Hi Peter,

Nice.

I was now able to get the Freecell Solver test suite to pass with "ninja test",
but there is one problem: when I run "ninja -vv test", then ninja displays the
line 
"[1/1] cd /home/shlomif/progs/freecell/git/fc-solve/fc-solve/source/n &&
perl /home/shlomif/progs/freecell/git/fc-solve/fc-solve/source/run-tests.pl"

and then it waits for the entire test suite to run, and only then displays its
output. This is frustrating because I want to see the output while the test
suite is running. Is there anyway to do it like that?
