# Design Decisions # Design Decisions
- Code structure
App creates a race instance which can:
instantiate a file parser to extract race setting and team information;
creates and passes legs and teams/boats into event generator to create events;
runs a race and iterates all events that returned from the generator;
prints out event details, including time, involved boats and legs.
- Configuration file
We decided to store the team information including team names and boat velocity, as well as race configuration setting in external file.
To read external files, "Json-simple" library has been used to parse information.
By using this library, we did not have to write our json parser and benefited from the flexibility of json files.

# User Manual # User Manual
## Running the application
When you execute the application, it will try to load a configuration file called config.json located in doc/examples/.
You can specify a config file using the using the -f flag, for example 'java -jar app.jar -f doc/examples/config1.json'
## The config file
The teams/boats are specified in the config file under 'teams', each team requires a team name, and a velocity (in meters per second).
The 'time-scale' option lets you change how long the race takes to complete. A time-scale of 1.0 is normal speed, 2.0 is 2x etc.
The 'race-size' option lets you specify how many boats will be selected to compete in each race. There must be at least this many teams defined.
