Hi Diptopal,

Definitely. It's an aid to understanding the code, not a standalone
tutorial. It is not complete, nor is it all up to date. Once you
understand an area, you may like to contribute patches to improve the
manual for future readers.

The Embecosm application notes try to provide some of this. Partly by
putting individual routines in a bigger context, and partly by
explaining "why" as well as "how" things happen. But they only touch the
surface. They should help you understand the internals manual better,
but they don't replace it.

You may like to look at the Embecosm Application Note 3 early on, to
help you understand the GDB internals manual.
