+
+  unfortunately there is some typo here: M5 uses GROVE for their connections
+  but we have GROOVE here.
+  But to maintain compatibility to older build commands we keep the (wrong) wording
+
+  This file contains M5 grove definitions.
+  They will be expanded to match the supported groves
+
+  Each definition must start with a line start starts with  #GROVE
+  Afterwards you can use normal C header style
+  $GS$ will be replaced with a grove suffix with _ (empty for first)
+  $G$ will be replaced by the simple grove name (empty for base)
+  $Z$ will be replaced by the simple name using "Z" for the first grove
