Creative Labs Nomad Jukebox library tools
libnjb is a C library and API for communicating with the Creative NOMAD JukeBox and Dell DJ digital audio. The protocol these devices use is presumably called PDE (Portable Digital Entertainment protocol) at Creative. Newer devices using the Microsoft MTP (Media Transfer Protocol) are not supported. . This package contains the library tools each performing a simple function, such as transferring a track to the jukebox. The source code for these tools is in the package libnjb-doc.
