The tool provides a command‑line interface for batch renaming files using flexible pattern specifications. Users can supply a regular‑expression source pattern to capture parts of existing filenames, then define an output pattern with placeholders that reference those capture groups and optionally pad numeric values. It also supports natural sorting with enumerators, test or dry‑run modes, and options to preserve or discard file extensions, create missing directories, and overwrite existing targets.

It is aimed at developers and other users who need to rename large sets of files programmatically, such as source code, assets, or generated data. The utility can operate on a specified working directory, handle nested subdirectories with configurable depth, and generate a JSON map of original to new names for further processing.

The software is distributed as pre‑compiled binaries for Linux, macOS, and Windows, and can also be built from source with Rust. It is stable, available via cargo install, and includes documentation on regex syntax, placeholder formatting, and command‑line options.
