+=head1 NAME
+
+Catalyst::Plugin::Static::Simple - Make serving static pages painless.
+
+=head1 SYNOPSIS
+
+ use Catalyst;
+ MyApp->setup( qw/Static::Simple/ );
+
+=head1 DESCRIPTION
+
+The Static::Simple plugin is designed to make serving static content in your
+application during development quick and easy, without requiring a single
+line of code from you.
+
+It will detect static files used in your application by looking for file
+extensions in the URI. By default, you can simply load this plugin and it
+will immediately begin serving your static files with the correct MIME type.
+The light-weight MIME::Types module is used to map file extensions to
+IANA-registered MIME types.
+
+Note that actions mapped to paths using periods (.) will still operate
+properly.
+
+You may further tweak the operation by adding configuration options, described
+below.
+
+=head1 ADVANCED CONFIGURATION
+
+Configuration is completely optional and is specified within
+MyApp->config->{static}. If you use any of these options, the module will
+probably feel less "simple" to you!
+
+=head2 Aborting request logging
+
+Since Catalyst 5.50, there has been added support for dropping logging for a
+request. This is enabled by default for static files, as static requests tend
+to clutter the log output. However, if you want logging of static requests,
+you can enable it by setting MyApp->config->{static}->{no_logs} to 0.
+
+=head2 Forcing directories into static mode
+
+Define a list of top-level directories beneath your 'root' directory that
+should always be served in static mode. Regular expressions may be
+specified using qr//.
+
+ MyApp->config->{static}->{dirs} = [
+ 'static',
+ qr/^(images|css)/,
+ ];
+
+=head2 Including additional directories
+
+You may specify a list of directories in which to search for your static
+files. The directories will be searched in order and will return the first
+file found. Note that your root directory is B<not> automatically added to
+the search path when you specify an include_path. You should use
+MyApp->config->{root} to add it.
+
+ MyApp->config->{static}->{include_path} = [
+ '/path/to/overlay',
+ \&incpath_generator,
+ MyApp->config->{root}
+ ];
+
+With the above setting, a request for the file /images/logo.jpg will search
+for the following files, returning the first one found:
+
+ /path/to/overlay/images/logo.jpg
+ /dynamic/path/images/logo.jpg
+ /your/app/home/root/images/logo.jpg
+
+The include path can contain a subroutine reference to dynamically return a
+list of available directories. This method will receive the $c object as a
+parameter and should return a reference to a list of directories. Errors can
+be reported using die(). This method will be called every time a file is
+requested that appears to be a static file (i.e. it has an extension).
+
+For example:
+
+ sub incpath_generator {
+ my $c = shift;
+
+ if ( $c->session->{customer_dir} ) {
+ return [ $c->session->{customer_dir} ];
+ } else {
+ die "No customer dir defined.";
+ }
+ }
+
+=head2 Ignoring certain types of files
+
+There are some file types you may not wish to serve as static files. Most
+important in this category are your raw template files. By default, files
+with the extensions tt, tt2, html, and xhtml will be ignored by Static::Simple
+in the interest of security. If you wish to define your own extensions to
+ignore, use the ignore_extensions option:
+
+ MyApp->config->{static}->{ignore_extensions} = [ qw/tt tt2 html xhtml/ ];
+
+=head2 Ignoring entire directories
+
+To prevent an entire directory from being served statically, you can use the
+ignore_dirs option. This option contains a list of relative directory paths
+to ignore. If using include_path, the path will be checked against every
+included path.
+
+ MyApp->config->{static}->{ignore_dirs} = [ qw/tmpl css/ ];
+
+For example, if combined with the above include_path setting, this
+ignore_dirs value will ignore the following directories if they exist:
+
+ /path/to/overlay/tmpl
+ /path/to/overlay/css
+ /dynamic/path/tmpl
+ /dynamic/path/css
+ /your/app/home/root/tmpl
+ /your/app/home/root/css
+
+=head2 Custom MIME types
+
+To override or add to the default MIME types set by the MIME::Types module,
+you may enter your own extension to MIME type mapping.
+
+ MyApp->config->{static}->{mime_types} = {
+ jpg => 'image/jpg',
+ png => 'image/png',
+ };
+
+=head2 Bypassing other plugins
+
+This plugin checks for a static file in the prepare_action stage. If the
+request is for a static file, it will bypass all remaining prepare_action
+steps. This means that by placing Static::Simple before all other plugins,
+they will not execute when a static file is found. This can be helpful by
+skipping session cookie checks for example. Or, if you want some plugins
+to run even on static files, list them before Static::Simple.
+
+Currently, work done by plugins in any other prepare method will execute
+normally.
+
+=head2 Debugging information
+
+Enable additional debugging information printed in the Catalyst log. This
+is automatically enabled when running Catalyst in -Debug mode.
+
+ MyApp->config->{static}->{debug} = 1;
+
+=head1 USING WITH APACHE
+
+While Static::Simple will work just fine serving files through Catalyst in
+mod_perl, for increased performance, you may wish to have Apache handle the
+serving of your static files. To do this, simply use a dedicated directory
+for your static files and configure an Apache Location block for that
+directory. This approach is recommended for production installations.
