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.
