Oh, I don't recall right now (searching logs ...), but I think I just
faked the values in `tuning.c` (generated by `tune/tune[.c]`) by modifying
`test/test.c` (i.e., added something like `{ int i; for (i=2;i<=64;i++)
tuning_info[i].mul_fft_thresh=1; }` to the beginning of `test/test.c`(?)'s
`main()`).
After running `sage -f -s zn_poly`, start a Sage subshell and enter the
build directory.
Then you can play with it, i.e., modify the code (or tuning values), and
run `make test && test/test [-quick] [tests_to_run]*` (in
`$SAGE_ROOT/spkg/build/zn_poly-0.9.p{9,10}/src/`) IIRC.
(More to come if I find the logs, otherwise also see the comments above
for more info.)
