<sect3><title>Program file descriptions</title>

<sect4><title>bunzip2</title>
<para>bunzip2 decompresses files that are compressed with
bzip2.</para></sect4>

<sect4><title>bzcat</title>
<para>bzcat (or bzip2 -dc) decompresses all specified files to the standard 
output.</para></sect4>

<sect4><title>bzcmp, bzdiff</title>
<para>bzcmp and bzdiff are used to invoke the cmp or the diff program on
bzip2 compressed files.</para></sect4>

<sect4><title>bzegrep, bzfgrep, bzgrep</title>
<para>bzegrep, bzfgrep, and bzgrep invoke either egrep, fgrep, or grep
(respectively) on bzip2-compressed files.</para></sect4>

<sect4><title>bzip2</title>
<para>bzip2 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 (such as the traditional <userinput>gzip</userinput> utility)
and approaches the performance of the PPM family of statistical
compressors.</para></sect4>

<sect4><title>bzip2recover</title>
<para>bzip2recover recovers data from damaged bzip2 files.</para></sect4>

<sect4><title>bzless</title>
<para>bzless is a filter which allows examination of compressed
or plain text files, one screenful at a time on a soft-copy
terminal, like less.</para></sect4>

<sect4><title>bzmore</title>
<para>bzmore is a filter which allows examination of compressed
or plain text files, one screenful at a time on a soft-copy
terminal, like more.</para></sect4>
