NAME
       iconvconfig - create iconv module configuration cache

SYNOPSIS
       iconvconfig [options] [directory]...

DESCRIPTION
       The  iconv(3)  function internally uses gconv modules to convert to and
       from a character set.  A configuration file is used  to	determine  the
       needed modules for a conversion.	 Loading and parsing such a configura-
       tion file would slow down programs that	use  iconv(3),	so  a  caching
       mechanism is employed.

       The  iconvconfig	 program  reads	 iconv	module configuration files and
       writes a fast-loading gconv module configuration cache file.

       In addition to the system provided gconv modules, the user can  specify
       custom	gconv	module	 directories  with  the	 environment  variable
       GCONV_PATH.  However, iconv module configuration caching is  used  only
       when the environment variable GCONV_PATH is not set.

OPTIONS
       --nostdlib
	      Do  not  search  the  system  default  gconv directory, only the
	      directories provided on the command line.

       -o outputfile, --output=outputfile
	      Use outputfile for output instead of the	system	default	 cache
	      location.

       --prefix=pathname
	      Set  the	prefix	to  be prepended to the system pathnames.  See
	      FILES, below.  By default, the prefix  is	 empty.	  Setting  the
	      prefix to foo, the gconv module configuration would be read from
	      foo/usr/lib/gconv/gconv-modules and the cache would  be  written
	      to foo/usr/lib/gconv/gconv-modules.cache.

       -?, --help
	      Print a usage summary and exit.

       --usage
	      Print a short usage summary and exit.

       -V, --version
	      Print  the  version  number, license, and disclaimer of warranty
	      for iconv.

EXIT STATUS
       Zero on success, non-zero on errors.

FILES
       /usr/lib/gconv
	      Usual default gconv module path.

       /usr/lib/gconv/gconv-modules
	      Usual system default gconv module configuration file.

       /usr/lib/gconv/gconv-modules.cache
	      Usual system gconv module configuration cache.
