iwnbtjl
A Java NBT library with freedom.
The Ian Watters Named Binary Tag Java Library (IWNBTJL for short) is a Java library that allows work with the Named Binary Tag format created by Notch with any project of your's (please note, no one owns NBT). Written off of the JNBT library (http://jnbt.sourceforge.net/), this contains usage improvements, however is not too different from the original library.
