-/**
- * TUserManager class
- *
- * TUserManager manages a static list of users {@link TUser}.
- * The user information is specified via module configuration using the following XML syntax,
- * <code>
- * <module id="users" class="System.Security.TUserManager" PasswordMode="Clear">
- * <user name="Joe" password="demo" />
- * <user name="John" password="demo" />
- * <role name="Administrator" users="John" />
- * <role name="Writer" users="Joe,John" />
- * </module>
- * </code>
- *
- * PHP configuration style:
- * <code>
- * array(
- * 'users' => array(
- * 'class' => 'System.Security.TUserManager',
- * 'properties' => array(
- * 'PasswordMode' => 'Clear',
- * ),
- * 'users' => array(
- * array('name'=>'Joe','password'=>'demo'),
- * array('name'=>'John','password'=>'demo'),
- * ),
- * 'roles' => array(
- * array('name'=>'Administrator','users'=>'John'),
- * array('name'=>'Writer','users'=>'Joe,John'),
- * ),
- * ),
- * )
- * </code>
- *
- * In addition, user information can also be loaded from an external file
- * specified by {@link setUserFile UserFile} property. Note, the property
- * only accepts a file path in namespace format. The user file format is
- * similar to the above sample.
- *
- * The user passwords may be specified as clear text, SH1 or MD5 hashed by setting
- * {@link setPasswordMode PasswordMode} as <b>Clear</b>, <b>SHA1</b> or <b>MD5</b>.
- * The default name for a guest user is <b>Guest</b>. It may be changed
- * by setting {@link setGuestName GuestName} property.
- *
- * TUserManager may be used together with {@link TAuthManager} which manages
- * how users are authenticated and authorized in a Prado application.
