I'd like to point out one important thing -- nothing in
the above list appears to be related to Boost.Build,
therefore it probably should not be discussed on Boost.Build list,
but on the boost-testing list, where I cross-post this email,
and where all follow-up should be directed.

As far as testing process_jam_logs goes -- would you mind telling
what's missing in the current output? Basically, an easy way
to test your changes is to run old process_jam_logs, run new process_jam_logs,
and make sure that the produced xml files are identical.

As far as library_status.cpp goes, I've just looked at SVN at it
appears that file has large blocks of code common to compiler_status.cpp.
Except that it was reformatted to use different indentation, which makes
it impossible to understand the real differences. I don't think this
code duplication is OK.

Speaking about compiler_status.cpp, what you say is false. Here's what I've
just did:

        cd .../libs/program_options/test
        bjam --dump-tests -d+2 > log 2>&1
        cat log | process_jam_log --v2
        compiler_status --v2 /home/ghost/Work/Boost/boost-svn status.html status-links.html

Everything is from SVN HEAD. I have got the attached two files, and they
make sense to me. The only problem with those files is that all 
tests are marked as having warnings; this is most
likely a result of:

        1. Somebody changing process_jam_logs, and
        2. Not reporting of warnings by the current web pages,
        so the bogus warning remained unnoticed.

We can probably fix that, but I surely don't think that copy-pasting 
compiler_status.cpp is the first approach to the fix.
