'''SPIRES script
Usage:
python spires.py reference [ -hbiatcev ] [ --help ] [ --library library.bib ] [ --download download_path/ ]
"reference" must be a standard arXiv reference, e.g. hep-th/9711200, 0705.0303, Maldacena:1997re or a SPIRES journal reference, e.g. CMPHA,43,199
Options:
-h, --help
displays this help message
-b
displays the BiBTeX entry
-i
displays the bibitem entry
-a
displays the author(s)
-t
displays the title
-c
displays the TeX citation key
-e
displays everything
-v
verbose mode

--download download_path/
for arXiv references downloads a pdf of the paper from the arXiv to the directory download_path/
--library library.bib
if it is not already in library.bib, appends the BiBTeX entry to library.bib; use at your own risk
