- * fileunix.c - manipulate file names and scan directories on UNIX/AmigaOS

- * file_archscan() - scan an archive for files

- * timestamp, interested parties may later call file_time().

- * 04/08/94 (seiwald) - Coherent/386 support added.
- * 12/19/94 (mikem) - solaris string table insanity support
