A utility to fetch and download python packages
Why this project?
This project exists as the last piece to complete the puzzle of a package manager. The other pieces are:
- resolvelib - Resolves concrete dependencies from a set of (abstract) requirements.
- unearth (This project) - Finds and downloads the best match(es) for a given requirement.
- build - Builds wheels from the source code.
- installer - Installs packages from wheels.
They provide all the low-level functionalities that are needed to resolve and install packages.
Requirements

Installation
$ python -m pip install --upgrade unearth
