Locale::Codes::Script - standard codes for script identification

=head1 SYNOPSIS

   use Locale::Codes::Script;

   $script  = code2script('phnx');                     # 'Phoenician'
   $code    = script2code('Phoenician');               # 'Phnx'
   $code    = script2code('Phoenician',
                          LOCALE_CODE_NUMERIC);        # 115

   @codes   = all_script_codes();
   @scripts = all_script_names();

=head1 DESCRIPTION

The C<Locale::Codes::Script> module provides access to standards codes used
for identifying scripts, such as those defined in ISO 15924.

Most of the routines take an optional additional argument which
specifies the code set to use. If not specified, the default ISO
15924 four-letter codes will be used.

=head1 SUPPORTED CODE SETS

There are several different code sets you can use for identifying
scripts. A code set may be specified using either a name, or a
constant that is automatically exported by this module.

For example, the two are equivalent:

   $script = code2script('phnx','alpha');
   $script = code2script('phnx',LOCALE_SCRIPT_ALPHA);

The codesets currently supported are:

=over 4

=item B<alpha, LOCALE_SCRIPT_ALPHA>

This is a set of four-letter (capitalized) codes from ISO 15924
such as 'Phnx' for Phoenician.  It also includes additions to this
set included in the IANA language registry.

The Zxxx, Zyyy, and Zzzz codes are not used.

This is the default code set.

=item B<num, LOCALE_SCRIPT_NUMERIC>

This is a set of three-digit numeric codes from ISO 15924 such as 115
for Phoenician.
