|
* The RCS service gives a write only interface to different services wanting to save changes to objects. |
14

15
|
|
|
* The RCS service will try to initialize the backend based on GNU RCS, but, if that fails, fall back |
16

|
|
* to the nullrcs handler. The nullrcs handler does not save anything at all. |

|
* <b>Configuration parameters that are in use by this service:</b> |
19
|
|
|
* * string midcom_services_rcs_bin_dir - the prefix for the rcs utilities (normally /usr/bin) |
20
|
|
|
* * string midcom_services_rcs_root - the directory where the rcs files get placed. |
21
|
|
|
* * boolean midcom_services_rcs_enable - if set, midcom will fail hard if the rcs service is not operational. |
