Filter Test Harness
For a more detailed description of the filter harness, either generate the documentation or read the harness.h file.
Running the program without arguments enters the interactive mode. Type 'help' for a list of all commands.
The default values for threads and sessions are stored in the 'harness.cnf' file
Mandatory parameters for the command line mode are -c and -i.
Parameters for the command line:
-h Display this information
-c Path to the MaxScale configuration file to parse for filters
-i Name of the input file for buffers
-o Name of the output file for results
-q Suppress printing to stdout
-t Number of threads
-s Number of sessions
-d Routing delay
