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.
