+Description
+    This boundary condition enforces a cyclic condition between a pair of
+    boundaries, whereby communication between the patches is performed using
+    an arbitrarily coupled mesh interface (ACMI) interpolation.
+
+    \heading Patch usage
+
+    Example of the boundary condition specification:
+    \verbatim
+    myPatch
+    {
+        type            cyclicACMI;
+    }
+    \endverbatim
