+Compatibility idioms for builtins names
+
+This module adds names to the builtins module for things that we want
+to use in SCons but which don't show up until later Python versions than
+the earliest ones we support.
+
+This module checks for the following builtins names:
+
+ all()
+ any()
+ sorted()
+ memoryview()
+
+Implementations of functions are *NOT* guaranteed to be fully compliant
+with these functions in later versions of Python. We are only concerned
+with adding functionality that we actually use in SCons, so be wary
+if you lift this code for other uses. (That said, making these more
+nearly the same as later, official versions is still a desirable goal,
+we just don't need to be obsessive about it.)
+
+If you're looking at this with pydoc and various names don't show up in
+the FUNCTIONS or DATA output, that means those names are already built in
+to this version of Python and we don't need to add them from this module.
