I'm working on a frame concept, which is something like a bidirectional
buffer. It allows to prepend and append binary data, and obtain/remove the
header and the trailer.

In addition we can split a frame in fragments and join fragments to make a
frame.

All these features are needed when working with protocol stacks.

Vicente
