  8:     PetscViewerSAWsOpen - Opens an SAWs PetscViewer.

 10:     Collective on MPI_Comm

 12:     Input Parameters:
 13: .   comm - the MPI communicator

 15:     Output Parameter:
 16: .   lab - the PetscViewer

 18:     Options Database Keys:
 19: +   -ams_port <port number> - port number where you are running SAWs client
 20: .   -xxx_view ams - publish the object xxx
 21: -   -xxx_saws_block - blocks the program at the end of a critical point (for KSP and SNES it is the end of a solve) until
 22:                     the user unblocks the the problem with an external tool that access the object with the AMS

 24:     Level: advanced

 26:     Fortran Note:
 27:     This routine is not supported in Fortran.


 30:     Notes:
 31:     Unlike other viewers that only access the object being viewed on the call to XXXView(object,viewer) the SAWs viewer allows
 32:     one to view the object asynchronously as the program continues to run. One can remove SAWs access to the object with a call to
 33:     PetscObjectSAWsViewOff().

 35:     Information about the SAWs is available via http://bitbucket.org/saws/saws

 58:    Input Parameters:
 59: +  obj - the Petsc variable
 60:          Thus must be cast with a (PetscObject), for example,
