 =====
 
-Make sure you have libev* and python (for waf) installed, then:
+When running from git (should not be necessary when building from tar),
+requires automake, autoconf and friends:

-$ ./waf build
+$ ./autogen.sh
 
-See ./waf --help for available configure options and other commands available.
+Then:
 
+$ ./configure
+$ make
 
-INSTALL
