+Putting testcases here
+~~~~~~~~~~~~~~~~~~~~~~
+
+When you work on re-verifying or re-classifying a bug (not fixing it),
+it's a good idea to put the mtr-parsable '.test' testcase here.
+Benefits:
+1) tests downloaded from the bugs db are sometimes close to
+mtr-parsable but not completely (for example if they contain
+/* comment */); when you re-verify or re-classify you run the test so
+may have to make it mtr-parsable; if you then put it in this suite,
+the developer who will work on this bug in a few weeks or months will
+not have to re-do the same download&fix, she/he can instead reuse your
+work.
+2) Others can see how their own work influences many unsolved
+bugs, by running this suite. If they find that they fix a bug in this
+suite, we won't later wonder "how come this bug doesn't happen
+anymore, what fixed it?".
+3) One can also run this suite with certain switches to see how they
+influence unsolved bugs:
+./mtr --suite=optimizer_unfixed_bugs \
+--mysqld=--optimizer_switch="firstmatch=off"
+
+Adding tests to this suite
+~~~~~~~~~~~~~~~~~~~~~~~~~~
+One test file per bug, named bugNNNNN.test.
+Put the correct (not current and buggy) result file in r/, so that "[ pass ]"
+in mtr will mean that a bug looks like fixed.
+When you have fixed a bug, remove files from this suite.
+t/bug45219.test is an example.
