-Dear Mr. Bateman
-
-I apologize for not responding to this previously.
-
-The clarification we discussed is the following
-
-
-The clause in the license statement  that states
-
->>Written notification is provided to the developers of intent to use this 
->> software. Also, we ask that use of ARPACK is properly cited in any 
->> resulting publications or software documentation.
-
-has the following intension in your case.
-
-We are asking for acknowledgment in FEDORA that ARPACK is
-the software that underlies what corresponds to the  "eigs" command.   
-There is no intention to pass on a requirement of notification of use
-from users of FEDORA.   
-
-This is the understanding we have with MATLAB for example.
-
-If the above note or a slight modification of it is not acceptable
-for the purposes of using ARPACK in FEDORA, I will have to refer
-you to the tech transfer department of Rice University as I explained
-during our phone conversation.
-
-Once again my apologies for the delay and I thank you for your
-interest in ARPACK.
-
-Best Regards
-Dan Sorensen
