I'm with Xriley it doesn't make a lot of sense to either-

I think the original script was trying to use a here doc - that's the only valid use of <<
example:
Code:
# feeding answers to a program's stdin that asks three questions:
./myprogram <<BAR
answer1
answer2
answer3
BAR

"BAR" delimits the end of the here doc. That's my take on it anyway.
