NAME

       derb - disassemble a resource bundle

SYNOPSIS

       derb  [  -h,  -?,  --help  ]  [ -V, --version ] [ -v, --verbose ] [ -e,
       --encoding encoding ] [ --bom ] [ -l, --locale locale ] [  -t,  --trun-
       cate  [ size ] ] [ -s, --sourcedir source ] [ -d, --destdir destination
       ] [ -i, --icudatadir directory ] [ -c, --to-stdout ] bundle ...

DESCRIPTION

       derb reads the compiled resource bundle files  passed  on  the  command
       line and write them back in text form.  The resulting text files have a
       .txt extension while compiled resource bundle  source  files  typically
       have a .res extension.

       It is customary to name the resource bundles by their locale name, i.e.
       to use a local identifier for the bundle filename, e.g.  ja_JP.res  for
       Japanese  (Japan) data, or root.res for the root bundle.  This is espe-
       cially important for derb since  the  locale  name  is  not  accessible
       directly from the compiled resource bundle, and to know which locale to
       ask for when opening the bundle.  derb will produce a file  whose  base
       name is either the value of the -l, --locale option, or the same as the
       base name of the compiled resource file itself.  If the --to-stdout, -c
       option  is used, however, the text will be written on the standard out-
       put.

OPTIONS

       -h, -?, --help
              Print help about usage and exit.

       -V, --version
              Print the version of derb and exit.

       -v, --verbose
              Display extra informative messages during execution.

       -e, --encoding encoding
              Set the encoding used to write output files  to  encoding.   The
              default  encoding  is  the invariant (subset of ASCII or EBCDIC)
              codepage for the system (see section INVARIANT CHARACTERS).  The
              choice of the encoding does not affect the data, just their rep-
              resentation. Characters that cannot be represented in the encod-
              ing will be represented using \uhhhh escape sequences.

       --bom  Write a byte order mark (BOM) at the beginning of the file.

       -l, --locale locale
              Set  the  locale  for the resource bundle, which is used both in
              the generated text and as the base name of the output file.

       -t, --truncate [ size ]
              Truncate individual resources (strings or binary data)  to  size
              bytes. The default if size is not specified is 80 bytes.

       -s, --sourcedir source
              Set  the  source directory to source.  The default source direc-
              tory is the current directory.  If - is passed for source,  then
              the bundle will be looked for in its default location, specified
              by the ICU_DATA environment variable (or defaulting to the loca-
              tion set when ICU was built if ICU_DATA is not set).

       -d, --destdir destination
              Set  the destination directory to destination.  The default des-
              tination directory is  specified  by  the  environment  variable
              ICU_DATA  or  is the location set when ICU was built if ICU_DATA
              is not set.

       -i, --icudatadir directory
              Look for any necessary ICU data files in directory.   For  exam-
              ple,  when  processing collation overrides, the file ucadata.dat
              must be located.  The default ICU data directory is specified by
              the environment variable ICU_DATA.

       -c, --to-stdout
              Write the disassembled bundle on standard output instead of into
              a file.

CAVEATS

       When the option --bom is used, the character U+FEFF is written  in  the
       destination  encoding regardless of whether it is a Unicode transforma-
       tion format (UTF) or not.  This option should only be used with an  UTF
       encoding, as byte order marks are not meaningful for other encodings.

INVARIANT CHARACTERS

       The  invariant  character  set consists of the following set of charac-
       ters, expressed as  a  standard  POSIX  regular  expression:  [a-z]|[A-
       Z]|[0-9]|_| |+|-|*|/.  This is the set which is guaranteed to be avail-
       able regardless of code page.

ENVIRONMENT

       ICU_DATA  Specifies the directory  containing  ICU  data.  Defaults  to
                 /usr/lib/icu/3.4/.   Some tools in ICU depend on the presence
                 of the trailing slash. It is thus important to make sure that
                 it is present if ICU_DATA is set.
