NAME
       Module::Loaded - mark modules as loaded or unloaded

SYNOPSIS
           use Module::Loaded;

           $bool = mark_as_loaded('Foo');   # Foo.pm is now marked as loaded
           $loc  = is_loaded('Foo');        # location of Foo.pm set to the
                                            # loaders location
           eval "require 'Foo'";            # is now a no-op

           $bool = mark_as_unloaded('Foo'); # Foo.pm no longer marked as loaded
           eval "require 'Foo'";            # Will try to find Foo.pm in @INC

DESCRIPTION
       When testing applications, often you find yourself needing to provide functionality in
       your test environment that would usually be provided by external modules. Rather than
       munging the %INC by hand to mark these external modules as loaded, so they are not
       attempted to be loaded by perl, this module offers you a very simple way to mark modules
       as loaded and/or unloaded.

FUNCTIONS
   $bool = mark_as_loaded( PACKAGE );
       Marks the package as loaded to perl. "PACKAGE" can be a bareword or string.

       If the module is already loaded, "mark_as_loaded" will carp about this and tell you from
       where the "PACKAGE" has been loaded already.

   $bool = mark_as_unloaded( PACKAGE );
       Marks the package as unloaded to perl, which is the exact opposite of "mark_as_loaded".
       "PACKAGE" can be a bareword or string.

       If the module is already unloaded, "mark_as_unloaded" will carp about this and tell you
       the "PACKAGE" has been unloaded already.

   $loc = is_loaded( PACKAGE );
       "is_loaded" tells you if "PACKAGE" has been marked as loaded yet.  "PACKAGE" can be a
       bareword or string.

       It returns falls if "PACKAGE" has not been loaded yet and the location from where it is
       said to be loaded on success.
