+This directory contains several tests to the GRAS mecanism. The
+difference with the examples/gras directory is that what's in here
+tests some corner case that nobody would try in the first place. Here
+is a list of the directory content:
+
+datadesc/ Tests the marshalling facilities, trying to read messages
+ comming from all the known architectures. This is done by
+ storing these messages in files and loading them as if they
+ were comming from a socket.
+
+empty_main/ Once upon a time, GRAS was broken when processes did
+ nothing. This test is here to ensure that this never
+ happen again.
+
+msg_handle/ Ensures the wanted semantic for gras_msg_handle(i) when
+ i<0, i==0 and i>0.
