libhpmud-dev binary package in Ubuntu Lunar riscv64

 The HP Linux Printing and Imaging System provides full support for
 printing on most HP SFP (single function peripheral) inkjets and many
 LaserJets, and for scanning, sending faxes and for photo-card access on
 most HP MFP (multi-function peripheral) printers.
 .
 Shared library that provides direct I/O for each process. Prior to
 hpmud, all I/O was serialized through hpiod, a monolithic I/O processor.
 The new hpmud direct I/O is faster. Hpmud supports parallel, USB and
 JetDirect connectivity.
 .
 With hpmud, HPLIP no longer has Linux specific libusb extensions. This
 means any UNIX/Linux derivative that supports libusb may work with
 HPLIP. A public HPLIP "C" API is exposed through hpmud. See hpmud.h
 for documentation. A Python wrapper for hpmud, called hpmudext, is also
 available.
 .
 This package contains the development headers necessary if you wish
 to build packages depending on libhpmud.
