-23 October 2003
-Fixed bug where a class would appear more than one in the generated code.
-
-6 October 2003
-Fixed bug reported by Niall Douglas (using his patch) about UniqueInt not
-appearing correctly with --multiple.
-
-Added precompiled header support on windows systems (using #pragma hdrstop).
-Suggested by Niall Douglas.
-
-Fixed a bug with -I directive and AllFromHeader. Reported by Scott Snyder.
-
-4 October 2003
-Added return_self, thanks for Niall Douglas for pointing out that it was
-missing.
-
-Added --file-list, where you can pass a file where the pyste files are listed
-one per line. Also suggested by Niall Douglas.
-
-Documentation has been finally updated, after a long wait. Please let me know
-if you spot any mistake!
-
-2 October 2003
-Scott Snyder found a typo in ClassExporter that prevented -= and *= operators
-from being exported. Thanks Scott!
-
-20 September 2003
-Added return_by_value in the list of policies supported. Thanks to Niall
-Douglas for the remainder.
-
-19 September 2003
-Better support for unnamed enums, plus they are by default exported to the
-parent's namespace. Normal enums can have the same behaviour using the function
-export_values on the Enum object. Feature requested by Niall Douglas.
-
-10 September 2003
-A new variable is accessible in the Pyste files: INTERFACE_FILE contains the 
-full path of the pyste file.
-
-4 September 2003
-Now it is possible to override protected and private pure virtual functions
-in Python, as requested by Roman Yakovenko.
-
-23 August 2003
-Fixed bug where some Imports where not writing their include files.  
-Now whenever the declarations change, the cache files are rebuilt
-automatically.
-
-19 August 2003
-Fixed a bug related to the generation of the bases<> template.
-
-17 August 2003
-Added support for insertion of user code in the generated code.
-
-16 August 2003
-Applied a patch by Gottfried Ganssauge that adds exception specifiers to 
-wrapper functions and pointer declarations. Thanks a lot Gottfried!!
-
-Applied a patch by Prabhu Ramachandran that fixes ae problem with the 
-pure virtual method generation. Thanks again Prabhu!
-
-10 August 2003
-Support for incremental generation of the code has been added. This changes
-how --multiple works; documentation of this new feature will follow. Thanks
-to Prabhu Ramachandran, that saw the need for this feature and discussed a
-solution. 
-
-Automatically convert \ to / in Windows systems before passing the paths to
-gccxml.
-
-Fixed a bug reported by Prabhu Ramachandran, where in some classes the virtual
-methods were being definied incorrectly. Thanks a lot Prabhu!
-
-7 July 2003
-Applied 2 patches by Prabhu Ramachandran: a fix in the new --multiple method,
-and two new functions "hold_with_shared_ptr" and its counterpart for auto_ptr.
-Thanks a lot Prabhu!
-
-Fixed a bug where the macro BOOST_PYTHON_OPAQUE_SPECIALIZED_TYPE_ID was being
-called multiple times for the same type.
-Thanks to Gottfried Ganßauge for reporting this!
-
-Fixed bug where using AllFromHeader didn't use bases<> when exporting 
-hierarchies.
-
-Fixed the staticmethod bug.
-
-5 July 2003
-Changed how --multiple works: now it generates one cpp file for each pyste
-file, makeing easier to integrate Pyste with build systems.

-Applied patch that solved a bug in ClassExporter and added a distutils install
-script (install/setup.py), both contributed by Prabhu Ramachandran.
-Thanks Prabhu!

-Jim Wilson found a bug where types like "char**" were being interpreted as 
-"char*". Thanks Jim!

-16 June 2003
-Thanks to discussions with David Abrahams and Roman Sulzhyk, some behaviours
-have changed:
-
-- If you export a derived class without exporting its base classes, the derived
-  class will explicitly export the bases's methods and attributes. Before, if
-  you were interested in the bases's methods, you had to export the base
-  classes too.
-
-- Added a new function, no_override. When a member function is specified as
-  "no_override", no virtual wrappers are generated for it, improving
-  performance and letting the code more clean.
-
-- There was a bug in which the policy of virtual member functions was being
-  ignored (patch by Roman Sulzhyk). 
-  
-Thanks again to Roman Sulzhyk for the patches and discussion in the c++-sig.

-Major improvements in memory usage.
-
-3 June 2003
-Appliced a patch from Giulio Eulisse that allows unnamed enumerations to be
-exported with an AllFromHeader construct. Thanks a lot Giulio!
-
-2 June 2003
-Added a new construct, add_method. See documentation.
-
-23 May 2003
-Support for global variables added.
-Various bug fixes.
-
-08 May 2003
-Fixed bug where in a certain cases the GCCXMLParser would end up with multiple
-declarations of the same class
-
-22 Apr 2003
-- Now shows a warning when the user tries to export a forward-declared class.
-  Forward-declared classes are ignored by the AllFromHeader construct.
-- Fixed a bug where classes, functions and enums where being exported, even if
-  excluded from a AllFromHeader construct.
-
-16 Apr 2003
-Added a more generic (but ugly) code to declare the smart pointer converters.
-
-07 Apr 2003
-- Removed the warnings about forward declarations: it was not accurate enough.
-  Another strategy must be thought of.
-- Fixed bug in the --multiple mode, where the order of the class instantiations
-  could end up wrong.
-- Lots of fixes in the documentation, pointed out by Dirk Gerrits. Thanks Dirk!
-- Fixed support for the return_opaque_pointer policy (the support macro was not
-  being declared).

-
-24 Mar 2003
-Default policy for functions/methods that return const T& is now
-return_value_policy<copy_const_reference>().
-
-22 Mar 2003
-Exporting virtual methods of the base classes in the derived classes too.
-
-21 Mar 2003
-Added manual support for boost::shared_ptr and std::auto_ptr (see doc).
-
-19 Mar 2003 
-Added support for int, double, float and long operators acting as expected in
-python.
-
