Treats your repo as a literal shadow of the filesystem and manages individual files (copy, prune, collect) rather than trying to be a full config framework. Notable bits: bidirectional 'collect' mode, section-based inserts for parts of big system files, a local state file to safely prune deletions, and flock-based concurrency handling — nice attention to messy real-world workflows. It's not reinventing the wheel in a crowded dotfile space, but it's a pragmatic, carefully thought-out approach that an ops person will reach for.
