About image builder, the wiki

*Image Generator* is the program that creates the OpenWrt firmware image
file. In the process of compiling OpenWrt
<http://wiki.openwrt.org/doc/howto/build>, *Image Generator* is coercively
created (compiled), because it is needed to eventually create the image
file. It is located in /openwrt/trunk/xxx and you can use it, to create
more image-files from the packages you obtained during compilation.

but I don't know what is "xxx" and also cannot find the "trunk" folder.
Could you please tell me where it is?
