+    The "coarray" dialect is designed to contain the basic coarray operations
+    in Fortran as descibed in the standard.
+    This includes synchronization operations, atomic operations,
+    image queries, teams, criticals, etc. The Coarray dialect operations use 
+    the FIR types and are tightly coupled with FIR and HLFIR.
