DatLib is now at the heart of all of my tools!

It supports a variety of data file formats and handles the standard loading, cleansing, converting and saving operations that are required by tools such as DatUtil, MAMEDiff, ROMBuild, ROMInfo and ZipIdent.

This package is a source only release and is only required if you want to compile any of my tools.
