%description
qemu-e2k is a linux-user-mode build of QEMU maintained by MCST
(git.openelbrus.ru), providing emulation of Linux applications built
for the Elbrus (e2k) instruction set, revisions elbrus-v2 through
elbrus-v6 (elbrus-v7 support is incomplete upstream).

%description static
This package provides a statically linked build of qemu-e2k, useful
for copying into a chroot or container image without dragging in
qemu-e2k's shared-library dependencies.
