 <?/* bibtexbrowser : a PHP script to browse and search bib entries from BibTex files.
-* This script is a refactored, extended and repackaged version from an excellent script 
-* of the University of Texas at El Paso.
-* Demonstration site: https://www.ensieta.fr/~monperma/bibtexbrowser.php
-* Version : __VERSION__
-* Don't hesitate to contact me :-)
-*
-* (C) 2005-2006 The University of Texas at El Paso / Joel Garcia, Leonardo Ruiz, and Yoonsik Cheon

-*
-* Related works:
-*
-* bibhtml, bib2html, bibtohtml, bibtex2html, bibtex2web
-* Unlike them, bibtexbrowser is dynamic.
-* Thus, you do not need to regenerate the static HTML files each time the bib file changes,
-* and you can search any string in it. 
-*
-* "PHP BibTeX Database Manager", bibadmin
-* Unlike them, bibtexbrowser does not need a MySQL database. 
-*
-* SimplyBibtex has the same spirit and makes different architectural and presentation choices
-* but bibtexbroswer is much more lightweight (just one file!!)
-*
-* Misc: a matlab script is similar !! http://www.sat.ltu.se/publications/publications.m
-*
-*  USAGE: 
-*
-* /bibtexbrowser.php
-* displays the menu and all entries without filtering from the $filename hardcoded in the script
-*
-* /bibtexbrowser.php?bib=bibfile.bib
-* displays the menu and all entries without filtering from the file bibfile.bib
-*
-* /bibtexbrowser.php?bib=bibfile.bib&all
-* displays all entries
-*
-* /bibtexbrowser.php?bib=bibfile.bib&year=2004
-* displays all entries from year 2004
-*
-* /bibtexbrowser.php?bib=bibfile.bib&author="James+Russel"
-* displays all entries from author James Russel
-*
-* /bibtexbrowser.php?bib=bibfile.bib&tag=france
-* displays all entries with the keyword france
-* @book{discours-de-la-methode,
-*      author = "René Descartes",
-*      title = "Discours de la M{\'{e}}thode",
-*      year = 1637,
