1//! Build-time version information, for `caproni version`'s output.
2//!
3//! Ported from `internal/buildinfo/buildinfo.go`. Go injects `version`,
4//! `commit`, and `date` via `goreleaser`'s `-ldflags`, defaulting to
5//! `"dev"`/`"unknown"`/`"unknown"` in a plain `go build`. This port uses
6//! `env!("CARGO_PKG_VERSION")` for `version()` (always accurate; Cargo
7//! always knows it, unlike Go's zero-value default), and `option_env!` for
8//! `commit()`/`date()`, which a release build sets via `XIANYUN_BUILD_COMMIT`/
9//! `XIANYUN_BUILD_DATE` environment variables at compile time, falling back
10//! to the same `"unknown"` Go defaults to otherwise.
