Have method for file path about man HOT 3 OPEN

Alternative proposal

Introduce render_to which accepts a W: Writer directly instead of allocating a string internally.

for man in gen_manuals(&app) {
    let path = PathBuf::from(env!("CARGO_PKG_NAME")).push(man.path());
    man.render_to(fs::File::create(&path)?)?;
}

This is more work and it will only be really useful if we manage to add a similar API to our roff crate (not that hard), too; rroff already works like this internally.

Perhaps we could make this a good first issue to help onboard someone?

@killercup oh I like that a lot! - I reckon if we go with your approach, we should also introduce a method to at least have access to the name. E.g. so if people choose to go with a deviating approach (for whatever reason) at least the basic requirements are available to them.
