It's quite a while since my last post. Although I'm not there, just because of the terrible earth quake happened in SiChuan China, I can't sleep well and concentrate on my codes while people there are suffering. God bless them, hope they could recover with time passes.

Actually this has been done two weeks ago. After evaluate the amount of porting works, we could go on with the dependency check of a specific project. For Mozilla, I had shown a framework picture:

From this picture we know the components in the lowest level are "NSPR" and Cairo". Because "Cairo" is only a graphics base, so we will start from NSPR first. 

For other open source projects without such a components diagram, then how we could know its internal components dependency? I would sugguest taking a look at the build(configure && make) output, from this log everything is exposed even with any third party library used by that project. Anyway, large projects like Mozilla will take us more time to get everything clear. Also the more time we put on dependency check, the more clear we could get for a structural view, and the more easy for add or modify codes.
