Download nips25offline??

What is the meaning here, I opened a page, what needs to be download ？
and run in getabstracts.py
$$$
f = open("abstracts/a%d.txt" % (int(paperid), ) ,"w")
$$$
I can't get a%d.txt
When I changed f to f = open("abstracts/a%s.txt" % (paperid, ) ,"w"),I get lots of a%s.txt
Can I do that correctly?

Start by reading getabstracts.py and the code around the abstracts/a%d.txt open call. Reproduce the filename behavior with the paperid value, then determine the intended output naming and verify that generated files are written under abstracts/. The issue does not name a test or provide a clear expected result.
