Font selection, cartoon characters and text all came from different
sources FWIW, so if there is a conspiracy here, some evil genius is
masterminding it without the puppets being aware. :-) Seriously though,
I put forward a patch yesterday to partially address this. It's been
approved and submitted to PQM now.

I've raised bug #207557 accordingly.

It's a control directory.

Understood. I personally started learning Bazaar from the man-page which
I've since expanded to become the User Reference. I also like to know
exactly what a tool can do and go from there.
The thing to keep in mind though is that workflows are the "soul" of
Bazaar IMO. Bazaar is about staying out of your way and helping you get
things done, so the workflow models - not the DAGs underneath - are the
foundation from which I personally believe Bazaar ought to be explained
from. To me, development is about collaboration and I honestly want to
be focussing on that. My gripe with many other DVCS tools is that they
make collaboration first-and-foremost a DAG-management exercise. OK,
it's not quite that black-and-white but I value a simple process model
with an underlying complex data model (ala Bazaar) over a complex
process model with an underlying simple data model (ala Git).

I think your workflows are common and ought to be included. I also think
we ought to be fixing (b). If you write up your workflows on a Wiki
page, I'll use that as the basis for additional User Guide content. I'm
sure you and others have plenty of associated tips and tricks that we
ought to be sharing more widely in an effort to distil best practices.

I feel chapters 3 and 4 are fundamental and applicable to nearly every
Bazaar user. I probably need to make that clearer in the introduction.

I'm happy to include this but in an appendix say. I found the early
placement in the Hg book jarring.

Thanks. It takes time and thought to constructively review and critique
a 100 page manual. Much appreciated.
