#		convertbiblio: a script for converting standard
#		bibliography to the database format for BibTex/LaTex
#		use this script as a filter, e.g.:
#		convertbiblio listOfBibitemRefs.tex > somefilename.bib
#		and then replace the references in latex with the 2 lines:
#		\bibliographystyle{unsrt} % or prsty or something else
#		\bibliography{somefilename} % the output of convertbiblio
#		run latex / bibtex / latex / latex ... et voila!
#
#		(was rewritten in python, see convertbiblio.py)
