	Is there a way to using python.jam to configure multiple versions of 
Python?  We are slowly upgrading our computers from Python 2.5 to Python 
2.6.  It's a full OS upgrade so a computer only has one version installed.

	Our current 2.5-only configuration is:

--- Jamroot

# sysdefs.jam is a file in the same directory as Jamroot with
# configuration settings

import ./sysdefs ;

using python
    : 2.5
    ;

--- sysdefs.jam

    python-include-dir = /usr/include/python2.5/ ;
    numpy-include-dir = 
/usr/lib/python2.5/site-packages/numpy/core/include/numpy/ ;

alias python-include-base : : :
    : <include>$(python-include-dir) ;

# Numpy headers
alias numpy                              #FOR: Numpy
    : # no sources
    : # no build requirements
    : # no default build
    : <include>$(numpy-include-dir)
    ;


--- Jamfile (for the python extension)

python-extension compiledstats
    : compiledstats.cpp
      /sysdefs//numpy
      /sysdefs//boost-python
      /proj-libs/utilities
    ;


----

	For 2.6, I need to not only change the version number, but the location 
of the numpy headers (now in dist-packages, not site-packages).

	Can python.jam handle multiple versions?  Is there a more 
boost-build-esque way of doing this than a bunch of "ifs" and testing 
for file existence?
