<title>Introduction to <application>UnZip</application></title>

<para>The <application>UnZip</application> package contains 
<filename>ZIP</filename> extraction utilities. These are useful for extracting 
files from <filename>ZIP</filename> archives. <filename>ZIP</filename> archives 
are created with <application>PKZIP</application> or 
<application>Info-ZIP</application> utilities primarily in a 
<acronym>DOS</acronym> environment.

<para>Install <application>UnZip</application> by running the following
commands:</para>

<screen><userinput><command>patch -Np1 -i ../unzip-&unzip-version;-fix_Makefile-1.patch &amp;&amp;
patch -Np1 -i ../unzip-&unzip-version;-fix_libz-1.patch &amp;&amp;

<title>Command explanations</title>

<para><command>make prefix=/usr LOCAL_UNZIP=-DUSE_UNSHRINK linux</command>:
This command overrides the <varname>prefix</varname> variable that is
set to <filename class="directory">/usr/local</filename> in the
<filename>Makefile</filename>, sets the <envar>LOCAL_UNZIP</envar>
environment variable to instruct <application>UnZip</application> to use
the shrinking algorithm based on the <acronym>LZW</acronym> compression
algorithm, and builds the executables for a Linux system.
The alternatives to 'linux' can be seen with a
<command>make list</command> command.</para>

<para><command>make ... linux_shlibz</command>: Build shared
<filename>libunzip</filename> and link <application>UnZip</application> against 
it and <application>zlib</application>.</para>
