graftfs 1.2.2

A Rust implementation of the GNU stow utility for managing dotfiles. It is a symlink farm manager that takes separate packages of software and/or data and makes them appear to be installed in the same place. Features include stow, delete, and restow operations, simulation mode, directory folding, and regex-based ignore/override patterns.
