There's all sorts of things that have already, and can be done. Everyone that
wants a smaller boost can use bcp: http://www.boost.org/tools/bcp/bcp.html.
bjam can already run tests for individual libs as desired.
For the TR1 inclined, John Maddock has created an alpha of a TR1 only distro:
http://sourceforge.net/project/showfiles.php?group_id=7586&package_id=189383
On other Linux systems boost is already 'split up'. On my ubuntu system Boost
has components for each 'built library', tools, docs, etc. Here's the
relevant output of 'apt-get search boost'
libboost-dev - Boost C++ Libraries development files
libboost-python-dev - Boost.Python Library development files
libboost-python1.33.1 - Boost.Python Library
bcp - tool for extracting subsets of Boost C++ Libraries
bjam - Software build tool
boost-build - Build system
libboost-date-time-dev - set of date-time libraries based on generic
programming concepts
libboost-date-time1.33.1 - set of date-time libraries based on generic
programming concepts
libboost-dbg - Boost C++ Libraries with debug symbols
libboost-doc - Boost.org libraries documentation
libboost-filesystem-dev - filesystem operations (portable paths, iteration
over directories, etc) in C++
libboost-filesystem1.33.1 - filesystem operations (portable paths, iteration
over directories, etc) in C++
libboost-graph-dev - generic graph components and algorithms in C++
libboost-graph1.33.1 - generic graph components and algorithms in C++
libboost-iostreams-dev - Boost.Iostreams Library development files
libboost-iostreams1.33.1 - Boost.Iostreams Library
libboost-program-options-dev - program options library for C++
libboost-program-options1.33.1 - program options library for C++
libboost-regex-dev - regular expression library for C++
libboost-regex1.33.1 - regular expression library for C++
libboost-serialization-dev - serialization library for C++
libboost-signals-dev - managed signals and slots library for C++
libboost-signals1.33.1 - managed signals and slots library for C++
libboost-test-dev - components for writing and executing test suites
libboost-test1.33.1 - components for writing and executing test suites
libboost-thread-dev - portable C++ multi-threading
libboost-thread1.33.1 - portable C++ multi-threading
libboost-wave-dev - C99/C++ preprocessor library
I'd suggest that the RPM based distros might want to follow the lead of ubuntu
if that want smaller granularity boost packages.
