121 "MyApp::Model::Something" the "name" attribute should be "Something".

149 Converting your existing config to Config::General format
150 As of Catalyst::Devel 1.07, a newly created application will use
151 Config::General for configuration. If you wish to convert your existing
152 config, run the following one-liner (replacing MyApp with your app's
153 name):
154
155 perl -Ilib -MMyApp -MConfig::General -e 'Config::General->new->save_file("myapp.conf", MyApp->config);'
156
157 Using UTF-8 strings in a Config::General file
158 If you have UTF-8 strings in your Config::General-based config file,
159 you should add the following config information to MyApp.pm:
160
161 __PACKAGE__->config( 'Plugin::ConfigLoader' => {
162 driver => {
163 'General' => { -UTF8 => 1 },
164 }
165 } );
166
167 Using a local configuration file
168 When ConfigLoader reads configurations, it starts by reading the
169 configuration file for "myapp" with one of the supported extensions as
170 listed above.
171
172 For example, A Config::General config file is myapp.conf.
173
174 If a configuration file called "myapp_local" exists with one of the
175 supported file extensions, it will also be read, and values from that
176 file will override values from the main config file.
177
178 A Config::General local configuration file would be called
179 myapp_local.conf.
180
181 The "local" suffix can be changed. See "get_config_local_suffix" in
182 Catalyst::Plugin::ConfigLoader for the details of how.
183
184 This is useful because it allows different people or environments to
185 have different configuration files. A project with three developers,
186 Tom, Dick, and Harry as well as a production environment can have a
187 myapp_tom.conf, a myapp_dick.conf, a myapp_harry.conf, and a
188 myapp_production.conf.
189
190 Each developer, and the web server, would set the environment variable
191 to load their proper configuration file. All of the configurations can
192 be stored properly in source control.
193
194 If there is no myapp_local.ext (where ".ext" is a supported extension),
195 and the individual configuration files contain something required to
196 start the application, such as the Model's data source definition, the
197 applicaton won't start unless the environment variable is set properly.
