Some changes were made to the API when making the documentation: - A few exported functions are now hidden, because they were only used internally in the library. - A few exported symbols were renamed to document them better than previously. - Cosmetic changes all along the way, as well as some fixes here and there. --HG-- extra : convert_revision : xtraeme%40gmail.com-20100121021019-onbsivlrhdb7t3ou
