|

* variable contains the string "PHPUnit", the file that $_SERVER['_']
|

* points to is assumed to be the PHPUnit TextUI CLI wrapper script
|
||||
* "phpunit" and the binary set up using #! on that file's first
|
||||
* line of code is assumed to contain the path to the current PHP
|
||||
* interpreter and that will be used.
|
||||
*
|
||||
* 3. When the PHP CLI/CGI binary configured with the PEAR Installer
|
||||
* (php_bin configuration value) is readable, it will be used.
|
||||
*
|

* 4. The current PHP interpreter is assumed to be in the $PATH and
|
||||
* to be invokable through "php".
