Edit a file on an ISO

[Bart Silverstrim]

Is there a way or a howto/etc. that deals with how to edit a file on an 
ISO and re-burn easily?

I have a bootable iso image and on it there is a file I'd like to make a 
small edit on before burning to an actual CDR.  I know you can jumpt 
through a series of steps to extract the files and then move them to a 
new ISO image and burn that, but I was hoping there was an easier way to 
  do this since I just have a small change to make to one little file.

Thanks,
-Bart
