#todo: bei jeder Aenderung auch usage (doc) anpassen
#todo: translate entire script into english
# adds date taken in beginning of file name if jpg, .png, (not yet: .mp4, .mov, ...)
# Attention: there is a hard link to this script at the end!!! moving this script meens changing it
# options
# -h --help display help
# -a --noask --no-interactive do not prompt the user to confirm renaming
# -l --onlylog just logs what would have been done but not doing anything
# -o [file] --outputfile [file] specifies the output (log) file (standard is da.log)
# -v [file] --voutputfile [file] specifies the verbose output log file (standard dav.log)
# to be implemented in other sript:
# -i --image adds date taken in beginning of file name if jpg, .png, (not yet: .mp4, .mov, ...)
