 EXAMPLES
 
     For a real-world example of a program the includes libev
     verbatim, you can have a look at the EV perl module
     (http://software.schmorp.de/pkg/EV.html).  It has the libev files in
-    the liev/ subdirectory and includes them in the EV/EVAPI.h (public
-    interface) and EV.xs (implementation) files. Only EV.xs file will be
-    compiled.
