- limiting menu display: "visible if" <expr>
This attribute is only applicable to menu blocks, if the condition is
false, the menu block is not displayed to the user (the symbols
contained there can still be selected by other symbols, though). It is
similar to a conditional "prompt" attribude for individual menu
entries. Default value of "visible" is true.
- numerical ranges: "range" <symbol> <symbol> ["if" <expr>]
This allows to limit the range of possible input values for int
and hex symbols. The user can only input a value which is larger than

Kconfig symbol existence
~~~~~~~~~~~~~~~~~~~~~~~~
The following two methods produce the same kconfig symbol dependencies
but differ greatly in kconfig symbol existence (production) in the
generated config file.
case 1:
config FOO
tristate "about foo"
depends on BAR
vs. case 2:
if BAR
config FOO
tristate "about foo"
endif
In case 1, the symbol FOO will always exist in the config file (given
no other dependencies). In case 2, the symbol FOO will only exist in
the config file if BAR is enabled.
