### 8`` tar+gzip File Extraction

(require file/untgz) | package: base

The file/untgz library provides a function to extract items from a possible gzipped TAR/USTAR archive.

The same as untar, but if in is in gzip form, it is gunzipped as it is unpacked.

Changed in version 6.3 of package base: Added the #:permissive? argument.
