'''Implementation of imply_option().
Injects additional options as if they had been passed on the command
line. The `option` argument is a string as in option()'s `name` or
`env`. The option must be declared after `imply_option` references it.
The `value` argument indicates the value to pass to the option.
It can be:
- True. In this case `imply_option` injects the positive option
(--enable-foo/--with-foo).
imply_option('--enable-foo', True)
imply_option('--disable-foo', True)
are both equivalent to `--enable-foo` on the command line.
- False. In this case `imply_option` injects the negative option
(--disable-foo/--without-foo).
imply_option('--enable-foo', False)
imply_option('--disable-foo', False)
are both equivalent to `--disable-foo` on the command line.
- None. In this case `imply_option` does nothing.
imply_option('--enable-foo', None)
imply_option('--disable-foo', None)
are both equivalent to not passing any flag on the command line.
- a string or a tuple. In this case `imply_option` injects the positive
option with the given value(s).
imply_option('--enable-foo', 'a')
imply_option('--disable-foo', 'a')
are both equivalent to `--enable-foo=a` on the command line.
imply_option('--enable-foo', ('a', 'b'))
imply_option('--disable-foo', ('a', 'b'))
are both equivalent to `--enable-foo=a,b` on the command line.
Because imply_option('--disable-foo', ...) can be misleading, it is
recommended to use the positive form ('--enable' or '--with') for
`option`.
The `value` argument can also be (and usually is) a reference to a
@depends function, in which case the result of that function will be
used as per the descripted mapping above.
The `reason` argument indicates what caused the option to be implied.
It is necessary when it cannot be inferred from the `value`.
