What is the Knowledgebase?
The POV-Ray Knowledgebase is a collection of information related to fixing issues that are encountered in the use of POV-Ray. This does not include just bugs in POV-Ray, but really any sort of issue that might create a barrier to further progress in developing a particular scene, or in using POV-Ray in general.
The knowledgebase is not a substitute for the how-tos - it does not serve as a set of tutorials. As a general rule, knowledgebase articles are expected to be fairly short.
