.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
The \f(CW\*(C`Locale::Codes::LangExt\*(C'\fR module provides access to standard codes
used for identifying language extensions, such as those as defined in
the \s-1IANA\s0 language registry.
.PP
Most of the routines take an optional additional argument which
specifies the code set to use. If not specified, the default \s-1IANA\s0
language registry codes will be used.
.SH "SUPPORTED CODE SETS"
.IX Header "SUPPORTED CODE SETS"
There are several different code sets you can use for identifying
language extensions. A code set may be specified using either a name, or a
constant that is automatically exported by this module.
.PP
For example, the two are equivalent:
.PP
.Vb 2
\&   $lext = code2langext(\*(Aqacm\*(Aq,\*(Aqalpha\*(Aq);
\&   $lext = code2langext(\*(Aqacm\*(Aq,LOCALE_LANGEXT_ALPHA);
.Ve
.PP
The codesets currently supported are:
.IP "\fBalpha\fR" 4
.IX Item "alpha"
This is the set of three-letter (lowercase) codes from the \s-1IANA\s0
language registry, such as 'acm' for Mesopotamian Arabic.
.Sp
This is the default code set.
