-# This script takes LaTeX .aux files as input. It extracts all citations made
-# with page number information. These, together with the bibliography data base
-# extracted from the input and a .bst file are processed by bibtex to get a
-# file that associates each citation label with corresponding authors. Together
-# with the knowledge of which work is cited on which page, this is used to
-# compute which author is cited on which page. This information is written to
-# the output in form suitable to be included in a LaTeX document.
-# Alternatively, the script can also extract the label that appears in the
-# references for each work instead of the pages. Also, output for further
-# processing by makeindex can be generated instead of a 'ready' LaTeX file.
