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
   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.


          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.
