+
+<p><tt class="COMMAND">bzip2</tt>(1) is an alternative compression program installed on
+Slackware Linux. It uses a different compression algorithm from <tt
+class="COMMAND">gzip</tt>, which results in some advantages and some disadvantages. The
+main advantage for <tt class="COMMAND">bzip2</tt> is the compressed file size. <tt
+class="COMMAND">bzip2</tt> will almost always compress better than <tt
+class="COMMAND">gzip</tt>. In some instances, this can result in dramatically smaller
+files. This can be a great advantage for people on slower modem connections. Also
+remember, when downloading software from a public ftp server, it's generally good
+netiquette to download the <tt class="FILENAME">.bz2</tt> files instead of the <tt
+class="FILENAME">.gz</tt> files, as this results in less overhead for the generous people
+hosting the server.</p>
+
+<p>The disadvantage to <tt class="COMMAND">bzip2</tt> is that it is more CPU intensive
+than <tt class="COMMAND">gzip</tt>. This means that bzipping a file will generally take
+longer and will use more of the CPU than gzipping the file would. When considering which
+compression program to use, you must weigh this speed vs. compressed size and determine
+which is more important.</p>
+
+<p>The usage of <tt class="COMMAND">bzip2</tt> is nearly identical to <tt
+class="COMMAND">gzip</tt>, so not much time will be spent discussing it. Like <tt
+class="COMMAND">gunzip</tt>, <tt class="COMMAND">bunzip2</tt> is identical to <tt
+class="COMMAND">bzip2 -d</tt>. The primary difference in practical usage is that <tt
+class="COMMAND">bzip2</tt> uses the <tt class="FILENAME">.bz2</tt> extension.</p>
