# aria-control-file-parser

[![PyPI](https://img.shields.io/pypi/v/parse_aria_control_file.svg)](https://pypi.org/project/parse_aria_control_file/)

> Parse `aria2c` control files from the command line.

The _.aria2_ (Control File) contains the hash info of the magnet link, so we can parse the file to get the original magnet link. This allows you to resume the download where it left off if it was cancelled or interrupted.
