Common-Description: ProteanOS library packages are having their host architectures appended to their names, in order to allow coinstallation of different architecture builds of each library for the purpose of cross-building dependent source packages. For more information, see: . http://www.proteanos.com/dev/multiarch/ . Renaming library packages would temporarily break the installation of all other packages that depend on them, so temporary transitional packages are necessary. The libraries' source packages can't build such transitional packages themselves, because opkbuild automatically renames library packages and won't allow two binary packages in one source package to share the same name (before acrhictecture qualification). So the transitional packages are built by a separate source package called "malt", or "multiarch library transitions".
