This library is part of the enlightenment foundation libraries (efl). it interfaces directly with libudev, avoiding such middleman daemons as udisks/upower or hal, and gathers device information when it becomes known to the system. this can be used to determine such things as:
- if a cdrom has a disk inserted
- the temperature of a cpu core
- the remaining power left in a battery
- the current power consumption of various parts
- monitor in realtime the status of peripheral devices
