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