Hi,

In additional to tarball capability, I'd like the ability to build and 
run bcp by calling a rule with a list of targets and/or files to scan 
for boost dependencies and a destination path for the dependencies to be 
copied to. A calling syntax as simple as:
[ bcp
    : # sources
         some-lib-target
         some-exe-target
         /path/to/some-file.cpp
    : # requirements
         <location>/path/in/which/to/put/dependencies
] ;
would be excellent. This capability would synergize with a tarball rule 
like mine or John Bito's suggestion.

Since bcp is simple to build but has some boost dependencies 
(filesystem, regex, and prg_exec_monitor), I found it expedient to put a 
prototype bcp rule in the boost.jam extension written by grafik:
https://svn.boost.org/trac/boost/browser/sandbox/tools/build_extensions/ext/boost.jam
We're already using boost.jam in our project to set up and build our 
project's boost dependencies, and I've added support for a few extra 
libraries as well. I just added support for the test library to get bcp 
to build.

Has anybody else using boost-build land done something similar? Is 
bcp.jam already out there and I missed it? If not, I figure this will be 
a great addition to grafik's boost.jam, or possibly a corollary to it.

Thanks,
Matt
