Open in CoCalcHECKE on SPARC Ultra, caveats:
  1. Because of the libraries involved, people would see *MUCH* better performance if they recompiled their own versions of hecke (or at least had a dynamically linked version which would use their native libs). My statically linked version is probably the lowest common denominator of the post-sparc2 era -- very primitive.
  2. Note I have done *zero* testing on this, other than the help system...:)
