 # Usage:
 #
 #   PortGroup               mpi 1.0
+#
+# Available procedures:
+# proc mpi_active_variant_name {depspec}
+#   Returns the name of the active MPI variant of a dependency.
+# proc mpi_variant_name {}
+#   Returns the name of the active MPI variant of this port.
+# proc mpi.enforce_variant {args}
+#   Raise an error if the dependency does not have the same MPI variant
+#   as this port. Also enforces that the dependency has the same C variant.
+# proc mpi_variant_isset {}
+#   Whether an MPI variant has been set.
+# proc mpi.setup {args}
+#   Creates MPI variants.
+#   Available arguments: "require" means an MPI variant must be set. "-mpich", "-openmpi", etc.
+#   means remove this variant from the list. All of the arguments for compilers.setup are available
+#   too and will be passed to that procedure. "default" means an MPI variant (mpich) will be
+#   set as a default variant.
