The value of this option is a list containing cons-cells where the car is a function which is called to identify the VC-backend for a DIRECTORY and the cdr is a function which is called to check the VC-state of the FILEs contained in DIRECTORY. Identify-backend-function: It gets a full directory-name as argument - always without ending slash \(rsp. backslash for native Windows-XEmacs) - and has to return a unique symbol for the VC-backend which manages that directory \(e.g. 'CVS for the CVS-system or 'RCS for the RCS-system) or nil if the file is not managed by a version-control-system. Check-vc-state-function: It gets a full filename \(ie. incl. the complete directory-part) and has to return a symbol which indicates the VC-state of that file. The possible returned values of such a check-vc-state-function have to be mapped with `ecb-vc-state-mapping' to the allowed ECB-VC-state values.
