+// Feature checking in go-criu is based on the libcriu feature checking function.
+
+// Feature checking allows the user to check if CRIU supports
+// certain features. There are CRIU features which do not depend
+// on the version of CRIU but on kernel features or architecture.
+//
+// One example is memory tracking. Memory tracking can be disabled
+// in the kernel or there are architectures which do not support
+// it (aarch64 for example). By using the feature check a libcriu
+// user can easily query CRIU if a certain feature is available.
+//
+// The features which should be checked can be marked in the
+// structure 'struct criu_feature_check'. Each structure member
+// that is set to true will result in CRIU checking for the
+// availability of that feature in the current combination of
+// CRIU/kernel/architecture.
+//
+// Available features will be set to true when the function
+// returns successfully. Missing features will be set to false.
