#FINDBIB 2.3, Aug, 2007 K. Goldstein
#
################ FINDBIB 2.0, F. Nesti, August, 26, 1997 ###############
#
# This script builds a bibliography database from the latex source file.
#
# Usage: findbib foo.tex
#
# Every \cite{...} of a reference in SPIRES-Bibtex standard form
# (Author:YEARaa) or in the form of an arXiv reference
# (arXive-name/yymmnnn OR yymmnnn OR yymm.nnnn)
# is searched in WWW-SPIRES.SLAC.STANFORD.EDU and all the bibtex records
# are returned in a .BIB file.
#
# The value of the variable ARXIV sets the default arxiv to search if the
# cite is of the form \cite{yymmxxx}
#
# To change the default arxiv change the value below:
#
ARXIV='hep-th/'
#ARXIV='hep-ph/'
#
# The .BIB file will have the same name as the .TEX file
#
# The script uses awk, sed, lynx, bibtex and somes LaTeX. You will have to install
# these to make sure it works.
#
####################################################################
#
# How the script works:
#
# Steps:
# Generate an AUX file with LaTeX if not present,
# searches the AUX file for labels,
# searches SPIRES for records,
# writes them in $1.bib, renaming last as $1.bib.old,
# calls BibTeX on the file (!).
#
#
#
#
#######################################################################
#
# FINDBIB 2.1, May, 2007 K. Goldstein
#
# Changes:
#
# 1. Script updated to fix some changes on Spires website
#
# 2. Uses sort to remove dupilcate entries
#
# 3. Can search for author with double barrel surnames
#
# 4. every cite of the form \cite{yymmxxx} returns a hep-th reference.
# To change the default arxiv the value of ARXIV
#
# 5. every cite of the form \cite{yymm.xxxx} returns a new arxiv reference
#
# 6. Gratuitous comments added so that the script is easy to fix
# when spires changes their format
#
#######################################################################
# FINDBIB 2.2 : fixed some bugs
