[Boost-build] BBv2 running a command on libraries (transfroming a library into a library)

Hi,

I'm trying to port a make file over to BBv2 and I was wondering about
the following situation:

foo.lib -> filteringcommand -> bar.lib

i.e. I'd like to take a library I've just built and then run a few
commands on it transforming it into a different output library.

As an example, run 'lmstrip' which changes the names of some symbols
exported by the library.

Am I right in assuming this is best handled using a 'make' rule?

make bar.lib : foo.lib : do-lmstrip ;

actions do-lmstrip
{
  lmstrip command here...
}

I also want to version some symbols, looking at the docs it appears I
can do this by extending the link command (of gcc) to understand a
feature <export-symbols>  or some such. Does anybody else need this
and whats a good name to use?

If I want to do this it must only pass the option
--version-script=filename if the file exists otherwise you get errors
- whats the appropriate way of handling this in an action?

It would also be useful to be able to tweak the link command line to
insert things like -Bsymbolic at the required place, is there an
option to insert such things before a target is used in a link line?
or should I just resort to similar make rules tfor such fine control?

Thanks

Kevin
