%description
These are tools for compressing, decompressing, printing, and searching bzip3
files. bzip3 features higher compression ratios and better performance than
bzip2 thanks to an order-0 context mixing entropy coder, a fast
Burrows-Wheeler transform code making use of suffix arrays and a run-length
encoding with Lempel-Ziv prediction pass based on LZ77-style string matching
and PPM-style context modeling.
