Any application using the SDK is not yet able to set Tcl preferences. That implies that the applications when they ask for Tcl service can only use the global tcl preferences. We will have to fix this shortcoming in some future enhancements to the SDK.
In the meanwhile, iTest will use the first Tcl shell in the "PATH" for Tcl service for creating a tcl service by default and that should cover all the requirements (e.g. user can create a shell script which sets the PATH to appropriate tcl shell to be first in the PATH and then launch iTest after that in the script).
