# all files		-> without option
# TeX class files	-> option cls
# TeX style files 	-> option sty
# bibtex style files 	-> option bst
# bibtex database files -> option bib
# biblatex bibstyles 	-> option bbx
# biblatex citestyles 	-> option cbx
#
# with the help
# of kpsewhich and creates a
# bstFiles.lst, clsFiles.lst, styFiles.lst, bibFiles.lst,
# bbxFiles.lst, cbxFiles.lst
# without any parameter all files are created.

# Herbert Voss <voss@perce.org>
#
# Updates from Jean-Marc Lasgouttes.
#
# bib, bbx and cbx support added by Juergen Spitzmueller (v0.4)
#
# translated to python by Bo Peng, so that the script only 
# relies on python and kpsewhich (no shell command is used).
