+ * 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-postrm /%{_lib}/i686
+ *
+ * Patches and bugreports are welcome, direct them to Elan Ruusamäe
+ * <glen@pld-linux.org>.
