I have a hierarchic structure in my project:
project
|__Jamroot
|__subproject1
|____Jamfile
|____...
|__subproject2
|____Jamfile
|____...
|__subproject3
|____Jamfile
|____...
|__...
.

When I run bjam in toplevel project, "path.pwd" in Jamfiles of subprojects shows me that current directory is path where i have run bjam.

So, all relative paths in Jamfiles are invalid. They are only valid, when bjam is run in subproject`s directory.

Is there any way to use relative paths in such manner?
