+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.

+Binlog checksum testing
+=======================
+
+1. How it works.
+The script copies a <suite> to directory <suite>_checksum, 
+collects test case names for t/ directory (except tests from
+disabled def), randomly choose 90% of tests and add them 
+to disabled.def.
+It means that mtr will run only 10% of random tests from each 
+suite.
+At end the script run mtr:
+./mysql-test-run.pl --suite=aaa_checksum,bbb_checksum \
+    --mysqld=--binlog-checksum=CRC32 arg1 ... argN
+
+aaa,bbb 	- suite names from --suite option
+arg1,argN	- other command-line arguments of checksum.pl
+
+2. The options:
+
+--suite=suite1,suite2.  Mandatory option. The list of suites for 
+    binlog checksum testing.
+
+--percent=N, where N is 1..99. Percent of running tests.
