+
+  MySQL Slap
+
+  A simple program designed to work as if multiple clients querying the database,
+  then reporting the timing of each stage.
+
+  MySQL slap runs three stages:
+  1) Create Schema (single client)
+  2) Insert data (many clients)
+  3) Load test (many clients)
+  4) Cleanup (disconnection, drop table if specified, single client)
+
+Examples:
+
+Supply your own create, insert and query SQL statements, with 5 clients
+loading (10 inserts for each), 50 clients querying:
+
+./mysqlslap --create="CREATE TABLE A (a int)" --data="INSERT INTO A (23)" --iterations=200
+            --query="SELECT * FROM A" --number-rows=10 --concurrency=50 --load-concurrency=5
+
+Let the program build create, insert and query SQL statements with a table of
+two int columns, 3 varchar columns, with 5 clients loading data
+(12 inserts each), 5 clients querying, drop schema before creating:
+
+./mysqlslap --concurrency=5 --concurrency-load=5 --iterations=20 --number-int-cols=2 --number-char-cols=3 --number-rows=12 --auto-generate-sql
+
+Let the program build the query SQL statement with a table of
+two int columns, 3 varchar columns, 5 clients querying, don't
+create the table or insert the data (using the previous test's schema
+and data)
+
+./mysqlslap --concurrency=5 --iterations=20 --number-int-cols=2 --number-char-cols=3 --number-rows=12 --auto-generate-sql --skip-data-load --skip-create-schema
+
+Tell the program to load the create, insert and query SQL statements
+from the specified files which the create.sql file has multiple table creation
+statements delimited by ';', multiple insert statements delimited by ';',
+and multiple queries delimited by ';', run all the load statements with 5
+clients, 5 times per client, and run all the queries in the query file with
+5 clients:
+
+/mysqlslap --drop-schema --concurrency=5 --concurrency-load=5 --iterations=5 --query=query.sql --create=create.sql --data=insert.sql --delimiter=";" --number-rows=5
+
+Same as the last test run, with short options
+./mysqlslap -D -c 5 -l 5 -i 5 -q query.sql --create create.sql -d insert.sql -F ";" -n 5
