# Error code E0136

#### Note: this error code is no longer emitted by the compiler.

More than one `main` function was found.

Erroneous code example:

    fn main() {
        // ...
    }

    // ...

    fn main() { // error!
        // ...
    }

A binary can only have one entry point, and by default that entry point is the `main()` function. If there are multiple instances of this function, please rename one of them.
