This tool runs all spectests,
except those that
make spectest runs (that means all tests of which we don't know yet if they will pass or not).
For each file that passes at least one test (criterion might change in future) it prints out a short summary about the status of this file.
This is primarily used to identify tests that could be added to t/spectest.data, and those that are worth a closer look. But please don't add them blindly just because they all pass - chances are that there's a good reason for them not already being included.
This script should be called from the main Rakudo directory.
