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 envi‐
       ronment	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.
