+to customize the initialization, pass the parameter 'prelude'. Here is for example
+how to create a waf file using the compat15 module:
+$ ./waf-light --tools=compat15 --prelude=$'\tfrom waflib.extras import compat15\n'

+Any kind of initialization is possible, though one may prefer the build system kit (folder build_system_kit):
