wmaker-utils binary package in Ubuntu Mantic riscv64

 Written by Alfredo Kojima almost from scratch, resembles the NeXTStep look
 very closely, and it is now an official GNU project. Window Maker (originally
 named WindowMaker) is not overloaded with features, and it is easier to
 configure than most other window managers. Its final goal is to produce a
 window manager that doesn't require editing of configuration files.
 Window Maker is fast and doesn't require tons of memory to run.
 .
 This package contains wxcopy and wxpaste, two utilities ordinarily shipped with
 Window Maker but not depending on it or any of its libraries. These
 utilities allow users to interact with cut buffers on the command line.
