Note that +there are still parts that need to be coded, and that MNG support is around +90-95% (JNG at 100%). It is however compliant with the latest and greatest +MNG 1.0 specification. + +I hope to dedicate a bit more time this year to finish up full support and fill +in the remaining blanks.

The number of changes in the MNG specification have +resulted in a lot of new code and some changed code.
