.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \f(CW\*(C`Locale::Language\*(C'\fR module provides access to standard codes used
for identifying languages, such as those as defined in \s-1ISO\s0 639.
.PP
Most of the routines take an optional additional argument which
specifies the code set to use. If not specified, the default \s-1ISO\s0
639 two-letter codes will be used.
.SH "SUPPORTED CODE SETS"
.IX Header "SUPPORTED CODE SETS"
There are several different code sets you can use for identifying
languages. The ones currently supported are:
.IP "\fBalpha\-2\fR" 4
.IX Item "alpha-2"
This is the set of two-letter (lowercase) codes from \s-1ISO\s0 639, such
as 'he' for Hebrew.
.Sp
This code set is identified with the symbol \f(CW\*(C`LOCALE_LANG_ALPHA_2\*(C'\fR.
.Sp
This is the default code set.
.IP "\fBalpha\-3\fR" 4
.IX Item "alpha-3"
This is the set of three-letter (lowercase) bibliographic codes from
\&\s-1ISO\s0 639, such as 'heb' for Hebrew.
.Sp
This code set is identified with the symbol \f(CW\*(C`LOCALE_LANG_ALPHA_3\*(C'\fR.
.IP "\fBterm\fR" 4
.IX Item "term"
This is the set of three-letter (lowercase) terminologic codes from
\&\s-1ISO\s0 639.
.Sp
This code set is identified with the symbol \f(CW\*(C`LOCALE_LANG_TERM\*(C'\fR.
