 <refsect1><title>Description</title>
   <para><command>apt-cdrom</command> is used to add a new CD-ROM to APT's list
    of available sources. <command>apt-cdrom</command> takes care of
   determining the structure of
   the disc as well as correcting for several possible mis-burns and 
   verifying the index files.   
   </para>

   <para>It is necessary to use <command>apt-cdrom</command> to add CDs to the
   APT system;
   it cannot be done by hand. Furthermore each disc in a multi-CD set must be
   inserted and scanned separately to account for possible mis-burns.
   </para>

   <para>Unless the <option>-h</option>, or <option>--help</option> option is
   given, one of the commands below must be present.</para>

    <variablelist>
     <varlistentry><term><option>add</option></term>
     <listitem><para><literal>add</literal> is used to add a new disc to the
     source list. It will unmount the
     CD-ROM device, prompt for a disc to be inserted and then proceed to 
     scan it and copy the index files. If the disc does not have a proper
     <filename>.disk</filename> directory you will be prompted for a descriptive 
     title.
     </para>

     <para>APT uses a CD-ROM ID to track which disc is currently in the drive and
     maintains a database of these IDs in
