### QUICK IMAGE VIEWER "qiv-command" file
### http://qiv.spiegl.de/
###
### This file will be launched by QIV if you push 0-9 (or any other free key)
### NEW: Now you can use all free keys for qiv-command.
### NEW: If you press "X" followed by any string,
### qiv-command is called with X and this string
###
### Just put it in a directory that is in your path
###
### Note:
### If the first line of the output is like "NEWNAME=xxxxxxx" then qiv
### thinks that the filename of the currently displayed image has
### changed to this new name and updates its internal filelist.
### This is very useful when using qiv-command to rename files.

# used by most Digital Cameras. v2.6 by Matthias Wandel, Dec 26 2006
# http://www.sentex.net/~mwandel/jhead mwandel@sentex.net
