[CIG-SEISMO] Source time function in SPECFEM3D

[Dimitri Komatitsch]

Dear Fatimah,

This is good timing, that topic has been discussed this week between 
developers and decisions have been made (they did not cc the mailing 
list because the discussion was a bit technical). I will forward you 
their email in a few minutes. Feel free to contact them and cc me.

Best regards,
Dimitri.
