Many services on Mac OS X, such as image compression/decompression, audio format conversion, file import/export and so on are provided by components. Components are a type of shared library that you can manipulate using the Component Manager. The Component Manager registers these shared libraries by looking for a component resource (a resource of type 'thng') in a specific component file.

Given a particular component type, the Component Manager can locate and query all components of that type. You can find out how many components of a specific type are available and you can get further details about a component's capabilities.

Fiendishthngs lists all the Components it finds on the system and lets you query them for information.
