// Implementation of the Trash utility process. The trash implementation follows
// the XDG specification which maintains metadata in a user visible directory at
// ({TRASH_DIR}/info) and in files with a suffix .trashinfo. These files have a
// format as follows:
//   [Trash Info]
//   Path=/foo/bar.txt
//   DeletionDate=2011-10-05T14:48:00.000Z
// Where Path is relative to the parent of the {TRASH_DIR} and the DeletionDate
// is an ISO-8601 compliant string. This utility process parses this content and
// ensures both these values are well-formed and valid. Upon completion it
// responds with a status and the parsed contents.
