Not that I have ever seen. Though I had also never seen use of $(self) 
before I dumped all the variables with one of the -d options.

I think it would be a little complicated to get right. It would need to 
be embedded in the executable which would mean it would need to be 
changed when installed, it could put in a file, but then where do you 
put that file so boost-build can always find it.

Another option would be to just get rid of boost-build.jam and move all 
its logic into boost-build itself. I am not sure if there are many uber 
important use cases that need it. I have found it useful for doing some 
additional boost locating and then using 
https://github.com/thomassuckow/SystemBoost to link against the system 
install of boost. If you have subprojects with their own SystemBoost 
then boost-build will get pissy that you are creating multiple /boost 
references with different directories. Though maybe there is a better 
way that how I have done it.
