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.

       -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, 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.
