- * is_tar() -- figure out whether file is a tar archive.
- *
- * Stolen (by the author!) from the public domain tar program:
- * Public Domain version written 26 Aug 1985 John Gilmore (ihnp4!hoptoad!gnu).
- *
- * @(#)list.c 1.18 9/23/86 Public Domain - gnu
- * $Id: is_tar.c,v 1.13 2000/08/05 17:36:48 christos Exp $
- *
- * Comments changed and some code/comments reformatted
- * for file command by Ian Darwin.
