DESCRIPTION
       The DeRez tool decompiles the resource fork of resourceFile according to the type declarations
       supplied by the type declaration files. The resource description produced by this decompilation
       contains the resource definitions (resource and data statements) associated with these type
       declarations. If for some reason it cannot reproduce the appropriate resource statements, DeRez
       generates hexadecimal data statements instead.

       A type declaration file is a file of type declarations used by the resource compiler, Rez.  The type
       declarations for the standard Macintosh resources are contained in the Carbon.r resource header file,
       contained in the Carbon framework.  You may use the ${RIncludes} shell environment variable to define
       a default path to resource header files. If you do not specify any type declaration files, DeRez
       produces data statements in hexadecimal form.

       This same process works backward to recompile the resource fork. If you use the output of DeRez and
       the appropriate type declaration files as input to Rez, it produces the original resource fork of
       resourceFile.

INPUT
       An input file containing resources in its resource fork.  DeRez does not read standard input. You can
       also specify resource description files containing type declarations.  For each type declaration file
       on the command line, DeRez applies the following search rules: 1.  DeRez tries to open the file with
       the name specified as is.

       2. If rule 1 fails and the filename contains no colons or begins with a colon, DeRez appends the
       filename to each of the pathnames specified by the {RIncludes} environment variable and tries to open
       the file.

OUTPUT
       Standard output.  DeRez writes a resource description to standard output consisting of resource and
       data statements that can be understood by Rez.  If you omit the typeDeclFile1 [ typeDeclFile2 ]...
       parameter, DeRez generates hexadecimal data statements instead.

       Errors and warnings are written to diagnostic output.

ALIAS RESOLUTION
       This command resolves Finder aliases on all input file specifications. Finder aliases are also
       resolved in the pathnames of any files included by specified resource definition files. You can
       optionally suppress the resolution of leaf aliases for the input resource file (with the -noResolve
       option).

STATUS
       DeRez can return the following status codes:

       0  no errors
       1  error in parameters
       2  syntax error in resourceFile
       3  I/O or program error

PARAMETERS
       resourceFile
              Specifies a file containing the resource fork to be decompiled.

       typeDeclFile1 [ typeDeclFile2 ]...
              Specifies one or more files containing type declarations. These type declarations are the
              templates associated with the information in the resource description. In addition to using
              those in the ${RIncludes} folder, you can also specify your own type declaration files.

              Note
              The DeRez tool ignores any include (but not #include), read, data, change, delete, and
              resource statements found in these files. However, it still checks these statements for
              correct syntax.

OPTIONS
       -c[ompatible]
              Generates output that is backward-compatible with Rez 1.0.

       -d[efine] macro [ = data ]
              Defines the macro variable macro as having the value data.  You can use this option more than
              once on a command line.

              macro  Specifies the macro variable to be defined.

              data   Specifies the value of macro.  This is the same as writing

                     #define macro [ data ]

                     at the beginning of the resource file.

                     If you do not specify data, DeRez sets the value of data to the null string. Note that
                     this still defines the macro.

       -e[scape]
              Prints characters that are normally escaped, such as \0xff, as extended Macintosh characters.
              By default, characters with values between $20 and $FF are printed as Macintosh characters.
              With this option, however, DeRez prints all characters (except null, newline, tab, backspace,
              form feed, vertical tab, and rubout) as characters, not as escape sequences.

              Note
              Not all fonts have all the characters defined.

       -i directoryPath
              Specifies the directory to search for #include files. You may specify this option more than
              once. Directory paths are searched in the order in which they appear on the command line.

       -is[ysroot] sdkPath
              Specifies the system SDK in which to search for include files and frameworks.  If omitted, the
              system root ("/") is assumed.

       -m[axstringsize] n
              Sets the maximum output string width to n, where n must be in the range 2-120.

       -noResolve
              Suppresses leaf alias resolution of the file or pathname for the input resource file thus
              allowing the resource fork of a Finder alias file to be decompiled. Finder aliases are still
              resolved on all resource definition file paths and on any files they may include.

       -only typeExpr [ (idExpr1[:idExpr2] | resourceName) ]
              Reads only resources of the type indicated by typeExpr.  An ID (idExpr1), range of IDs
              (idExpr1:idExpr2), or resource name can also be supplied to further specify which resources to
              read. If you provide this additional information, DeRez reads only the specified resources.

              This option can be repeated multiple times. Note that this option cannot be specified in
              conjunction with the -skip option.

              Note
              The typeExpr parameter is an expression and must be enclosed in single quotation marks. If you
              also specify an ID, range of IDs, or resource name, you must place double quotation marks
              around the entire option parameter, as in these examples:

              -only "'MENU' (1:128)"
              -only "'MENU' ("'"Edit"'")"

       -only type
              Reads only resources of the specified type. It is not necessary to place quotation marks
              around the type as long as it starts with a letter and contains no spaces or special
              characters. For example, this specification doesn't require quotation marks:

              -only MENU

              Escape characters are not allowed. This option can be repeated multiple times.

       -p     Writes progress and summary information to standard output.

       -rd    Suppresses warning messages emitted when a resource type is redeclared.

       -script Roman | Japanese | Korean | SimpChinese | TradChinese
              Enables the recognition of any of several 2-byte character script systems to use when
              compiling and decompiling files. This option insures that 2-byte characters in strings are
              handled as indivisible entities. The default language is Roman and specifies 1-byte character
              sets.

       -s[kip] typeExpr [ (idExpr1 [:idExpr2 ] | resourceName) ]
              Skips resources of the type indicated by typeExpr.  For example, it is very useful to be able
              to skip 'CODE' resources.

              An ID (idExpr1), range of IDs (idExpr1:idExpr2), or resource name can also be supplied to
              further specify which resources to skip. If you provide this additional information, DeRez
              skips only the specified resources.

              You can repeat this option multiple times. Note that this option cannot be used in conjunction
              with the -only option.

              Note
              The typeExpr parameter is an expression and must be enclosed in single quotation marks. If you
              also specify an ID, range of IDs, or resource name, you must place double quotation marks
              around the entire option parameter, as in this example:

              -skip "'MENU' (1:128)"
              -skip -only "'MENU' ("'"Edit"'")"

       -s[kip] type
              Skips only resources of the specified type. It is not necessary to place quotation marks
              around the type as long as it starts with a letter and does not contain spaces or special
              characters. For example, this specification doesn't require quotation marks:

              -skip CODE

              Escape characters are not allowed. This option can be repeated multiple times.

       -u[ndef] macro
              Undefines the preset macro variable This is the same as writing

              #undef macro

              at the beginning of the resource file. This option can be repeated more than once on a command
              line.

       -useDF Reads and writes resource information from the files' data forks, instead of their resource
              forks.

EXAMPLES
       The following command line displays the 'cfrg' resources in the CarbonLib library. The type
       declaration for 'cfrg' resources is found in the CarbonCore.r framework umbrella resource header
       file.

       /Developer/Tools/DeRez -I /System/Library/Frameworks/CoreServices.framework/Frameworks/
       CarbonCore.framework/Headers/ /System/Library/CFMSupport/CarbonLib CarbonCore.r

       In the following example, DeRez decompiles the 'itl1' resource ID 0 in the data-fork-based localized
       resource file in the HIToolbox framework.

       $ export RIncludes=/System/Library/Frameworks/Carbon.framework/Headers/

       $ /Developer/Tools/DeRez -only 'itl1' /System/Library/Frameworks/Carbon.framework/Frameworks/
       HIToolbox.framework/Resources/English.lproj/Localized.rsrc Carbon.r -useDF
