The component update URL which should point to a text file containing one or two rows (separated by \r\n or \n): 1. A list of increasing versions separated by pipes, such as "1.0.0|1.0.1|1.0.2" (without quotes) 2. (optional) The absolute HTTP URL of the latest DLL, for example "http://www.server.com/update/MyAssembly.dll" (without quotes) The second row should only be present if the provider can be updated automatically without any type of user intervention, i.e. by simply replacing the DLL and restarting the wiki. If the DLL contains multiple providers, they are all updated (obviously). The new DLL must have the same name of the being-replaced DLL (in other words, a provider must reside in the same DLL forever in order to be updated automatically).
