So, as a suggestion to clean up command line options for b2:

- could there be two b2 command line parameters, python2=2.x and 
python3=3.x, in order
   to support the current behavior of building python2 and python3 
bindings simultaneously (if found)?

- these would need to be parsed in src/kernel/bootstrap.jam?

- and in src/tools/python.jam, near line 778, there needs to be a check 
on the minor version
   specified by python2 or python3, respectively, if these parameters are 
set?

Unfortunately, I am not a jam expert, and I don't have any clue how 
command line parameters are actually passed to src/tools/python.jam for 
the version check...
