Jeff and I have worked out a list of items we need to discuss for next  
week.  The goal is to finalize things so that we can begin to put the  
API down in LaTex documents.  Some of this issues are pretty much  
resolved but we should go over them one more time.

1. Use of intent(IN/OUT/INOUT) for parameters.

These requires careful thought in some circumstances.  For example,  
should the Send/Recv and Isend/Irecv data buffers all be INOUT to keep  
the compiler for doing surprising things?

2. Review of new MPI derived types to be used, for example,  

3. How to handle MPI attributes and extra state variables.  This can  
be done in a very Fortran way as it doesn't have to look the MPI C.

4. What should the name of the new module be.  We had discussed not  
changing the name, i.e.,

      USE MPI

However, users will have to explicitly change their code to use the  
new module so I don't see how we can get away with using the old  
module name.

5. Review what integer kind should be used for things like tags.   
We've previously decided to use default integer kinds except for  
possibly for counts, in which case we would specify a specific kind,  

Any other issues?  Please let me know and I'll add it to the agenda.
