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
       configuration 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.

       --output=outputfile
       -o 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.

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

EXIT STATUS
       Zero on success, nonzero 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.

       Depending on the architecture, the above files may instead be located
       at directories with the path prefix /usr/lib64.
