*
* $Log$
* Revision 1.1 2004/03/13 23:43:02 rpedde
* Add Damian Ivereigh's redblack tree implementation to speed lookups
*
* Revision 1.9 2003/10/24 01:31:21 damo
* Patches from Eric Raymond: %prefix is implemented.  Various other small
* changes avoid stepping on global namespaces and improve the documentation.
*
* Revision 1.8 2003/10/23 04:18:47 damo
* Fixed up the rbgen stuff ready for the 1.3 release
*
* Revision 1.7 2002/08/26 03:11:40 damo
* Fixed up a bunch of compiler warnings when compiling example4
*
* Tidies up the Makefile.am & Specfile.
*
* Renamed redblack to rbgen
*
* Revision 1.6 2002/08/26 01:03:35 damo
* Patch from Eric Raymond to change the way the library is used:-
*
* Eric's idea is to convert libredblack into a piece of in-line code
* generated by another program. This should be faster, smaller and easier
* to use.
*
* This is the first check-in of his code before I start futzing with it!
*
* Revision 1.5 2002/01/30 07:54:53 damo
* Fixed up the libtool versioning stuff (finally)
* Fixed bug 500600 (not detecting a NULL return from malloc)
* Fixed bug 509485 (no longer needs search.h)
* Cleaned up debugging section
* Allow multiple inclusions of redblack.h
* Thanks to Matthias Andree for reporting (and fixing) these
*
* Revision 1.4 2000/06/06 14:43:43 damo
* Added all the rbwalk & rbopenlist stuff. Fixed up malloc instead of sbrk.
* Added two new examples
*
* Revision 1.3 2000/05/24 06:45:27 damo
* Converted everything over to using const
* Added a new example1.c file to demonstrate the worst case scenario
* Minor fixups of the spec file
*
* Revision 1.2 2000/05/24 06:17:10 damo
* Fixed up the License (now the LGPL)
*
* Revision 1.1 2000/05/24 04:15:53 damo
* Initial import of files. Versions are now all over the place. Oh well
*
