You will need to write a custom generator for the T file. If you look at
what the C generators are doing, you'll find out how they are scanning
for H/HPP dependencies and adding them to BBv2.

Essentially, all you need to do is take your scanned list of CPP files and
add them to the list of sources. You may need to do something with them
to get BBv2 to be able to process them.

IIUC, you also want to process the T file to generate the files, so the
A.[h|c]pp files will be in msvc-7.1/release, etc. For this, you can also
look at the verbatum generator in the BBv2 documentation.

That's all the information I can give you. Vladimir Prus would be able to
give you more info if needed.

The only other thing I can suggest is to look through the Boost Jamfile.v2
files for the Boost libraries as some of these are using some neat tricks.
