This fairly small gem can be used to extract different archive formats, such as .tar.bz2, .tar.gz, .tbz, .zip, .gem, .lzma and various more. Audio can be extracted as well, via ffmpeg, if the gem called multimedia_paradise is installed. This project, however had, depends on external tools, such as tar (on Linux) or 7z / 7zip (on Windows), so these have to be installed first. For more information about this project have a look at the homepage, at https://rubygems.org/gems/extracter.
