=head1 NAME

Convos - Multiuser IRC proxy with web interface

=head1 VERSION

0.8604

=head1 DESCRIPTION

Convos is to a multi-user IRC Proxy, that also provides a easy to use Web
interface. Feature list:

=over 4

=item * Always online

The backend server will keep you logged in and logs all the activity
in your archive.

=item * Archive

All chats will be logged and indexed, which allow you to search in
earlier conversations.

=item * Avatars

The chat contains profile pictures which can be retrieved from Facebook
or from gravatar.com.

=item * Include external resources

Links to images and video will be displayed inline. No need to click on
the link to view the data.

=back

=head2 Architecture principles

=over 4

=item * Keep the JS simple and manageable

=item * Use Redis to manage state / publish subscribe

=item * Bootstrap-based user interface

=back

=head1 RUNNING CONVOS

Convos has sane defaults so after installing L you should be
able to just run it:

  # Install
  $ cpanm Convos
  # Run it
  $ convos daemon --listen http://*:8080

The steps above will install and run Convos in a single process. This is a
very quick way to get started, but we incourage to run Convos as one backend
and one frontend:

  # Start the backend first
  $ convos backend start

  # Then start the frontend
  $ convos daemon --listen http://*:8080

This allow you to upgrade and restart the frontend, without having to
reconnect to the IRC servers.

See L for more details.

=head1 CUSTOM TEMPLATES

Some parts of the Convos templates can include custom content. Example:

  # Create a directory where you can store the templates
  $ mkdir -p custom-convos/vendor

  # Edit the template you want to customize
  $ $EDITOR custom-convos/vendor/login_footer.html.ep

  # Start convos with CONVOS_TEMPLATES set. Without /vendor at the end
  $ CONVOS_TEMPLATES=$PWD/custom-convos convos daemon --listen http://*:5000

Any changes to the templates require the server to restart.

The templates that can be customized are:

=over 4

=item * vendor/login_footer.html.ep

This template will be included below the form on the C page.

=item * vendor/register_footer.html.ep

This template will be included below the form on the C page.

=item * vendor/wizard.html.ep

This template will be included below the form on the C page that a
new visitor sees after registering.
