NAME
       rezin - examine the resource fork of legacy files

SYNOPSIS
       rezin [options] ls [type [id]]

       rezin [options] cat type id

       rezin [options] convert type id

DESCRIPTION
       Rezin  provides	a  set of commands allowing one to examine and extract
       data from the resource fork of legacy MacOS files.  It  is  capable  of
       fetching  the resource fork from a number of different sources, includ-
       ing some which are functional even on systems which do  not  themselves
       support the resource fork (see "Sources" below)

       UTF-8  encoding	is  used  throughout  the  public interfaces of rezin.
       Resource type codes will always be composed of four unicode characters,
       but  as	a consequence of UTF-8 encoding, may not always be four bytes.
       Additionally, carriage returns will be converted to newlines  in  cases
       where text data is expected.

       The commands are as follows:

       ls     For  each type in the resource fork, print the code of that type
	      to standard output, one per line.

       ls type
	      For each resource of type type in the resource fork,  print  the
	      ID  and  name of that resource to standard output, one per line.
	      The ID and name will be separated by a single tab character.

       ls type id
	      If there is a resource with type type and ID id,	print  the  ID
	      and  name  of  that  resource to standard output, separated by a
	      single tab character.

       cat type id
	      Print the resource with type type and ID id to standard  output.

       convert type id
	      If  type is a known resource type (see "FORMATS" below), convert
	      the resource with type type and ID id to a suitable output  for-
	      mat, then print it to standard output.

	      If  type is not a known format, then print a warning to standard
	      error, and dump the resource in raw form to standard output.

OPTIONS
   Sources
       These options specify which resource fork to examine.  Exactly  one  of
       these options must be provided with each invocation of rezin.

       -a file | --apple-single=file
	      Read  from the AppleSingle-encoded file file. Both big- and lit-
	      tle-endian AppleSingle files are supported. Since rezin is  con-
	      cerned only with the resource fork, it will also accept the por-
	      tion of a AppleDouble-encoded file which contains  the  resource
	      fork.

       -f file | --flat-file=file
	      Read  from  the  flat  file  file.  On systems which support the
	      resource fork natively, it is possible to  read  from  a	file's
	      resource	fork by appending "/rsrc" to the path of that file, as
	      if it were a directory.

       -z archive,file | --zip-archive=archive,file
	      Read the resource fork of the file file within the  zip  archive
	      archive. This works even on systems which do not themselves sup-
	      port the resource fork.

   Output
       These options control the generated output of a	rezin  command.  These
       are optional.

       -l cr|nl|crnl | --line-ending=cr|nl|crnl
	      By  default, when reading strings, carriage returns will be con-
	      verted to newlines, to follow the Unix  line-ending  convention.
	      This  option  changes  that behavior. Valid values are cr (leave
	      them as carriage returns), nl (the default), and	crnl  (convert
	      to DOS line-endings).

FORMATS
       The following resource types are supported by rezin:

       'cicn' A  color	icon.  Color icons are typically 256-color images with
	      horizontal and vertical dimensions of 16, 32, or 64 pixels. How-
	      ever,  this  is  not a technical limitation, and other sizes and
	      colorings are possible. When using the 'convert' command, 'cicn'
	      data will be converted to PNG format.

       'clut' A  color table, stored in a MacOS-specific format. Each resource
	      can store up to 65536 RGB colors. When using the 'convert'  com-
	      mand,  'clut' data will be converted to a JSON array of strings.

       'snd ' Sound data, stored in a MacOS-specific format.  When  using  the
	      'convert' command, 'snd ' data will be converted to AIFF format.

       'STR#' Arrays of strings, stored in MacRoman  encoding.	Each  resource
	      can  store up to 65536 strings, with each string being up to 255
	      characters. When using the 'convert' command, 'STR#'  data  will
	      be converted to a JSON array of strings.

       'TEXT' Text data, stored in MacRoman encoding. When using the 'convert'
	      command, 'TEXT' data will be output as text.

BUGS
       Rezin currently does not handle many different resource types. In addi-
       tion,  it only supports monophonic 'snd ' data encoded using 8-bit sam-
       ples.
