   <para>   
   The package vendor list contains a list of all vendors
   from whom you wish to  authenticate  downloaded  packages.
   For each vendor listed, it must contain the corresponding
   PGP key fingerprint, so that  APT  can  perform  signature
   verification  of the release file and subsequent checking
   of the checksums of each  downloaded  package.
   To have authentication enabled, you must add the 
   vendor identification string  (see  below) enclosed in
   square braces to the sources.list line for all sites that mirror
   the repository provided by that vendor.
   <para>
   The format of this file is similar  to  the  one  used  by
   apt.conf.  It consists of an arbitrary number of blocks of
   vendors, where each block starts with a string telling the
   <replaceable/key_type/ and the <replaceable/vendor_id/.
   <para>
   Some vendors may have multiple blocks that define different
   security policies for their distributions. Debian for instance
   uses a different signing methodology for stable and unstable releases.
   <para>
   <replaceable/key_type/ is the type of the check required.
   Currently, there is only one type available which is 
   <literal/simple-key/.
   <para>
   <replaceable/vendor_id/ is the vendor identification string. It is an
   arbitrary string you must supply to uniquely identifify a
   vendor that's listed in this file.
   
   Example:
<informalexample><programlisting>   
simple-key "joe"
{
   Fingerprint "0987AB4378FSD872343298787ACC";
   Name "Joe Shmoe &lt;joe@shmoe.com&gt;";
}						    
</programlisting></informalexample>

 <RefSect1><Title>The simple-key type</>
   <para>   
   This type of verification is used when the vendor has a single
   secured key that must be used to sign the Release file. The
   following items should be present
   
   <VariableList>
     <VarListEntry><Term>Fingerprint</Term>
     <ListItem><Para>
     The PGP fingerprint for the key. The fingerprint should be
     expressed in the standard notion with or without spaces.
     The <option/--fingerprint/ option for 
     <CiteRefEntry><RefEntryTitle><command/gpg/</RefEntryTitle><ManVolNum/1/</CiteRefEntry>
     will show the fingerprint for the selected keys(s).
     </VarListEntry>
     
     <VarListEntry><Term>Name</Term>
     <ListItem><Para>
     A string containing a description of the owner of
     the  key  or vendor.  You may put the vendor name and it's
     email. The string must be quoted with ".
     </VarListEntry>
     
   </VariableList>
