/**
 * Subversion Propset command manager class
 *
 * Set PROPNAME to PROPVAL on files, dirs, or revisions.
 *
 * Note: svn recognizes the following special versioned properties
 * but will store any arbitrary properties set:
 *   svn:ignore     - A newline separated list of file patterns to ignore.
 *   svn:keywords   - Keywords to be expanded.  Valid keywords are:
 *     URL, HeadURL             - The URL for the head version of the object.
 *     Author, LastChangedBy    - The last person to modify the file.
 *     Date, LastChangedDate    - The date/time the object was last modified.
 *     Rev, LastChangedRevision - The last revision the object changed.
 *     Id                       - A compressed summary of the previous
 *                                  4 keywords.
 *   svn:executable - If present, make the file executable. This
 *     property cannot be set on a directory.  A non-recursive attempt
 *     will fail, and a recursive attempt will set the property only
 *     on the file children of the directory.
 *   svn:eol-style  - One of 'native', 'LF', 'CR', 'CRLF'.
 *   svn:mime-type  - The mimetype of the file.  Used to determine
 *     whether to merge the file, and how to serve it from Apache.
 *     A mimetype beginning with 'text/' (or an absent mimetype) is
 *     treated as text.  Anything else is treated as binary.
 *   svn:externals  - A newline separated list of module specifiers,
 *     each of which consists of a relative directory path, optional
 *     revision flags, and an URL.  For example
 *       foo             http://example.com/repos/zig
 *       foo/bar -r 1234 http://example.com/repos/zag
 *
 *
 * $switches is an array containing one or more command line options
 * defined by the following associative keys:
 *
 * <code>
 *
 * $switches = array(
 *  'F [file]'      =>  'Read data from specified file',
 *                      // either 'F' or 'file' may be used
 *  'q [quiet]'     =>  true|false,
 *                      // print as little as possible
 *  'R'             =>  true|false,
 *                      // descend recursively
 *  'recursive'     =>  true|false,
 *                      // descend recursively
 *  'revprop'       =>  true|false,
 *                      // operate on a revision property (use with r)
 *  'targets'       =>  'ARG',
 *                      // pass contents of file ARG as additional args
 *  'r [revision]'  =>  'ARG (some commands also take ARG1:ARG2 range)
 *                        A revision argument can be one of:
 *                           NUMBER       revision number
 *                           "{" DATE "}" revision at start of the date
 *                           "HEAD"       latest in repository
 *                           "BASE"       base rev of item's working copy
 *                           "COMMITTED"  last commit at or before BASE
 *                           "PREV"       revision just before COMMITTED',
 *                      // either 'r' or 'revision' may be used
 *  'username'      =>  'Subversion repository login',
 *  'password'      =>  'Subversion repository password',
 *  'no-auth-cache' =>  true|false,
 *                      // Do not cache authentication tokens
 *  'encoding'      =>  'ARG',
 *                      // treat value as being in charset encoding ARG
 *  'force'         =>  true|false,
 *                      // force operation to run
 *  'config-dir'    =>  'Path to a Subversion configuration directory'
 * );
 *
 * </code>
 *
 * Note: Subversion does not offer an XML output option for this subcommand
 *
 * The non-interactive option available on the command-line 
 * svn client may also be set (true|false), but it is set to true by default.
 *
 * 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('propset'), $options);
 *
 * // Define any switches and aguments we may need
 * $switches = array('username' => 'user', 'password' => 'pass');
 * $args = array('svn:mime-type', 'image/jpeg', 'foo.jpg');
 *
 * // Run command
 * if ($output = $svn->propset->run($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'];
 *         }
 *     }
 * }
 * ?>
