Detect if a configuratil file was changed
Jiri Srain <jsrain@suse.cz> Support routines for detecting changes of configuration files being done externally <not by YaST> to prevent the changes from being lost because of YaST not handling the configuration files correctly (eg. removing comments in some cases, changing order of options,...) Warns user if such change is detected. Usage: Before reading the configuration file: call boolean CheckFiles <list>) with all files. If any of them is detected to be changed, YaST asks a popup for you. alternatively use boolean FileChanged <string> for each file (does not ask any question, immediatelly returns status of the file After writing the configuraiton file: call void StoreFileCheckSum <string> for each file to store recent checksum. YaST will use this checksum next time checking.
This module has an unstable interface.
