  First, consider the verbose/quiet example. If we want //Horde_Argv//  
to set verbose to TRUE unless "-q" is seen, then we can do this:

  <code type="php">
-$parser->addOption('-v', array('action' => 'store_true', 'dest' =>  
'verbose', $default => true));
+$parser->addOption('-v', array('action' => 'store_true', 'dest' =>  
'verbose', 'default' => true));
  $parser->addOption('-q', array('action' => 'store_false', 'dest' =>  
'verbose'));
  </code>

  Oddly enough, this is exactly equivalent:

  <code type="php">
  $parser->addOption('-v', array('action' => 'store_true', 'dest' =>  
'verbose'));
-$parser->addOption('-q', array('action' => 'store_false', 'dest' =>  
'verbose', $default => true));
+$parser->addOption('-q', array('action' => 'store_false', 'dest' =>  
'verbose', 'default' => true));
  </code>

  Those are equivalent because you're supplying a default value for  
the option's destination, and these two options happen to have the  
same destination (the verbose variable).

  Consider this:

  <code type="php">
-$parser->addOption('-v', array('action' => 'store_true', 'dest' =>  
'verbose', $default => false));
-$parser->addOption('-q', array('action' => 'store_false', 'dest' =>  
'verbose', $default => true));
+$parser->addOption('-v', array('action' => 'store_true', 'dest' =>  
'verbose', 'default' => false));
+$parser->addOption('-q', array('action' => 'store_false', 'dest' =>  
'verbose', 'default' => true));
  </code>

  Again, the default value for verbose will be TRUE: the last default  
value supplied for any particular destination attribute is the one  
that counts.
