- make it run correctly when called by the 'root' user
    - internal_setarch: optionally run 'setarch' internally. This eliminates
        the need to run "setarch i386 mock ..." when building on target_arch !=
        build_arch. This is turned on by default. Limitations: must have
        'ctypes' python module available, which is only available by default in
        python 2.5, or as an extension module in <= 2.4. If the 'ctypes' module
        is not available, this feature will be disabled and you must manually
        run 'setarch'.
    - Does not run 'clean' action for 'shell', 'chroot', 'install', or
        'installdeps' (docs updated)
    - fix build for top_builddir != top_srcdir
    - fix 'installdeps' so that it works with both rpms/srpms
    - missing device file /dev/ptmx was causing 'expect' command to always
        fail. Affected any SRPM build that used 'expect'.
    - hard spec file dep on python >= 2.4 due to python syntax changes.
    - resultdir can now contain python-string substitutions for any variable in
        the chroot config. rebuild my.src.rpm
    - add 'dist' variable to all chroot config files so that it is available
        for resultdir substitutions.
    - give good error message when logging.ini cannot be found.
    - change default logging format to remove verbosity from build.log.
    - make logging format configurable from defaults.cfg or chroot cfg.
    - less verbose state.log format
