+# TODO:
+#
+# This has the potential to grow into something with a really big life
+# of its own, which might or might not be a good thing. Nevertheless,
+# here are some enhancements that will probably be requested some day
+# and are worth keeping in mind (assuming this takes off):
+#
+# - A command to re-read / re-load the SConscript files. This may
+# involve allowing people to specify command-line options (e.g. -f,
+# -I, --no-site-dir) that affect how the SConscript files are read.
+#
+# - Additional command-line options on the "build" command.
+#
+# Of the supported options that seemed to make sense (after a quick
+# pass through the list), the ones that seemed likely enough to be
+# used are listed in the man page and have explicit test scripts.
+#
+# These had code changed in Script/Main.py to support them, but didn't
+# seem likely to be used regularly, so had no test scripts added:
+#
+# build --diskcheck=*
+# build --implicit-cache=*
+# build --implicit-deps-changed=*
+# build --implicit-deps-unchanged=*
+#
+# These look like they should "just work" with no changes to the
+# existing code, but like those above, look unlikely to be used and
+# therefore had no test scripts added:
+#
+# build --random
+#
+# These I'm not sure about. They might be useful for individual
+# "build" commands, and may even work, but they seem unlikely enough
+# that we'll wait until they're requested before spending any time on
+# writing test scripts for them, or investigating whether they work.
+#
+# build -q [??? is there a useful analog to the exit status?]
+# build --duplicate=
+# build --profile=
+# build --max-drift=
+# build --warn=*
+# build --Y
+#
+# - Most of the SCons command-line options that the "build" command
+# supports should be settable as default options that apply to all
+# subsequent "build" commands. Maybe a "set {option}" command that
+# maps to "SetOption('{option}')".
+#
+# - Need something in the 'help' command that prints the -h output.
+#
+# - A command to run the configure subsystem separately (must see how
+# this interacts with the new automake model).
+#
+# - Command-line completion of target names; maybe even of SCons options?
+# Completion is something that's supported by the Python cmd module,
+# so this should be doable without too much trouble.

+ Holder class for uniform access to SCons options, regardless

+
+ A SCons option value can originate three different ways:
+
+ 1) set on the command line;
+ 2) set in an SConscript file;
+ 3) the default setting (from the the op.add_option()
+ calls in the Parser() function, below).
+
+ The command line always overrides a value set in a SConscript file,
+ which in turn always overrides default settings. Because we want
+ to support user-specified options in the SConscript file itself,
+ though, we may not know about all of the options when the command
+ line is first parsed, so we can't make all the necessary precedence
+ decisions at the time the option is configured.
+
+ The solution implemented in this class is to keep these different sets
+ of settings separate (command line, SConscript file, and default)
+ and to override the __getattr__() method to check them in turn.
+ This should allow the rest of the code to just fetch values as
+ attributes of an instance of this class, without having to worry
+ about where they came from.
+
+ Note that not all command line options are settable from SConscript
+ files, and the ones that are must be explicitly added to the
+ "settable" list in this class, and optionally validated and coerced
+ in the set_option() method.
