| 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
