mntd is an automount daemon and shared library written for automatically mounting hotplug devices such as USB sticks, Compact Flash cards, or other mountable devices on Linux 2.4.x and 2.6.x kernels. You only have to plug in your hotplug device and wait a little bit. The library can be used for user mode programs that want to be informed when devices are mounted and unmounted. It will use now devfs to get the device changes. So no need for hal and udev any more.
con:cern is a workflow engine based on an extended case handling approach. A process is described as a set of activities with pre- and postconditions. An activity is executed when its preconditions are met. It manipulates the process item, thereby creating postconditions. The process flow is determined at runtime. This approach is superior to the conventional process flow approach, especially if high flexibility and modularity are required.
