tasks is a list of tasks to execute from the build file,
ver is the .NET Framework version to target - 1.0, 1.1, 2.0, 3.0, or 3.5 (default)
debug dumps information on the properties, includes, and tasks, as well as more detailed error information.
timing prints a report showing how long each task took to execute
docs prints a list of available tasks
