syntax: Feature gate #[start] and #[main] These two attributes are used to change the entry point into a Rust program, but for now they're being put behind feature gates until we have a chance to think about them a little more. The #[start] attribute specifically may have its signature changed. This is a breaking change to due the usage of these attributes generating errors by default now. If your crate is using these attributes, add this to your crate root: #![feature(start)] // if you're using the #[start] attribute #![feature(main)] // if you're using the #[main] attribute cc #20064 2015-01-16 10:55:24 -08:00			`#![feature(main)]`

allowing the entry point name to be something other than main add build tests 2013-01-11 18:08:01 +09:00			`#[main]`
			`fn main1() {`

			`mod foo {`
