I'm new to RTC and Jazz Team Build, using RTC 3.0.

For a Command Line - JBE build definition, I would like to pass a variable for the userID of the user who requests the build. For example, in Build Forge, I have the built-in variable $BF_USER. I can't find anything in the RTC documentation for how to do this. Seems like it should be simple, RTC knows who is logged in, but I just can't figure it out. What am I missing?

Thanks for any suggestions.
