# version: 0.1, 16.2.2003
# changelog:
#
# 26.4.2007: Thanks to an input from Robert Regn, the script now handles 
#            filenames with points corretly (using stream editor sed)
#            If you do not have sed, you can uncomment the old code.
# 21.1.2004: Using IFS=. and set, we split filenames - but if you have 
#            filenames containing points, you loose the parts after first point
# 16.2.2003: Intial Version, generating double extensions
#
#this program is provided as is. no warranty at all.
