# Script by dircha from ob list on 05/17/04
# suggested improvements by John Russell on 05/17/04 implemented 
# a year later by Kacper Wysocki.
# 05/30/05 - Kacper Wysocki
# - opens files with 'rox', which launches appropriate file handler
# - hidden directories now stay hidden
# - spaces, ampersands in dir- and filenames are escaped
# - newlines at each entry to make output a little readable
# 06/04/05 - Kacper Wysocki
# - use $0 for scriptname
# - use $ENV{'HOME'} as default path
# - now follows symlinks
