+.TH ICONVCONFIG 8 2014-06-09 "GNU" "Linux System Administration"
+.SH NAME
+iconvconfig \- create iconv module configuration cache
+.SH SYNOPSIS
+.B iconvconfig
+.RI [ options ]
+.RI [ directory ]...
+.SH DESCRIPTION
+The
+.BR iconv(3)
+function internally uses
+.I 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
+.BR iconv(3)
+using programs so a caching mechanism has been introduced.
+
+The
+.B iconvconfig
+program reads iconv module configuration files and writes
+a fastloading gconv module configuration cache file.
+In addition to the system provided gconv modules, user can specify 
+custom gconv module directories with the environment variable
+.BR GCONV_PATH .
+However, iconv module configuration caching is only used when
+the environment variable
+.BR GCONV_PATH
+is not set.
+.SH OPTIONS
+.TP
+.B "\-\-nostdlib"
+Do not search the system default gconv directory,
+only the directories provided on the command line.
+.TP
+.BI \-o " outputfile" ", \-\-output=" outputfile
+Use
+.I outputfile
+for output instead of the system default cache location.
+.TP
+.BI \-\-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
+.IR foo ,
+the gconv module configuration would be read from
+.IR foo/usr/lib/gconv/gconv-modules
+and the cache would be written to
+.IR foo/usr/lib/gconv/gconv-modules.cache .
+.TP
+.B "\-\-help"
+Print a usage summary and exit.
+.TP
+.B "\-\-usage"
+Print a short usage summary and exit.
+.TP
+.B "\-V, \-\-version"
+Print the version number, license, and disclaimer of warranty for
+.BR iconv .
+.SH EXIT STATUS
+Zero on success, non-zero on errors.
+.SH FILES
+.TP
+.I /usr/lib/gconv
+Usual default gconv module path.
+.TP
+.I /usr/lib/gconv/gconv-modules
+Usual default gconv module configuration.
+.TP
+.I /usr/lib/gconv/gconv-modules.cache
+Usual default gconv module configuration cache.
+.SH "SEE ALSO"
+.BR iconv (1),
+.BR iconv (3)
