### Given one or more DOIs on the command line (with or without the
### "http://dx.doi.org/" prefix), generate rough BibTeX entries by
### online database lookup.
###
### This tool can be useful for recovering additional data, such as
### missing number and month values, for existing BibTeX entries.
###
### Usage:
###	doi-to-bibtex.sh doi-1 doi-2 ... > foo.bib
###	doi-to-bibtex.sh doi-1 doi-2 ... | bibclean > foo.bib
###	doi-to-bibtex.sh doi-1 doi-2 ... | fix-order.sh > foo.bib
###	doi-to-bibtex.sh doi-1 doi-2 ... | fix-order.sh | journal.sh > foo.bib
