# This script creates udev rules from a usb_modeswitch.conf file. call with
# ./modeswitch.conf2udevrules.pl usb_modeswitch.conf > udev.rules, then double
# check the generated udev rules!
#
# you can add the devices which should be ignored (probably because they are
# handled by a different program) to @ignore, devices that need special udev
# rules can be added to print_custom().
