does pre-processor support #else #elseif or #not directive?

[easyfrog]

I see the example in readme only have #if #endif, so does pre-processor support #else #elseif or #not directive?

[zxcat]

the only line used to find directives is

rollup-plugin-re/src/index.js

Line 246 in f0d5e56

let source = /\/\/\s#if\sIS_DEFINE(.*)([\s\S]*?)\/\/\s#endif/g.source

so there is no support of anything else
