A GIT sub-repository, all Boost libraries are maintained as submodules,
AFAIU for simplicity they're called "modules" (here's the list:
https://github.com/boostorg). There is also a "main" module containing
all other submodules (https://github.com/boostorg/boost). It should be
cloned with --recursive option to clone all of the submodules, etc.
In previously used SVN repository all libraries were just stored as
separate directories in one global repository, GIT allows to handle them
more or less separatelyas submodules.
Correct me if I'm wrong. To allow dividing libraries into smaller
functional parts (SVN) "sublibs" system was introduced. With it it's
possible to keep the tests and examples separated for each part. In the
library there must be a correct directories structure and there must
exist a file called "sublibs", see (geometry, numeric, functional,
etc.). Then you can see separated sublibs e.g. on the regression summary
As for your question, it depends how much splitting your library
requires, but I'm assuming that splitting it on a "sublibs"level would
be enough. Therefore the directories structure of your library should
look like this:
| | +-Jamfile.v2
| | +-Jamfile.v2
Each sublibtest dir should be added to the BOOST_ROOT/status/Jamfile.v2
to run the tests for all submodules.
It's on your own how to structure the sourcecode in
BOOST_ROOT/libs/library_name/include/boost/library_name. Each sublibrary
should probably have separate directory and it could be possible to
include the whole library or separate sublibs. But that depends on the
There must also be one "doc" directory with a documentation of a library
but I think it should be possible to split it into parts as well and
just include them from the library docs. If not it could be divided the
same way like headers.
