# This script is started by scanbuttond whenever a scanner button has been pressed.
# Scanbuttond passes the following parameters to us:
# $1 ... the button number
# $2 ... the scanner's SANE device name, which comes in handy if there are two or
# more scanners. In this case we can pass the device name to SANE programs
# like scanimage.
# *** WARNING ***
# The example code below contains just simple examples how things may get done.
# Don't simply uncomment the code on systems with untrusted users! This would
# make your button scanning vulnerable to various kinds of attacks by local users.
# *** WARNING ***
