## Unzip a tarball to a temporary directory
|
||||
|
||||
Uncompress ([`flate2::read::GzDecoder::new`]) and
|
||||
extract ([`tar::Archive::unpack`]) all files form a zipped tarball
|
||||
named archive.tar.gz located in the current working directory
|
||||
inside a temporary directory ([`tempdir::TempDir::new`])
|
||||
and delete everything.
