NAME

Boucherot::ModuleManager - A set of instance of Boucherot's Modules

SYNOPSIS

        use Boucherot::ModuleManager;
        my $mm=new Boucherot::ModuleManager;

        # ...

        # Foo::Bar is "ModuleManager" compatible.
        my $module=new Foo::Bar;

        $mm->add($module);

        printf "The module unique ID is %s\n",$module->mid;

        my $mid=$module->mid;

        $module2=$mm->get($mid);

        # Here $module2 eq $module

DESCRIPTION

This class is a module manager.

All instances of modules that are registred to the ModuleManager must be used only by storing the module id, and not by storing a reference on the module.

That mean, by removing the module from the module manager, the instance is destroyed.

The ModuleManager don't know the classes. It only know they can ``mid'' (as method)
