 410 ***************************** ZF ERROR ********************************
 411 In order to run the zf command, you need to ensure that Zend Framework
 412 is inside your include_path.  There are a variety of ways that you can
 413 ensure that this zf command line tool knows where the Zend Framework
 414 library is on your system, but not all of them can be described here.
 415
 416 The easiest way to get the zf command running is to give it the include
 417 path via an environment variable ZEND_TOOL_INCLUDE_PATH or
 418 ZEND_TOOL_INCLUDE_PATH_PREPEND with the proper include path to use,
 419 then run the command "zf --setup".  This command is designed to create
 420 a storage location for your user, as well as create the zf.ini file
 421 that the zf command will consult in order to run properly on your
 422 system.
 423
 424 Example you would run:
 425
 426 $ ZEND_TOOL_INCLUDE_PATH=/path/to/library zf --setup
 427
