+=head1 NAME
+
+Locale::Maketext::Simple - Simple interface to Locale::Maketext::Lexicon
+
+=head1 VERSION
+
+This document describes version 0.18 of Locale::Maketext::Simple,
+released Septermber 8, 2006.
+
+=head1 SYNOPSIS
+
+Minimal setup (looks for F<auto/Foo/*.po> and F<auto/Foo/*.mo>):
+
+ package Foo;
+ use Locale::Maketext::Simple; # exports 'loc'
+ loc_lang('fr'); # set language to French
+ sub hello {
+ print loc("Hello, [_1]!", "World");
+ }
+
+More sophisticated example:
+
+ package Foo::Bar;
+ use Locale::Maketext::Simple (
+ Class => 'Foo', # search in auto/Foo/
+ Style => 'gettext', # %1 instead of [_1]
+ Export => 'maketext', # maketext() instead of loc()
+ Subclass => 'L10N', # Foo::L10N instead of Foo::I18N
+ Decode => 1, # decode entries to unicode-strings
+ Encoding => 'locale', # but encode lexicons in current locale
+ # (needs Locale::Maketext::Lexicon 0.36)
+ );
+ sub japh {
+ print maketext("Just another %1 hacker", "Perl");
+ }
+
+=head1 DESCRIPTION
+
+This module is a simple wrapper around B<Locale::Maketext::Lexicon>,
+designed to alleviate the need of creating I<Language Classes> for
+module authors.
+
+If B<Locale::Maketext::Lexicon> is not present, it implements a
+minimal localization function by simply interpolating C<[_1]> with
+the first argument, C<[_2]> with the second, etc. Interpolated
+function like C<[quant,_1]> are treated as C<[_1]>, with the sole
+exception of C<[tense,_1,X]>, which will append C<ing> to C<_1> when
+X is C<present>, or appending C<ed> to <_1> otherwise.
+
+=head1 OPTIONS
+
+All options are passed either via the C<use> statement, or via an
+explicit C<import>.
+
+=head2 Class
+
+By default, B<Locale::Maketext::Simple> draws its source from the
+calling package's F<auto/> directory; you can override this behaviour
+by explicitly specifying another package as C<Class>.
+
+=head2 Path
+
+If your PO and MO files are under a path elsewhere than C<auto/>,
+you may specify it using the C<Path> option.
+
+=head2 Style
+
+By default, this module uses the C<maketext> style of C<[_1]> and
+C<[quant,_1]> for interpolation. Alternatively, you can specify the
+C<gettext> style, which uses C<%1> and C<%quant(%1)> for interpolation.
+
+This option is case-insensitive.
+
+=head2 Export
+
+By default, this module exports a single function, C<loc>, into its
+caller's namespace. You can set it to another name, or set it to
+an empty string to disable exporting.
+
+=head2 Subclass
+
+By default, this module creates an C<::I18N> subclass under the
+caller's package (or the package specified by C<Class>), and stores
+lexicon data in its subclasses. You can assign a name other than
+C<I18N> via this option.
+
+=head2 Decode
+
+If set to a true value, source entries will be converted into
+utf8-strings (available in Perl 5.6.1 or later). This feature
+needs the B<Encode> or B<Encode::compat> module.
+
+=head2 Encoding
+
+Specifies an encoding to store lexicon entries, instead of
+utf8-strings. If set to C<locale>, the encoding from the current
+locale setting is used. Implies a true value for C<Decode>.
