[PRad] PRad2-X17-DRad weekly meeting this Friday

[gasparan]

  Hi Eugene,

  You are right about that but, I did not forget that very important item 
for discussion.
  The point is that this item is done on the collaboration level and it 
needs to be discussed
  with the Engineering group.
  I will send an email now to Bob about that meeting (with cc's to 
related people).

  Thanks,
  Ashot
