| certain environments (Apache running a separate process for each
| user, PHP under CGI with Apache suEXEC, etc.).  Octal values should
| always be used to set the mode correctly.

| Exit Status Codes
|--------------------------------------------------------------------------
|
| Used to indicate the conditions under which the script is exit()ing.
| While there is no universal standard for error codes, there are some
| broad conventions.  Three such conventions are presented below, for
| those who wish to make use of them.  The CodeIgniter defaults were 
| chosen for the least overlap with these conventions, while still
| leaving room for others to be defined in future versions and user
| applications.  The CodeIgniter values are defined last so you can 
| set them to values used by any of the other conventions, and do so 
| by name instead of value.
