Very basic noob question about class fundamentals
I'm looking at this line of code:
import flash.display.MovieClip;
and realized that I haven't seen yet anything else used instead of the word flash. in such lines. This made me wonder what it means. Is there other possible alternatives?. If yes, what could it be? If no, why this has to be included all the time when it is obviously the only choice?
Sorry for the noobish question but if it takes a quick explanation I will really appreciate it.
Thank you.
