 libmtp is a library for communicating with MTP aware devices in POSIX
 compliant operating systems. It implements MTP Basic, the subset
 proposed for standardization.

 The Media Transfer Protocol (commonly referred to as MTP) is a devised
 set of custom extensions to support the transfer of music files on
 USB digital audio players and movie files on USB portable media players.

 This package provides mtp-probe, a program to probe newly connected
 device interfaces from userspace to determine if they are MTP devices,
 used for udev rules.
