Undo a BagIt archive

The Bash script undo_bagit undoes an archive folder created according to the BagIt File Packaging Format, as designed by the Library of Congress and standardised under RFC 8493. It undoes the action of the make_bagit command: it removes the checksum manifests and the informative files and moves the contents of the data directory up one level. The program is part of Bash AVpres, released under a 3-Clause BSD License and provided “as is” without warranty or support of any kind.
