+
+Youri::Bugzilla - Youri Bugzilla interface
+
+=head1 SYNOPSIS
+
+    use Youri::Bugzilla;

+
+=head1 DESCRIPTION
+
+This module implement a database-level Bugzilla interface for managing packages.
+
+The legacy Bugzilla database model is mapped this way:
+

+
+=item *
+
+a maintainer is a user
+
+=item *
+
+a package is a product
+
+=item *
+
+each package has two pseudo components "program" and "package", owned by the package maintainer

+=head1 NAME

+Youri::Config - Youri configuration handler
+
+=head1 SYNOPSIS
+
+    use Youri::Config;
+
+    my $config = Youri::Config->new(
+        command_spec => [
+            'help|h!',

+        file_spec => [
+            'foo=s',

+        file_name   => 'app.conf',
+        caller      => $0,
+    );
+
+    # get configuration directive
+    my $foo = $config->get('foo');
+
+    # get configuration section
+    my %bar = $config->get_section('bar');
+
+=head1 DESCRIPTION
+
+This class handle configuration for all YOURI tools.
+
+It uses distinct command line and config files specification, but merges the
+two inputs transparently, command line directives overriding config file
+directives with the same name.
+
+Given directories are scanned for a file with given name, and only the first
+one found is used. If B<--config> argument is given on command line, no
+scanning occurs. If no readable file is found, an exception is thrown.
+
+==head1 FORMAT
+
+The file format used is the one from AppConfig, with the additional ability to
+use YAML. Here is an exemple configuration file:
+
+    [updates]
+    class    = Youri::Check::Check::Updates
+    grabbers = <<EOF
+    --- #YAML:1.0
+    debian:
+        class: Youri::Check::Check::Updates::Debian
+        aliases:
+            fuse: ~
+    cpan:
+        class: Youri::Check::Check::Updates::CPAN
+    fedora:
+        class: Youri::Check::Check::Updates::Fedora
+    gentoo:
+        class: Youri::Check::Check::Updates::Gentoo
+    freshmeat:
+        class: Youri::Check::Check::Updates::Freshmeat
+        aliases:
+            fuse: fuse-emulator
+    EOF
+
+As a side-effect of using YAML, the use of character '~' anywhere is prohibited.
+Use ${HOME} instead.
