Detailed Description

Contains compressors and encoders that work with Lempel-Ziv-Welch-like dictionaries.

The LZW family works with bottom-up dictionaries containing indexed entries to achieve compression. Other than lz78, the dictionary entries do not explicitly store the follow-up symbol. Instead, they are re-generated on the fly by the decoder.
