Subject: [Boost-build] How can I include and use Jambase rules to my bjam/b2 build?

at work I tried to build an old software package (Ingres DBMS 10.1) from
source over the last two weeks. It contained Jamfile and Jamrules files
in its tree structure, so I concluded that I would have to use bjam/b2
to get things going. The project's documentation wasn't specific enough
about this point as it turned out.
I had one major problem, the Jamfiles would use a lot of definitions
from the "Jambase" file, like "SubDir" a.s.o. Everytime I started the
build, I would get the error "unknown rule", as you can also see in the
question that I posted on StackOverflow:
I finally decided to give an older Jam version a try, and voila: with
ft-jam 2.5.2 the project compiles flawlessly without any further ado. Yay!
So, basically everything is fine now and I can use ft-jam for my
purposes. But I still wonder whether I could also use bjam/b2 for the
compile. What is the purpose of the internal Jambase definition ("+"
file) and the "-f" option in bjam? Is it only for bootstrapping b2
itself, or can I use it while running b2? If yes, how do I activate it?
How does a MWE look in this case?
Feel free to answer my questions on SO directly. Otherwise I'll try to
provide an explanation myself, based on the replies from this list.
Thanks a lot in advance for any clarifications and pointers to
