script question, detect if inside X

How can I detect if a script is executed in a X environment or outside?
Thanks

Re: script question, detect if inside X

As in you want the script to know whether it is in X or not?  Or you want a separate program to check if a script was started in X?

For the first, I reckon just checking to see if DISPLAY is set is enough.
For the second, I have no idea.
