 STEP Class Library  ------  http://github.com/mpictor/StepClassLibrary
 ************************************************************************
+Release 0.5 (Feb 23, 2012)
+
+New since v0.4:
+* MSVC and Embarcadero support, along with many warning fixes
+* Experimental Python support
+* Now handles most features of EXPRESS - all included schemas,
+  with the exception of AP209 CD, are parsed without error. Enums are
+  now in their own dictionary. Allow indexing on aggregates, generics,
+  and binaries. 
+* Changes to fedex_plus that improve the generated c++ - use a
+  namespace, break up large static strings, make EXPRESS multiple
+  inheritance work by not printing multiple copies of inherited members.
+  All schemas now compile without error, but there are numerous warnings.
+* Exchange files: handle all comments, fill in some missing attributes.
+* More cleanup of source code, more documentation in scl/doc
+* Special thanks to @davyw and @tpaviot for their large contributions
+  (MSVC and Python, respectively)

 * What is SCL? SCL reads ISO10303-11 EXPRESS schemas and generates
-  C++ source code that can read and write Part 21 files conforming 
-  to that schema. SCL once worked with ObjectStore, OODB, and
-  CORBA IDL - but that code has not been used in a very long time.
-  We are in the process of removing this code because ObjectStore,
-  CORBA, etc. are no longer part of the STEP standard.
+  C++ source code that can read and write Part 21 files conforming

+  support for Python.
  
 * SCL is packaged along with some other tools. See

-* Build options (append to the 'cmake ..' line):
-  -DBUILD_SCHEMAS="path/to/schema.exp;path/to/schema2.exp" 
-    - this generates c++ for the schema, and compiles it into a
-      library. Also works with directories, as long as each dir only
-      has one express file.
-    - multiple files/directories are separated by semicolons
-    - this also builds a 'p21read' program, which reads one step file
-      and writes another. It may change whitespace or remove comments;
-      otherwise, the input and output files should be identical. If
-      they are not identical, either the file does not match the
-      schema, or SCL generated incorrect source code.
-   -DBUILD_SCHEMAS=ALL
-    - Added to make use of ctest easier. If BUILD_SCHEMAS == ALL,
-      then CMake adds each *.exp file found in data/.
