# Using built

This needs build.rs in the src parent directory. (Where Cargo.* lives.)

This creates a built.rs in the target directory, which gets included.

To get git information, you need to ```git tag 0.1.0``` the version.

(If you want that in the built info.)

Also, if you do anything with git -- it seems like you need to do
```cargo clean; cargo build``` so it redoes the built file.
It sounds like it isn't easy to tell when git has changed something,
at least from built's perspective.
