Not exactly the same i guess, i think this will rebuild package A and all its dependencies (we are going "down" on dependencies).

The point of this script is to rebuild package A and all those who depends on it (we are going "up" on dependencies).

Based on previous work done on the reverse-dependencies (make <pkg>-show-rdepends), this has been turned in recursive-reverse-dependencies.
