cNBT is an NBT File (http://www.minecraft.net/docs/NBT.txt) parser that doesn't
depend on the horrible slowdown that is the JRE and sticks to the C principle of
not trying to prevent users to shoot their own feet.

Currently implemented features:

 * Complete parsing of NBT files
 * Basic tree-manipulation functions
 * Pretty printing with indentation
 * Writing (possibly modified) NBT structures back to a compressed file
 * Full error reporting and graceful recovery from corrupt files and trees.

It depends on libz for gzip decompressing and compressing, and compiler C99
support.
