special check for Leica Disto Unit files, use readfile(filename, legacy_mode=True) (malformed DXF R12 file,
             see previous point)
        
        Version 0.8.4 - 2018-01-14

          * NEW: DXF file structure validator at SECTION level, tags outside of sections will be removed
          * NEW: Basic read support for DIMENSION
          * CHANGE: improved exception management, in the future ezdxf should only raise exceptions inherited from DXFError for
            DXF related errors, previous exception classes still work
        
            - DXFValueError(DXFError, ValueError)
            - DXFKeyError(DXFError, KeyError)
            - DXFAttributeError(DXFError, AttributeError)
            - DXFIndexError(DXFError, IndexError)
            - DXFTableEntryError(DXFValueError)
        
          * speedup low level tag reader around 5%, and speedup tag compiler around 5%
        
        Version 0.8.3 - 2018-01-02
        
          * CHANGE: Lwpolyline - suppress yielding z coordinates if they exists (DXFStructureError: z coordinates are not defined in the DXF standard)
          * NEW: setup creates a script called 'dxfpp' (DXF Pretty Printer) in the Python script folder
          * NEW: basic support for DXF format AC1032 introduced by AutoCAD 2018
          * NEW: ezdxf use logging and writes all logs to a logger called 'ezdxf'. Logging setup is the domain of the application!
          * NEW: warns about multiple block definitions with the same name in a DXF file. (DXFStructureError)
          * NEW: legacy_mode parameter in ezdxf.read() and ezdxf.readfile(): tries do fix coordinate order in LINE
            entities (10, 11, 20, 21) by the cost of around 5% overall speed penalty at DXF file loading
        
        Version 0.8.2 - 2017-05-01
        
          * NEW: Insert.delete_attrib(tag) - delete ATTRIB entities from the INSERT entity
          * NEW: Insert.delete_all_attribs() - delete all ATTRIB entities from the INSERT entity
          * BUGFIX: setting attribs_follow=1 at INSERT entity before adding an attribute entity works
        
        Version 0.8.1 - 2017-04-06
        
          * NEW: added support for constant ATTRIB/ATTDEF to the INSERT (block reference) entity
          * NEW: added ATTDEF management methods to BlockLayout (has_attdef, get_attdef, get_attdef_text)
          * NEW: added (read/write) properties to ATTDEF/ATTRIB for setting flags (is_const, is_invisible, is_verify, is_preset)
        
        Version 0.8.0 - 2017-03-28
        
          * added groupby(dxfattrib='', key=None) entity query function, it is supported by all layouts and the query result
            container: Returns a dict, where entities are grouped by a dxfattrib or the result of a key function.
          * added ezdxf.audit() for DXF error checking for drawings created by ezdxf - but not very capable yet
          * dxfattribs in factory functions like add_line(dxfattribs=...), now are copied internally and stay unchanged, so they
            can be reused multiple times without getting modified by ezdxf.
          * removed deprecated Drawing.create_layout() -> Drawing.new_layout()
          * removed deprecated Layouts.create() -> Layout.new()
          * removed deprecated Table.create() -> Table.new()
          * removed deprecated DXFGroupTable.add() -> DXFGroupTable.new()
          * BUFIX in EntityQuery.extend()
        
        Version 0.7.9 - 2017-01-31
        
          * BUGFIX: lost data if model space and active layout are called \*MODEL_SPACE and \*PAPER_SPACE
        
        Version 0.7.8 - 2017-01-22
        
          * BUGFIX: HATCH accepts SplineEdges without defined fit points
          * BUGFIX: fixed universal line ending problem in ZipReader()
          * Moved repository to GitHub: https://github.com/mozman/ezdxf.git
        
        Version 0.7.7 - 2016-10-22
        
          * NEW: repairs malformed Leica Disto DXF R12 files, ezdxf saves a valid DXF R12 file.
          * NEW: added Layout.unlink(entity) method: unlinks an entity from layout but does not delete entity from the drawing database.
          * NEW: added Drawing.add_xref_def(filename, name) for adding external reference definitions
          * CHANGE: renamed parameters for EdgePath.add_ellipse() - major_axis_vector -> major_axis; minor_axis_length -> ratio
            to be consistent to the ELLIPSE entity
          * UPDATE: Entity.tags.new_xdata() and Entity.tags.set_xdata() accept tuples as tags, no import of DXFTag required
          * UPDATE: EntityQuery to support both 'single' and "double" quoted strings - Harrison Katz <harrison@neadwerx.com>
          * improved DXF R13/R14 compatibility
