# texclean -- clean up after tex
#
# SYNOPSIS:  Remove *.log, *.blg, *.dvi-err, *.ilg output files.
#	Giving prefixes causes only files with names starting in that list
#	to be removed.
#	If the -d option is given, removes the *.dvi-alw and *.dvi files also.
#	If the -f option is given, removes the *.aux, *.bbl *.glo *.idx *.ind
#       *.lof *.lot and *.toc files also (but not *.dvi and *.dvi-alw files)
