# List of available options :
# * folder : folder in which papers are stored
# * proxies : list of proxies to use, e.g. ['', "socks5://localhost:4711"]
# * format_articles, format_books : masks to rename files

# Available masks to rename files are
# %f = last name of first author
# %l = last name of last author
# %j = name of the journal
# %Y = published year
# %t = title
# %a = authors
# %v = arXiv version (e.g. '-v1') or nothing if not an arXiv paper
