+<CODE>bzip2</CODE> compresses files using the Burrows-Wheeler
+block-sorting text compression algorithm, and Huffman coding.
+Compression is generally considerably better than that
+achieved by more conventional LZ77/LZ78-based compressors,
+and approaches the performance of the PPM family of statistical compressors.

+<CODE>bzip2</CODE> is built on top of <CODE>libbzip2</CODE>, a flexible library
+for handling compressed data in the <CODE>bzip2</CODE> format. This manual
+describes both how to use the program and
+how to work with the library interface. Most of the
+manual is devoted to this library, not the program,
+which is good news if your interest is only in the program.

+Chapter 2 describes how to use <CODE>bzip2</CODE>; this is the only part
+you need to read if you just want to know how to operate the program.
+Chapter 3 describes the programming interfaces in detail, and
+Chapter 4 records some miscellaneous notes which I thought
+ought to be recorded somewhere.
