=head2 -Engine
Forces Catalyst to use a specific engine. Omit the
the name will be replaced with underscores, e.g. MyApp::Web should use
MYAPP_WEB_HOME. If both variables are set, the MYAPP_HOME one will be used.
+If none of these are set, Catalyst will attempt to automatically detect the
+home directory. If you are working in a development envirnoment, Catalyst
+will try and find the directory containing either Makefile.PL, Build.PL or
+dist.ini. If the application has been installed into the system (i.e.
+you have done C<make install>), then Catalyst will use the path to your
+application module, without the .pm extension (ie, /foo/MyApp if your
+application was installed at /foo/MyApp.pm)

Note that L<< forward|/"$c->forward( $action [, \@arguments ] )" >> implies
an C<< eval { } >> around the call (actually
need to do something like:
$c->forward('foo');
- die $c->error if $c->error;
+ die join "\n", @{ $c->error } if @{ $c->error };
Or make sure to always return true values from your actions and write
your code like this:
$c->forward('foo') || return;
+Another note is that C<< $c->forward >> always returns a scalar because it
+actually returns $c->state which operates in a scalar context.
+Thus, something like:
+
+ return @array;
+
+in an action that is forwarded to is going to return a scalar,
+i.e. how many items are in that array, which is probably not what you want.
+If you need to return an array then return a reference to it,
+or stash it like so:
+
+ $c->stash->{array} = \@array;
+
+and access it from the stash.

+=head1 CONFIGURATION
+
+There are a number of 'base' config variables which can be set:
+
+=over
+
+=item *
+
+C<default_model> - The default model picked if you say C<< $c->model >>. See L<< /$c->model($name) >>.
+
+=item *
+
+C<default_view> - The default view to be rendered or returned when C<< $c->view >> is called. See L<< /$c->view($name) >>.
+
+=item *
+
+C<disable_component_resolution_regex_fallback> - Turns
+off the deprecated component resolution functionality so
+that if any of the component methods (e.g. C<< $c->controller('Foo') >>)
+are called then regex search will not be attempted on string values and
+instead C<undef> will be returned.
+
+=item *
+
+C<home> - The application home directory. In an uninstalled application,
+this is the top level application directory. In an installed application,
+this will be the directory containing C<< MyApp.pm >>.
+
+=item *
+
+C<ignore_frontend_proxy> - See L</PROXY SUPPORT>
+
+=item *
+
+C<name> - The name of the application in debug messages and the debug and
+welcome screens
+
+=item *
+
+C<parse_on_demand> - The request body (for example file uploads) will not be parsed
+until it is accessed. This allows you to (for example) check authentication (and reject
+the upload) before actually recieving all the data. See L</ON-DEMAND PARSER>
+
+=item *
+
+C<root> - The root directory for templates. Usually this is just a
+subdirectory of the home directory, but you can set it to change the
+templates to a different directory.
+
+=item *
+
+C<search_extra> - Array reference passed to Module::Pluggable to for additional
+namespaces from which components will be loaded (and constructed and stored in
+C<< $c->components >>).
+
+=item *
+
+C<show_internal_actions> - If true, causes internal actions such as C<< _DISPATCH >>
+to be shown in hit debug tables in the test server.
+
+=item *
+
+C<using_frontend_proxy> - See L</PROXY SUPPORT>.
+
+=back
+
=head1 INTERNAL ACTIONS
Catalyst uses internal actions like C<_DISPATCH>, C<_BEGIN>, C<_AUTO>,
MyApp->config(show_internal_actions => 1);
-=head1 CASE SENSITIVITY
-
-By default Catalyst is not case sensitive, so C<MyApp::C::FOO::Bar> is
-mapped to C</foo/bar>. You can activate case sensitivity with a config
-parameter.
-
- MyApp->config(case_sensitive => 1);
-
-This causes C<MyApp::C::Foo::Bar> to map to C</Foo/Bar>.

=head1 ON-DEMAND PARSER
The request body is usually parsed at the beginning of a request,
