23// The symbol vendor class is designed to abstract the process of searching for
24// debug information for a given module. Platforms can subclass this class and
25// provide extra ways to find debug information. Examples would be a subclass
26// that would allow for locating a stand alone debug file, parsing debug maps,
27// or runtime data in the object files. A symbol vendor can use multiple
28// sources (SymbolFile objects) to provide the information and only parse as
29// deep as needed in order to provide the information that is requested.
