LedgerSMB::Locale - Locale handling class for LedgerSMB

=head1 SYNOPSIS

Locale support module for LedgerSMB.  Uses Locale::Maketext::Lexicon as a base.

=head1 METHODS

=over

=item get_handle ($language_code)

Returns a locale handle for accessing the other methods.  Inherited from
Locale::Maketext.

=item marktext ($string)

Identity function. Allows text to me marked for translation so that it
will be picked by the PO scanner. The actual translation has to be done
in the calling module when the page is prepared.
Note: This isn't a method but a utility function.

=item text ($string, @params)

Returns the translation for the given string.  Use this method with a litteral
string argument to make sure it's included in the translation lexicon.

To request translation of a non-litteral string (e.g. function return value),
call the maketext() method.

=item maketext ($string, @params)

Returns the translation for the given string.  The string position argument
won't be included in the translation lexicon.  Use this function to translate
a string held in a variable, or returned from a function.

=item date ($myconfig, $date, $longformat)

Returns the given date after formatting it.  $longformat is a ternary flag that
determines how the date is formatted.  If $longformat is true, the date will be
given in the form of "_('September') 23 2007".  If $longformat is false but
defined, the date will be in the form of "_('Sep') 23 2007" unless the date is
given in the form 'yyyy.mm.dd', in which case it is returned as-is.  If
$longformat is not defined, the date will be output in the format specified by
$myconfig->{dateformat}.
