Hi,

I would like to separate the following sub-libraries/modules 
chrono/stopwatches and thread/executors.

Could someone point me where can I find the things to do to split a 
library in submodules?
How to identify them?
How to have separated regression test pages?
What the new boostdev tool needs?
...

Best,
Vicente
