+//! A Rust GitOps/symlinkfarm orchestrator inspired by GNU Stow. Useful for dealing
+//! with "dotfiles", and with git support as a first class feature. Configuration is
+//! done throug a single yaml file, giving it a paradigm that should bring joy to
+//! those that use declarative operating systems and package managers.
+//!
+//! Although this isn't really a case where it matters *that* much for performance,
+//! being written in rust instead of e.g. /janky/ scripting languages does also mean
+//! it is snappy and reliable, and the /extensive/ testing helps ensure regressions
+//! aren't introduced.
+//!
+//! That said, we're in 0.0.Z, *here be dragons* for now.
