Sapwood is a pixbuf-based 'theme' that allows you to configure the look of gtk-using programs. the programs need no modifications to use themes; the support is built into gtk+.

the engine is similar to the pixbuf engine, but uses client-server design and pixmaps rather than pixbufs. it is faster and more memory efficient than the pixbuf engine, but doesn't do scaling or gradients.

this package contains symbol tables for debugging.
