* Common code extracted to Python directories. * Read ~/.scons file for scons environment defaults. * Override scons settings with shell environment variables. * New "tags" for debug, nodebug, optimize, nooptimize builds. * Universal platform detection. * Default value of environment variables set through prefix dictionaries. * Check for correct Boost value and fail otherwise. * Extract git describe --tags into a preprocesor variable, -DTIP_BRANCH * More colors - blue for unchanged defaults, green for changed defaults, red for error. * Contain unit tests for non-obvious stuff. * Check to see that boost libraries have been built. * Right now, we accept both .dylib and .a versions but it'd be easy to enforce .a only.
