       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.
