                                              throws JasperException
        Parses the tag file, and collects information on the directives included in it. The method is used to obtain the info on the tag file, when the handler that it represents is referenced. The tag file is not compiled here.
        Parameters:
        pc - the current ParserController used in this compilation
        name - the tag name as specified in the TLD
        path - the path for the tagfile
        jar - the Jar resource containing the tag file
        tagLibInfo - the TagLibraryInfo object associated with this TagInfo
        Returns:
        a TagInfo object assembled from the directives in the tag file.
        Throws:
        JasperException - If an error occurs during parsing

                          throws JasperException
        Implements a phase of the translation that compiles (if necessary) the tag files used in a JSP files. The directives in the tag files are assumed to have been processed and encapsulated as TagFileInfo in the CustomTag nodes.
        Parameters:
        compiler - Compiler to use to compile tag files
        page - The page from to scan for tag files to compile
        Throws:
        JasperException - If an error occurs during the scan or compilation
