Welcome to the interactive Doctrine Compiler 0.0.1 (Beta).
|
||||
|

WARNING: You're on your own - this script modifies your
|
||||
filesystem and has not been tested on Windows (yet).

<?php
|

Usage:
|
||||
<?php echo $argv[0]; ?> [path]
|
||||
|
||||
[path] is the path to Doctrine's lib directory. This
|
||||
is normally the directory containing the core
|
||||
Doctrine class, 'Doctrine.php'.
|

|
||||
While the program is running:
|
||||
|
||||
Default responses to questions are capitalized. Just
|
||||
hit enter to provide a question's default response.
|
||||
|
||||
You can quit the program at any time by pressing 'q'.
