+ * FastLZ (MIT license) is an ANSI C/C90 implementation of Lempel-Ziv 77 
+ * algorithm (LZ77) of lossless data compression. It is suitable to compress 
+ * series of text/paragraphs, sequences of raw pixel data, or any other blocks 
+ * of data with lots of repetition. It is not intended to be used on images, 
+ * videos, and other formats of data typically already in an optimal 
+ * compressed form.
