+This script is intended to convert SMPI time independent traces (TIT) from the
+old format (simgrid version <= 3.19) to the new format.
+
+On the previous format each MPI_wait calls were associated to the last ISend of
+IRecv call arbitrarily.
+
+This new that includes tags field that links MPI_wait calls to the
+MPI_ISend or MPI_IRecv associated to this wait.
+
+This script reproduce the old behavior of simgrid because informations are
+missing to add the tags properly. It also lower case all the mpi calls.
+
+It takes in input (as argument or in stdin) the trace list file that is only a
+simple text file that contains path of actual TIT files split by rank.
+
+It creates a directory to put the traces on ("converted_traces" by default)
