 | 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 mentioned 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 three main conventions used for determining exit status codes
 | are as follows:
 |
 |    Standard C/C++ Library (stdlibc):
 |       http://www.gnu.org/software/libc/manual/html_node/Exit-Status.html
 |       (This link also contains other GNU-specific conventions)
 |    BSD sysexits.h:
 |       http://www.gsp.com/cgi-bin/man.cgi?section=3&topic=sysexits
 |    Bash scripting:
 |       http://tldp.org/LDP/abs/html/exitcodes.html
