Episode 151, where we talked about Oracle toolsmysqldbcompare and mysqldiff
Options discussed:
--replicate, --no-create-replicate-table
--no-check-binlog-format
--recurse (default is infinite), --recursion-method
--no-replicate-check, --quiet
--retries, --resume, --run-time
--set-vars
--no-empty-replicate-table
--max-lag, --check-slave-lag
--max-load (default: threads_running=25)
--pid
--no-check-plan
--no-check-replication-filters
--no-check-slave-tables

You can also give a comma-separated list of configuration files to read in, with the --config option. If you use it, the --config option has to be the first option on the commandline. The documentation says to look at the output using --help to see the default configuration files, and in the testing we did, this looked at:
/etc/percona-toolkit/percona-toolkit.conf
/etc/percona-toolkit/pt-table-checksum.conf
/root/.percona-toolkit.conf
/root/.pt-table-checksum.conf

--databases, --tables, --engines, --databases-regex, --tables-regex, --columns, --where
--ignore-databases, --ignore-tables, --ignore-engines (FEDERATED,MERGE by default), --ignore-columns, --ignore-databases-regex, --ignore-tables-regex
--chunk-time, --chunk-size, --chunk-index, --chunk-size-limit
--progress
--function (default is CRC32)
--float-precision
--explain
--replicate-check-only
--trim
--replicate-database
