how to skip regenerating the dependency tree

(I'm sorry, I know this has been discussed before but have found no link 
to an explanation on how to use it).

I guess bjam first generates the whole dependency tree (parsing all 
includes and following them) and then verifies the 'last change date' of 
all nodes in this tree.

Now bjam takes quite some time before issueing its first compile or link 
command so I figured: is there anyway to skip the recreation of the 
dependency tree ?

Basically this comes down to equivalent of doing 'make' without first 
running 'make depend'.
