[Boost-build] Refering to a target in a .jam file's folder

Hello,

I'm trying to do something that should be pretty easy but for some reason I 
can't figure out how... I don't know the bjam language so it's a real 
struggle :|

I have a .jam file of my own, which defines a custom rule that I use, and in 
that rule I need to refer to a target (a .cpp file) which resides in the 
same folder where the .jam file is. Note that this is not a jamfile; it is a 
jam file that is imported in an actual jamfile, which then uses the custom 
rule defined in the .jam file.

How is this done?

Thanks a lot,
Emil
