.SH Name 
intro \- introduction to international subroutines
.SH Description 
.NXR "international subroutines" "introduction"
.NXR "subroutines" "international" 
The internationalization package provides a convenient method
of writing or converting applications so that they can operate
in the application user's natural language.
.PP
The package consists of the following:
.IP \(bu
Tools for the creation and modification of message catalogs
.IP \(bu
An international function library, which is called 
.I libi
.IP \(bu
A set of international functions available in the C library,
.I libc
.IP \(bu
An international compiler that creates language support databases
from special source files
.IP \(bu
An announcement and initialization mechanism
.IP \(bu
A utility for converting data from one codeset to another codeset
.PP
When you use international library functions in a C program,
compile it with the
.PN \-li
option to include \fIlibi,\fP as shown:
.EX 0
% cc \-o prog prog.c \-li
.EE
Some of the international functions are available in the
standard C library.
You need not compile with the 
.PN \-li 
option if you use only those functions.  The functions that are available
in the standard C library are 
.PN setlocale ,
.PN strftime ,
.PN strxfrm ,
and
.PN strcoll .
