<para><command>bzip2</command> is a compression program.</para>

<para>The bzip2 KIO worker is not directly usable, and is intended for use
as a filter.  For example, the tar KIO worker can filter a file through
the bzip2 KIO worker, in order to display the contents of a <literal
role="extension">tar.bz2</literal> file directly in a &konqueror;
window.</para>

<para>If you click on a file compressed with a <literal
role="extension">.bz2</literal> in &konqueror;, this KIO worker is used to
uncompress it and display it as a normal (uncompressed) file.</para>

<para>If you are a developer, and would like to use the bzip2 filter,
you can find documentation on using KIO workers at <ulink
url="http://techbase.kde.org">http://techbase.kde.org</ulink></para>

<para> See the manual: <ulink url="man:/bzip2">bzip2</ulink>.
</para>

<para><command>bzip</command> is the ancestor of bzip2.  It is rarely
used today, having been replaced with bzip2, which offers much better
compression.</para>
