I am just wondering where the rofsbuild.exe, readimage.exe, and rombuild.exe binaries are from; were the binaries downloaded pre-compiled or were they self-compiled from the source code available from http://developer.symbian.org?

I am also wondering how come the obey generated from PNHT's program for rofsbuild to recompile the image looks like it's structured differently to the example syntax at:


I am just taking a look at the source code for the tools, and am hoping to find out if the current tools used right now is the same -- or a different version, and trying to understand how the OBEY file works (because the one generated by Nokia Editor is a lot simpler looking). Sorry if my questions seem a bit silly, as I don't really know programming~ Just a curiosity...
