NAME
     fiz - recover data from damaged Zoo archives

SYNOPSIS
     fiz archive[.zoo]

DESCRIPTION
     Fiz, the fix zoo utility, helps extract data from damaged
     archives.  When invoked on a zoo archive, fiz searches the
     archive for directory entries.  For each directory entry
     found, it prints the position of the directory entry within
     the archive (a decimal number), the associated path prefix
     if any, the short filename, and the long filename if any.
     The first directory entry listed (with a meaningless
     filename) is usually the archive header and should be
     ignored.  The last directory entry listed (with null direc-
     tory and file names) is the trailing null directory entry
     that every zoo archive contains and this too should be
     ignored.

     Fiz converts any unprintable characters encountered in a
     filename to printable equivalents before printing them.
     Control characters are converted to corresponding digraphs
     (e.g. control A becomes "^A") and characters with the eighth
     bit set are printed preceded by a tilde ("~").  If fiz
     detects a corrupted directory entry CRC (not the file data
     CRC), it indicates so.

     Make a record of Fiz's output by redirecting it to a file.
     Then list the undamaged files using Zoo version 1.41 or
     later as follows:

          zoo l@n archive [.zoo]

     where n is a position within the damaged zoo archive,
     obtained from the output of fiz. If n is properly chosen,
     the damaged portion of the zoo archive will be ignored and
     all remaining undamaged filenames will be listed.  To
     extract undamaged files use the command:

          zoo x@n archive[.zoo]

     where n is a decimal integer obtained from fiz.

     The @n option may be used in combination with all other
     legal options for zoo.

DIAGNOSTICS
     If fiz detects a CRC error in a directory entry it so indi-
     cates.  This simply serves as a warning and does not neces-
     sarily imply that the file data are corrupted.

FUTURE DIRECTIONS
     Currently fiz does not look for the file data, but only
     locates undamaged directory entries.  A future version will
     also search for the leader that precedes each archived file
     and permit extraction even if the corresponding directory
     entry is damaged.
