+		DGNLIB Source Distribution
+		==========================
+
+Current information on DGNLIB, including detailed API documentation
+can be found at:
+
+  http://dgnlib.maptools.org/
+
+
+Building
+--------
+
+This is a preliminary source distribution, and I have not gone to any
+pains to make it easy to configure and build.  To build please do the 
+following:
+
+== Unix:
+
+1. Update cpl_config.h to represent your platform accurately.  Generally all
+that matters is to #define WORDS_BIGENDIAN on big endian platforms.  The
+rest can likely be ignored.<p>
+
+2. Build the programs. 
+
+  % make 
+
+== Windows:
+
+1. Ensure you have Microsoft Visual C++ 6.x or later installed.
+
+2. Ensure the commandline VC++ environment is setup properly.  You may need
+   to run the VCVARS32.BAT script from within the VC++ tree. 
+
+3. Compile the code, and build statically linked executables for the sample
+   programs and DLL using the following command.
+
+   nmake /f makefile.vc
+
+
+
+Release Notes
+=============
+
+Release 1.11
+------------
+
+ o B-Spline support:
+   - The DGNT_BSPLINE define was bogus, replaced with DGNT_BSPLINE_POLE.
+   - Added support for the following B-Spline related elements:
+     o DGNElemBSplineSurfaceHeader (24)
+     o DGNElemBSplineCurveHeader (27)
+     o DGNElemBSplineSurfaceBoundary (25)
+     o DGNElemKnotWeight (26/28)
+
+ o Added initial support for Shared Cell Definition elements
+
+ o 3D solid/surface fixes:
+   - Fixed incorrect reading and writing of surftype field.
+   - Added boundelms field to DGNElemComplexHeader
+   - Added DGNCreateSolidHeaderElem() and DGNCreateSolidHeaderElemFromGroup()
+   - Changed DGNCreateComplexHeaderElem() and 
+     DGNCreateComplexHeaderElemFromGroup() to only support complex chains/shapes
+   - Fixed bug creating solids/surfaces: totlength was 1 word too short.
+   - Renamed bogus define DGNSUT_SOLID to DGNSUT_SURFACE_OF_PROJECTION
+
+ o Added support for cloning Cone elements
+
+ o Fixes for uor handling in DGNCreate(). 
+
+ o Treat the most recently read color table as the global color table, 
+   instead of just the first one encountered.
+
+ o Added Text Node implementation from Ilya Beylin. 
+
+
+Release 1.10
+------------
+
+ o Added DGNElemTypeHasDispHdr(), and use it in DGNParseCore() to avoid trying
+   to read disp hdr, or attributes from inappropriate elements.
+
+ o Check if a negative amount of attribute information is being read in
+   DGNParseCore(), and if so just issue a warning, and skip attempt.
+
+ o Fixed DGNCreateCellHeaderFromGroup() to not pre-transform the bounds.  
+
+ o Fixed missing handling of min/max Z in DGNCreateMultiPointElem(). (Marius)
+
+ o Added surface type to DGNCreateComplexHeaderElem().  (Marius)
+
+ o DGNRad50ToAscii() reimplemented to correct a few problems.  New version
+   provided by Armin Berg (iez.com). 
+
+ o Fixes to complex header and cell header creation to set the total group
+   size properly, and to set up complex header pad attributes properly.  Now
+   passed EDG validation.
+
+
+Release 1.9
+-----------
+
+ o Added DGNLoadTCB(), and fixed problem when writing new elements to an
+   existing file without having already read the TCB. 
+
+ o Fixed serious bug in setting the index "offset" location.  Critical for
+   writing applications.
+
+
+Release 1.8
+-----------
+
+ o Added support for reading 3D cone (23), 3D surface (18) and 3D solid (19) 
+   elements based on contributions from Marius Kintel. 
+
+ o Main site moved to http://dgnlib.maptools.org/
+
+
+Release 1.7
+-----------
+
+ o Improved calcuation of bounding box in DGLCreateTextElem() based on code
+   from Matt Kelder. 
+
+ o Added preliminary 3D write support. 
+
+ o Modified DGNCreateTextElem() arguments, and deprecated DGNCreateArcElem2D()
+   in favour of DGNCreateArcElem().
+
+ o Report transformation matrix for ViewInfo when dumping.
+
+
+Release 1.6
+-----------
+
+ o Bug fix in DGNGetLinkage() for DMRS recognition from Henk Jan Priester.
+
+ o Added DGNCreateCellHeaderFromGroup() and DGNCreateCellHeaderElem() 
+   functions in the write API.
+
+ o Added a Microsoft VC++ makefile (Makefile.vc). 
+
+
+Release 1.5
+-----------
+
+ o Added 2D write support!  
+
+ o Fixed collection of background color in color table (color 255) as per
+   bug report by Henk Jan Priester (Justcroft Technical Systems). 
+
+ o Added support for association ids (DGNLT_ASSOC_ID, DGNGetAssocID()). 
+
+ o Fixed problem with updating the DGNInfo.color_table field when a color
+   table is read. 
+
+ o Fixed problem with spatial queries either including all of a complex
+   element (and it's members) or none. 
+
+ o Added support for reading the eight view descriptions in the TCB element.
+
+ o Added a Makefile in the source distribution.
+
+ o Fixed error with tags in DGNFreeElement() as reported by Henk Jan Priester.
+
+
+
+Release 1.4
+-----------
+
+ o Added "fast" spatial searching via the DGNSetSpatialFilter() function. 
+   This basically just reads the extents information at beginning of 
+   geometric features to see if they should be returned. 
+
+ o Actually extract the global origin from the TCB, and use it when 
+   transforming points.  Only a few files (ie. Brazos County roads.rds) use
+   a non-zero origin.
+
+ o Added experimental multi byte text support from Ason Kang
+   ([email protected]). 
+
+ o Add experimental support for 3D files.  Somes 3d elements not supported. 
+   3d quaterion for ellipse and arc elements not utilized. 
+
+ o Added preliminary support for reading cell header structures based
+   on input from Mike Cane. 
+
+ o Moved a bunch of stuff into dgnread.cpp. 
+
+ o Build default colortable into dgnhelp.cpp for use of DGNLookupColor(). 
+
+ o Added DGNGetShapeFillInfo(). 
+
+ o DGNGetShapeFillInfo() now tries to handle multi-part attribute linkages.
+
+
+Release 1.3
+-----------
+
+ o Added raw_data/raw_bytes members of DGNElemCore, and DGNSetOptions()
+   to allow control of when raw element image is retained. 
+
+ o Added -r flag to dgndump to dump raw contents of desired elements. 
+
+ o Add CPL_CVSID() to simplify tracking of versions. 
+
+ o Fixed bug with freeing element index in DGNClose().
