Is there C++ library for packaging and reading multiple files to/from one file

Question

Is there some small library for C++, or would be too much of a trouble to create one that "packs" (not compress) multiple game files into one bigger file (something like Valve .gcf) and reading from application should be easy; like accessing ordinary stored file.

If not, how much troublesome do you think would be to make one?

I'm aiming to some kind of simple use, something like:

my_asset_file->setAssetFile(ASSET_FOLDER + '/file.ext');
Model *m = new Model();
m->loadFromTxtFile(my_asset_file->openTxtFile('models/props/lamp.obj'));

PhysicsFS should be able to handle it.
