Comment:
I have just been through the spkg, and added a SPKG.txt and a minimal
testsuite. If someone can double check them, this is good to go I guess.
Jean-Pierre: would you be so kind as to try the spkg under cygwin to see
how it goes? Not that we really need it now, but that could catch other
platform issues. A second eye on the SPKG won't hurt as well.
Thanks!
Nicolas
