# This will give all the ICSE2015/2016 papers filenames extracted from the titles of the PDF metadata, 
# and put them in a folder on your desktop. It's been tested on OSX and depends on wget and pdfinfo, 
# available via the macports xpdf package on pre-Yosemite OSX, and here for Yosemite users:
#
#    ftp://ftp.foolabs.com/pub/xpdf/xpdfbin-mac-3.04.tar.gz
#
# It's a manual install, unfortunately, but I trust you're geared up for that.
#
# The username and password are available from these public-facing pdfs: 
#    http://atlantis.isti.cnr.it/ICSE2015ProgramBrochureOnLineVersion.pdf  (2015 - icse15/conf15)
#    http://2016.icse.cs.txstate.edu/static/downloads/conference-brochure.pdf  (2016 - icse16/conf16)
# The "grep [ab]" part is what filters out the papers from schedules, posters and other PDFs, which 
# may or may not have Title metadata. Because someone thought "we'll use the fifth character in the 
# filename as meaningful metadata. That is entirely sane and reasonable."
# 
# This script was first written in 2015, and has been updated for ICSE 2016 mostly by replacing all 
# instances of "15" with "16".
#
# I wish I was joking.

wget -c --user=icse16 --password=conf16 http://conferences.computer.org/icse/2016/content/icsefull.zip  && unzip -d icsefull icsefull.zip
cd icsefull/content/papers/
mkdir sanity && cd sanity
for x in `ls ../*.pdf | grep [ab]`; do cp $x "`pdfinfo -meta $x | grep "^Title:" | sed 's/Title:          //' | sed 's/\//-/g'`.pdf" ; done
cd .. && mv sanity ~/Desktop/ICSE2016

Here's an alternative which..:

1. adds a dependency on fuse-zip so the archive never needs to be decompressed (except when actually reading a PDF from within it), avoiding the file size tripling of the original (zip + decompressed + cp'd);
2. adds a few sanity checks;
3. roughly triples the script size (well, you can't hug all the cats)
