%description
FEX allows you to run x86 and x86-64 binaries on an AArch64 host, similar to
qemu-user and box86. It has native support for a rootfs overlay, so you don't
need to chroot, as well as some thunklibs so it can forward things like GL to
the host. FEX presents a Linux 5.0 interface to the guest, and supports both
AArch64 and x86-64 as hosts.
