      --  Work around the lack of a "prefix =" keyword argument to the
          Python 2.[12] version of the mktemp module.

  Fix the Scanner hash unit test for Python 2.5.  (Yes, it still works
  on previous versions, too.)

  r2007 | stevenknight | 2007-06-14 13:56:35 -0500 (Thu, 14 Jun 2007) | 4 lines

  Performance improvement when looking up Nodes:  don't use is_String(),
  just check for the initial '#' that specifies a top-relative lookup,
  and handle the exceptions.
........
  r2008 | stevenknight | 2007-06-14 16:57:47 -0500 (Thu, 14 Jun 2007) | 11 lines

  First step in refactoring command-line flag processing: Split out the
  current processing into its own module, with minimal additional changes.
  Among the minimal changes:
    --  Store delayed warnings (for deprecated --debug= keywords)
        in the option parser object, not in a global variable.
    --  Remove the OptParser variable itself from the SCons.Script globals.
        It's going to change significantly (and no one's probably using
        it anyway).
    --  Don't move definition of the --version output with the OptParser,
        keep it in Main.py.
........
  r2009 | stevenknight | 2007-06-15 08:15:25 -0500 (Fri, 15 Jun 2007) | 3 lines

  Refactor the test/explain.py script into three individual scripts
  so it's easier to deal with.
........
  r2010 | stevenknight | 2007-06-15 09:49:07 -0500 (Fri, 15 Jun 2007) | 3 lines

  Handle Aliases in --debug=explain.  This is kind of hard-coded for the
  normal lookup, and should be better handled by the signature refactoring.
........
  r2011 | stevenknight | 2007-06-15 17:25:37 -0500 (Fri, 15 Jun 2007) | 5 lines

  Refactor use of the command-line parser object so it's localized to the
  top-level main() function, and not passed down through _exec_main() or
  to _main() itself.  Replace its functionality with use of an exception to
  signal that the top-level main() function should print its help message.
........
  r2012 | stevenknight | 2007-06-17 23:34:26 -0500 (Sun, 17 Jun 2007) | 2 lines

  Remove unnecessary import of __main__.
........
  r2013 | stevenknight | 2007-06-17 23:48:06 -0500 (Sun, 17 Jun 2007) | 2 lines

  Pass the options object to _main(), don't use a global.
........
  r2014 | stevenknight | 2007-06-18 00:12:09 -0500 (Mon, 18 Jun 2007) | 6 lines

  Qt test fixes for Windows:
  Link against a static library created by the test infrastructure,
  not a shared library.
  Escape backslashes in Windows path names.
  Skip test/QT/Tool.py if Qt isn't installed.
........
  r2015 | stevenknight | 2007-06-18 10:46:17 -0500 (Mon, 18 Jun 2007) | 3 lines

  Support GetOption('no_exec'), and update test/NodeOps.py to use it
  instead of reaching into the SCons.Script.Main internals.
........
  r2016 | stevenknight | 2007-06-18 11:04:39 -0500 (Mon, 18 Jun 2007) | 4 lines

  Restore use of a global delayed_warnings variable so the chicken-and-egg
  warning from trying to use --debug=memoizer on Python versions without
  metaclasses has somewhere to go.
........
  r2017 | stevenknight | 2007-06-18 11:37:59 -0500 (Mon, 18 Jun 2007) | 3 lines

  Have the test infrastructure create a mock Qt shared library on UNIX,
  static library on Windows.

  general and more efficient must_be_same() method.
........
  r2025 | stevenknight | 2007-06-19 20:56:10 -0500 (Tue, 19 Jun 2007) | 3 lines

  the bound directory.Entry() method.
........
  r2033 | stevenknight | 2007-06-20 20:03:23 -0500 (Wed, 20 Jun 2007) | 5 lines

  The --debug=count option doesn't work when run with Python - O, or
  from optimized compiled Python modules (*.pyo files), because the
  counting is all within "#if __debug__:" blocks that get stripped.
  Print a warning so it doesn't look like --debug=count is broken.
........
  r2037 | stevenknight | 2007-06-21 10:42:40 -0500 (Thu, 21 Jun 2007) | 3 lines

