       iconvconfig - create iconv module configuration cache

       iconvconfig [options] [directory]...

       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  addi-
       tion  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 envi-
       ronment variable GCONV_PATH is not set.

              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

              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

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

       Zero on success, non-zero on errors.

              Usual default gconv module path.

              Usual system default gconv module configuration file.
