/*
* Usage
* ~~~~~
*
* This simple program is aimed to be used as a workaround when installing over
* glibc which has placed glibc.so into /lib/i686.
*
* For example, in glibc.spec:
*
* %post -p /sbin/postshell
* /sbin/glibc-postinst /%{_lib}/%{_host_cpu}
* /sbin/ldconfig /%{_lib} %{_prefix}/%{_lib}
*
* Patches and bugreports are welcome, direct them to Elan Ruusamäe
* <glen@pld-linux.org>.
