-/**
- * TTemplate implements PRADO template parsing logic.
- * A TTemplate object represents a parsed PRADO control template.
- * It can instantiate the template as child controls of a specified control.
- * The template format is like HTML, with the following special tags introduced,
- * - component tags: a component tag represents the configuration of a component.
- * The tag name is in the format of com:ComponentType, where ComponentType is the component
- * class name. Component tags must be well-formed. Attributes of the component tag
- * are treated as either property initial values, event handler attachment, or regular
- * tag attributes.
- * - property tags: property tags are used to set large block of attribute values.
- * The property tag name is in the format of prop:AttributeName, where AttributeName
- * can be a property name, an event name or a regular tag attribute name.
- * - directive: directive specifies the property values for the template owner.
- * It is in the format of &lt;% property name-value pairs %&gt;
- * - expressions: expressions are shorthand of {@link TExpression} and {@link TStatements}
- * controls. They are in the formate of &lt;= PHP expression &gt; and &lt; PHP statements &gt;
- * - comments: There are two kinds of comments, regular HTML comments and special template comments.
- * The former is in the format of &lt;!-- comments --&gt;, which will be treated as text strings.
- * The latter is in the format of &lt;%* comments %&gt;, which will be stripped out.
- *
- * Tags other than the above are not required to be well-formed.
- *
- * A TTemplate object represents a parsed PRADO template. To instantiate the template
- * for a particular control, call {@link instantiateIn($control)}, which
- * will create and intialize all components specified in the template and
- * set their parent as the control.

-/**
- * TThemeManager class
- *
- * TThemeManager manages the themes used in a Prado application.
- *
- * Themes are stored under the directory specified by the
- * {@link setBasePath BasePath} property. The themes can be accessed
- * via URL {@link setBaseUrl BaseUrl}. Each theme is represented by a subdirectory
- * and all the files under that directory. The name of a theme is the name
- * of the corresponding subdirectory.
- * By default, the base path of all themes is a directory named "themes"
- * under the directory containing the application entry script.
- * To get a theme (normally you do not need to), call {@link getTheme}.
- *
- * TThemeManager may be configured within page service tag in application
- * configuration file as follows,
- * <module id="themes" type="System.Web.UI.TThemeManager"
- *         BasePath="Application.themes" BaseUrl="/themes" />
- * where {@link getCacheExpire CacheExpire}, {@link getCacheControl CacheControl}
- * and {@link getBufferOutput BufferOutput} are configurable properties of THttpResponse.
