Difference between the Introjucer and the Projucer

Hi.  I am new to Juce, and I am learning and going through the tutorials and everything is going great so far. I have a question that may seem rather simple. What is the difference between the introjucer and the projucer?  The main differece that I see is that the Introjucer lets you use the Graphic gui editor which is really helpful, and it said it is used for managing your cross platform code all in one build and one location. Any help for me to better understand, why I would use one instead of the other would be helpful.


The Projucer and the Introjucer are identical apart from the live coding environment in the projucer. The following video shows off the live coding environment:
