/**

 * Subversion Info command manager class

 *

 * Display information about a file or directory in PATH.

 *

 * If the 'path' option is omitted, '.' is assumed.

 *

 * $switches is an array containing one or more command line options

 * defined by the following associative keys:

 *

 * <code>

 *

 * $switches = array(

 *  'targets'       =>  'ARG',

 *                      // passes contents of file ARG as additional arguments

 *  'R'             =>  true|false,

 *                      // descend recursively

 *  'recursive'     =>  true|false,

 *                      // descend recursively

 *  'config-dir'    =>  'Path to a Subversion configuration directory',

 *

 *  'username'      =>  'username for accessing repository',

 *

 *  'password'      =>  'password for accessing repository'

 * );

 *

 * </code>

 *

 * Usage example:

 * <code>

 * <?php

 * require_once 'VersionControl/SVN.php';

 *

 * // Setup error handling -- always a good idea!

 * $svnstack = &PEAR_ErrorStack::singleton('VersionControl_SVN');

 *

 * // Set up runtime options. Will be passed to all

 * // subclasses.

 * $options = array('fetchmode' => VERSIONCONTROL_SVN_FETCHMODE_RAW);

 *

 * // Pass array of subcommands we need to factory

 * $svn = VersionControl_SVN::factory(array('info'), $options);

 *

 * // Define any switches and aguments we may need

 * $switches = array('R' => true);

 * $args = array('/path/to/working_copy');

 *

 * // Run command

 * if ($output = $svn->info->run($args, $switches)) {

 *     print_r($output);

 * } else {

 *     if (count($errs = $svnstack->getErrors())) {

 *         foreach ($errs as $err) {

 *             echo '<br />'.$err['message']."<br />\n";

 *             echo "Command used: " . $err['params']['cmd'];

 *         }

 *     }

 * }

 * ?>
