NAME
       derb - disassemble a resource bundle

SYNOPSIS
       derb [ -h, -?, --help ] [ -V, --version ] [ -v, --verbose ] [ -e,
       --encoding encoding ] [ --bom ] [ -l, --locale locale ] [ -t,
       --truncate [ 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
       especially 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
       output.

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
              representation. Characters that cannot be represented in the
              encoding 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
              directory 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 location set when ICU was built if ICU_DATA is not set).

       -d, --destdir destination
              Set the destination directory to destination.  The default
              destination 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
              example, 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
       transformation 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
       characters, expressed as a standard POSIX regular expression: [a-z]|[A-
       Z]|[0-9]|_| |+|-|*|/.  This is the set which is guaranteed to be
       available regardless of code page.

ENVIRONMENT
       ICU_DATA  Specifies the directory containing ICU data. Defaults to
                 ${prefix}/share/icu/50.1.2/.  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.
