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 /usr/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.
