boar will sniff any archive, and maybe even let you extract it.

Under the hood, it uses:

• https://github.com/itchio/savior - for resumable extraction
• https://github.com/itchio/dash - for file sniffing
• https://github.com/itchio/sevenzip-go - for the files we don't have a custom decompressor for

boar's code itself is under MIT License, see LICENSE for details.

• szextractor uses 7-zip, which is licensed under LGPL and BSD 3-clause, see https://www.7-zip.org/
• rarextractor uses dmc_unrar, which has LGPL and BSD clauses, see https://github.com/DrMcCoy/dmc_unrar
