I have thought about putting a large comment section into my perl script after the __END__ mark, and I am wondering if this is okay. How does perl parse the files? Does it read the entire script into memory FIRST even if it's over 1MB, or does it read pl files one buffer at a time and when it encounters the __END__ then it stops reading? If it reads the entire script into memory, then I guess it would be wiser for me to put the comments into a separate text file..
