If for some reason you do not want Zend Framework library inside
your include_path, there is another option. There are
two special environment variables that zf.php will
utilize to determine the location of your Zend Framework
installation.
The first is ZEND_TOOL_INCLUDE_PATH_PREPEND, which will
prepend the value of this environment variable to the system
(php.ini) include_path before loading the
client.
Alternatively, you might want to use
ZEND_TOOL_INCLUDE_PATH to completely
replace the system include_path
for one that makes sense specifically for the zf
command line tool.
