The usage with workspace

[dalance]

I want to use rust-skeptic with workspace.
My project structure is like below:

$ tree
.
|-- Cargo.lock
|-- Cargo.toml
|-- README.md
|-- crate-A
|   |-- build.rs
|   |-- Cargo.toml
|   |-- src
|   |   `-- lib.rs
`-- crate-B
    |-- Cargo.toml
    `-- src
        `-- lib.rs

I want to test README.md with crate-A, so build.rs of crate-A is below:

fn main() {
    skeptic::generate_doc_tests(&["../README.md"]);
}

This works fine with cargo test, but cargo package is failed.
This is because cargo package copies files in crate-A to target/package/crate-A-xxx, build.rs is executed in the target directory, and ../README.md can't be found.

My current workaround is below:

fn main() {
    let path = std::path::PathBuf::from("../README.md");
    if path.exists() {
        skeptic::generate_doc_tests(&[path]);
    }
}

Is there any idea to fix it?
I think either the improvement of rust-skeptic or the extra instruction of README.md is required.
