                          |   | 4 | Trac configuration is done by editing the '''`trac.ini`''' config file, located in `<projectenv>/conf/trac.ini`.  Changes to the configuration are usually reflected immediately, though changes to the `[components]` or `[logging]` sections will require restarting the web server. You may also need to restart the web server after creating a global configuration file when none was previously present. |

                          |   | 8 | In previous versions, the global configuration was by default located in `$prefix/share/trac/conf/trac.ini` or sometimes /etc/trac/trac.ini depending on the distribution. If you're upgrading, you may want to specify that file to inherit from. |

                          |   | 23 | This section is used to enable or disable components provided by plugins, as well as by Trac itself. The component to enable/disable is specified via the name of the option. Whether its enabled is determined by the option value; setting the value to `enabled` or `on` will enable the component, any other value (typically `disabled` or `off`) will disable the component. | 
                  
                          |   | 24 |  | 
                  
                          |   | 25 | The option name is either the fully qualified name of the components or the module/package prefix of the component. The former enables/disables a specific component, while the latter enables/disables any component in the specified package/module. |

                          |   | 27 | Consider the following configuration snippet: |

                          |   | 34 | The first option tells Trac to disable the [wiki:TracReports report module]. The second option instructs Trac to enable all components in the `webadmin` package. Note that the trailing wildcard is required for module/package matching. |

                          |   | 47 | The workflow for tickets is controlled by plugins.  | 
                  
                          |   | 48 | By default, there's only a `ConfigurableTicketWorkflow` component in charge.  | 
                  
                          |   | 49 | That component allows the workflow to be configured via this section in the trac.ini file. |

                          |   | 55 | As the workflow for tickets is now configurable, there can be many ticket states, | 
                  
                          |   | 56 | and simply displaying closed tickets vs. all the others is maybe not appropriate  | 
                  
                          |   | 57 | in all cases. This section enables one to easily create ''groups'' of states  | 
                  
                          |   | 58 | that will be shown in different colors in the milestone progress bar. |

                          |   | 73 | Also, '*' means any status and could be used to associate all remaining |

                          |   | 83 | The TracBrowser for Subversion can interpret the `svn:externals` property of folders out of the box. | 
                  
                          |   | 84 | However, if those externals are ''not'' using the `http:` protocol, or if a link to a different repository browser (such another Trac or [http://www.viewvc.org/ ViewVC]) is desired, then Trac needs to be able to map an external prefix to this other URL. | 
                  
                          |   | 85 |  | 
                  
                          |   | 86 | This mapping is done in the `[svn:externals]` section of the TracIni |
