The Unity3d globalArgLine. Allows you to define a per default global configuration for all your unity3d builds.

Combined with a plugin like EnvInject, allows you to configure most of your projects in one place.

For example: use:

-logFile "$WORKSPACE/unity3d_editor.log" -quit -batchmode -executeMethod $UNITY_EXECUTEMETHOD $UNITY_EXTRA_ARGUMENTS

and define per project the UNITY_EXECUTEMETHOD and optional UNITY_EXTRA_ARGUMENTS variables.

Is overriden by the per project argLine value.
