+| DATABASE CONNECTIVITY SETTINGS
+| -------------------------------------------------------------------
+| This file will contain the settings needed to access your database.
+|
+| For complete instructions please consult the 'Database Connection'
+| page of the User Guide.
+|
+| -------------------------------------------------------------------
+| EXPLANATION OF VARIABLES
+| -------------------------------------------------------------------
+|
+| ['dsn'] The full DSN string describe a connection to the database.
+| ['hostname'] The hostname of your database server.
+| ['username'] The username used to connect to the database
+| ['password'] The password used to connect to the database
+| ['database'] The name of the database you want to connect to
+| ['dbdriver'] The database driver. e.g.: mysqli.
+| Currently supported:
+| cubrid, ibase, mssql, mysql, mysqli, oci8,
+| odbc, pdo, postgre, sqlite, sqlite3, sqlsrv
+| ['dbprefix'] You can add an optional prefix, which will be added
+| to the table name when using the Query Builder class
+| ['pconnect'] TRUE/FALSE - Whether to use a persistent connection
+| ['db_debug'] TRUE/FALSE - Whether database errors should be displayed.
+| ['cache_on'] TRUE/FALSE - Enables/disables query caching
+| ['cachedir'] The path to the folder where cache files should be stored
+| ['char_set'] The character set used in communicating with the database
+| ['dbcollat'] The character collation used in communicating with the database
+| NOTE: For MySQL and MySQLi databases, this setting is only used
+| as a backup if your server is running PHP < 5.2.3 or MySQL < 5.0.7
+| (and in table creation queries made with DB Forge).
+| There is an incompatibility in PHP with mysql_real_escape_string() which
+| can make your site vulnerable to SQL injection if you are using a
+| multi-byte character set and are running versions lower than these.
+| Sites using Latin-1 or UTF-8 database character set and collation are unaffected.
+| ['swap_pre'] A default table prefix that should be swapped with the dbprefix
+| ['encrypt'] Whether or not to use an encrypted connection.
+|
+| 'mysql' (deprecated), 'sqlsrv' and 'pdo/sqlsrv' drivers accept TRUE/FALSE
+| 'mysqli' and 'pdo/mysql' drivers accept an array with the following options:
+|
+| 'ssl_key' - Path to the private key file
+| 'ssl_cert' - Path to the public key certificate file
+| 'ssl_ca' - Path to the certificate authority file
+| 'ssl_capath' - Path to a directory containing trusted CA certificates in PEM format
+| 'ssl_cipher' - List of *allowed* ciphers to be used for the encryption, separated by colons (':')
+| 'ssl_verify' - TRUE/FALSE; Whether verify the server certificate or not
+|
+| ['compress'] Whether or not to use client compression (MySQL only)
+| ['stricton'] TRUE/FALSE - forces 'Strict Mode' connections
+| - good for ensuring strict SQL while developing
+| ['ssl_options'] Used to set various SSL options that can be used when making SSL connections.
+| ['failover'] array - A array with 0 or more data for connections if the main should fail.
+| ['save_queries'] TRUE/FALSE - Whether to "save" all executed queries.
+| NOTE: Disabling this will also effectively disable both
+| $this->db->last_query() and profiling of DB queries.
+| When you run a query, with this setting set to TRUE (default),
+| CodeIgniter will store the SQL statement for debugging purposes.
+| However, this may cause high memory usage, especially if you run
+| a lot of SQL queries ... disable this to avoid that problem.
+|
+| The $active_group variable lets you choose which connection group to
+| make active. By default there is only one group (the 'default' group).
+|
+| The $query_builder variables lets you determine whether or not to load
+| the query builder class.
+*/
+$active_group = 'default';
+$query_builder = TRUE;
+
+$db['default'] = array(
+ 'dsn' => '',
+ 'hostname' => 'localhost',
+ 'username' => '',
+ 'password' => '',

+| URI ROUTING
+| -------------------------------------------------------------------------
+| This file lets you re-map URI requests to specific controller functions.
+|
+| Typically there is a one-to-one relationship between a URL string
+| and its corresponding controller class/method. The segments in a
+| URL normally follow this pattern:
+|
+| example.com/class/method/id/
+|
+| In some instances, however, you may want to remap this relationship
+| so that a different class/function is called than the one
+| corresponding to the URL.
+|
+| Please see the user guide for complete details:
+|
+| https://codeigniter.com/userguide3/general/routing.html
+|
+| -------------------------------------------------------------------------
+| RESERVED ROUTES
+| -------------------------------------------------------------------------
+|
+| There are three reserved routes:
+|
+| $route['default_controller'] = 'welcome';
+|
+| This route indicates which controller class should be loaded if the
+| URI contains no data. In the above example, the "welcome" class
+| would be loaded.
+|
+| $route['404_override'] = 'errors/page_missing';
+|
+| This route will tell the Router which controller/method to use if those
+| provided in the URL cannot be matched to a valid route.
+|
+| $route['translate_uri_dashes'] = FALSE;
+|
+| This is not exactly a route, but allows you to automatically route
+| controller and method names that contain dashes. '-' isn't a valid
+| class or method name character, so it requires translation.
+| When you set this option to TRUE, it will replace ALL dashes in the
+| controller and method URI segments.
+|
+| Examples: my-controller/index -> my_controller/index
+| my-controller/my-method -> my_controller/my_method

+###################
+What is CodeIgniter
+###################
+
+CodeIgniter is an Application Development Framework - a toolkit - for people
+who build web sites using PHP. Its goal is to enable you to develop projects
+much faster than you could if you were writing code from scratch, by providing
+a rich set of libraries for commonly needed tasks, as well as a simple
+interface and logical structure to access these libraries. CodeIgniter lets
+you creatively focus on your project by minimizing the amount of code needed
+for a given task.
+
+*******************
+Release Information
+*******************
+
+This repo contains in-development code for future releases. To download the
+latest stable release please visit the `CodeIgniter Downloads
+<https://codeigniter.com/download>`_ page.
+
+**************************
+Changelog and New Features
+**************************
+
+You can find a list of all changes for each release in the `user
+guide change log <https://github.com/bcit-ci/CodeIgniter/blob/develop/user_guide_src/source/changelog.rst>`_.
+
+*******************
+Server Requirements
+*******************
+
+PHP version 5.6 or newer is recommended.
+
+It should work on 5.3.7 as well, but we strongly advise you NOT to run
+such old versions of PHP, because of potential security and performance
+issues, as well as missing features.
+
+************
+Installation
+************
+
+Please see the `installation section <https://codeigniter.com/userguide3/installation/index.html>`_
+of the CodeIgniter User Guide.
