Still needs documentation and some cleanup.
Interface deliberately kept super simple/clunky to focus on the
concepts. Not something you'd actually want to use.
Sample session:
$ python Kconfiglib/examples/menuconfig.py Kconfiglib/examples/Kmenuconfig
======== Example Kconfig configuration ========
[*] Enable loadable module support (MODULES)
Bool and tristate symbols
[*] Bool symbol (BOOL)
[ ] Dependent bool symbol (BOOL_DEP)
< > Dependent tristate symbol (TRI_DEP)
[ ] First prompt (TWO_MENU_NODES)
< > Tristate symbol (TRI)
[ ] Second prompt (TWO_MENU_NODES)
*** These are selected by TRI_DEP ***
< > Tristate selected by TRI_DEP (SELECTED_BY_TRI_DEP)
< > Tristate implied by TRI_DEP (IMPLIED_BY_TRI_DEP)
String, int, and hex symbols
(foo) String symbol (STRING)
(747) Int symbol (INT)
(0xABC) Hex symbol (HEX)
Various choices
-*- Bool choice (BOOL_CHOICE)
--> Bool choice sym 1 (BOOL_CHOICE_SYM_1)
Bool choice sym 2 (BOOL_CHOICE_SYM_2)
{M} Tristate choice (TRI_CHOICE)
< > Tristate choice sym 1 (TRI_CHOICE_SYM_1)
< > Tristate choice sym 2 (TRI_CHOICE_SYM_2)
[ ] Optional bool choice (OPT_BOOL_CHOICE)
Enter a symbol/choice name, "load_config", or "write_config" (or press CTRL+D to exit): BOOL
Value for BOOL (available: n, y): n

Unsetting modules demonstrates one reason why it makes sense to have
.type be magic and change from TRISTATE to BOOL without modules
(<> = tristate, [] = bool). The C implementation uses the same trick.
(The original type is still available in .orig_type though.)
Piggyback printing of tristates as n, m, y in the warning for invalid
values in set_value().
