// This script can be used to automatically glue all the .php files of Predis
|
| 15 |
|
|
// into a single monolithic script file that can be used without an autoloader,
|
| 16 |
|
|
// just like the other previous versions of the library.
|
| 17 |
|
|
//
|
| 18 |
|
|
// Much of its complexity is due to the fact that we cannot simply join PHP
|
| 19 |
|
|
// files, but namespaces and classes definitions must follow a precise order
|
| 20 |
|
|
// when dealing with subclassing and inheritance.
|
| 21 |
|
|
//
|
| 22 |
|
|
// The current implementation is pretty na?ve, but it should do for now.
