++NOTE: The TDE project has take over maintinance of this library,
++starting with the sources from the final upstream release v2.3.21.

++This allows the TDE project to resolve remaining issues that cause
++problems or crashes within TDE.
++
++This patched library is only available under the terms of the
++GPL/LGPL, and is NOT for sale by the original author as mentioned
++above, as patch copyright has NOT been transferred to the original
++author and we have no plans to do so.
