To create a launch configuration
When you hit Run the button, the compile will be launched. The output will appear in the console window. SVEditor will parse the output of the compile, and you will be able to double-click on any warnings or errors you find, which will take you to that location in the file.
After this initial setup, you will be able to hit "Run" button or hit Ctrl+F11 to re-run the launch.