  Replace the _stripixes() function with a more efficient/readable version
  that was checked in, but commented out, prior to 0.96.96.
........
  r2040 | stevenknight | 2007-06-21 12:18:57 -0500 (Thu, 21 Jun 2007) | 2 lines

  Ignore *.pyo files, too, since one of the tests now generates them.
........
  r2051 | stevenknight | 2007-06-26 15:11:57 -0500 (Tue, 26 Jun 2007) | 5 lines

  Arrange for graceful shutdown of the worker threads by writing None to
  the requestQueue and having the worker threads terminate their processing
  loops when they read it.  We can then .join() the threads, to wait for
  their termination, avoiding exceptions in the threading library module.
........

  Skip the scons-time tests if the Python version can't import __future__.

  when using certain systems/compilers.

  (Adam Simpkins)

  r2087 | stevenknight | 2007-07-03 12:22:10 -0500 (Tue, 03 Jul 2007) | 7 lines

  Get rid of unnecessary subclassing and complicating overriding of
  __init__() and parse_args() methods in favor of more straightforward
  initialization of the OptionParser object.

  We may need to restore subclassing in the future, but if so we'll do it
  in a more OO way.
........

........
  r2091 | stevenknight | 2007-07-04 03:35:17 -0500 (Wed, 04 Jul 2007) | 5 lines

  Use the new optparse compatibility module for command-line processing,
  and remove the SCons/Optik/*.py modules, with appropriate subclassing
  in Script/SConsOptions.py to preserve the way we print help text and
  SCons error messages.
........
  r2108 | stevenknight | 2007-07-08 22:57:08 -0500 (Sun, 08 Jul 2007) | 3 lines

  Make all of the optparse.add_options calls more-or-less consistent in
  how they call the keyword arguments.
........
  r2109 | stevenknight | 2007-07-09 12:31:01 -0500 (Mon, 09 Jul 2007) | 6 lines

  Handle initialization of command-line repository options by passing the

-
-    Instance attributes:
-      usage : string
-        a usage string for your program.  Before it is displayed
-        to the user, "%prog" will be expanded to the name of
-        your program (os.path.basename(sys.argv[0])).

-        this program
-      _short_opt : { string : Option }
-        dictionary mapping short option strings, eg. "-f" or "-X",
-        to the Option instances that implement them.  If an Option
-        has multiple short option strings, it will appears in this
-        dictionary multiple times.
-      _long_opt : { string : Option }
-        dictionary mapping long option strings, eg. "--file" or
-        "--exclude", to the Option instances that implement them.
-        Again, a given Option can occur multiple times in this
-        dictionary.
-      defaults : { string : any }
-        dictionary mapping option destination names to default
-        values for each destination.
-
-      allow_interspersed_args : boolean = true
-        if true, positional arguments may be interspersed with options.
-        Assuming -a and -b each take a single argument, the command-line
-          -ablah foo bar -bboo baz
-        will be interpreted the same as
-          -ablah -bboo -- foo bar baz
-        If this flag were false, that command line would be interpreted as
-          -ablah -- foo bar -bboo baz
-        -- ie. we stop processing options as soon as we see the first
-        non-option argument.  (This is the tradition followed by
-        Python's getopt module, Perl's Getopt::Std, and other argument-
-        parsing libraries, but it is generally annoying to users.)
-
-      rargs : [string]
-        the argument list currently being parsed.  Only set when
-        parse_args() is active, and continually trimmed down as
-        we consume arguments.  Mainly there for the benefit of
-        callback options.
-      largs : [string]
-        the list of leftover arguments that we have skipped while
-        parsing options.  If allow_interspersed_args is false, this
-        list is always empty.
-      values : Values
-        the set of option values currently being accumulated.  Only
-        set when parse_args() is active.  Also mainly for callbacks.
-
-    Because of the 'rargs', 'largs', and 'values' attributes,
-    OptionParser is not thread-safe.  If, for some perverse reason, you
-    need to parse command-line arguments simultaneously in different
-    threads, use different OptionParser instances.
