# == Synopsis 
#   This program tries to download a PDF file for the given comma-separated pubmed IDs
#
# == Required GEMS
#     mechanize (0.9.3)
#     socksify (1.1.0) (if you plan on using SOCKS)
#
# == Examples
#     pubmedid2pdf.rb 19508715,18677110,19450510,19450585
#
#   Other examples:
#    This example downloads through SOCKS, here we are using a localhost connection through port 9999
#    Meaning that you can ssh to your some server you have access to that can access some PDFs that you cannot, f.ex. your University
#    This is done with this command: ssh -D 9999 username@server in another terminal
#    To use SOCKS call the program with the server and the port, in this case 127.0.0.1 and 9999
#     pubmedid2pdf.rb 19508715 127.0.0.1 9999
#
# == Usage 
#    pubmedid2pdf.rb pubmedid/s [server] [port]
