NAME
       Package::Util::Lite - Package-related utilities

VERSION
       This document describes version 0.001 of	Package::Util::Lite (from Perl
       distribution Package-Util-Lite),	released on 2019-01-06.

SYNOPSIS
	use Package::Util::Lite	qw(
	    package_exists
	    list_subpackages
	);

	print "Package Foo::Bar	exists"	if package_exists("Foo::Bar");

	my @subpkg    =	list_subpackages("Foo::Bar");
	my @allsubpkg =	list_subpackages("Foo::Bar", 1); # recursive

DESCRIPTION
       This module provides package-related utilities. You should check
       Package::Stash first, then here.

FUNCTIONS
   package_exists
       Usage:

	package_exists($name) => bool

       Return true if package "exists".	By "exists", it	means that the package
       has been	defined	by "package" statement or some entries have been
       created in the symbol table (e.g. "$Foo::var = 1;" will make the	"Foo"
       package "exist").

       This function can be used e.g. for checking before aliasing one package
       to another. Or to casually check	whether	a module has been loaded.

   list_subpackages($name[, $recursive]) => @res
       List subpackages, e.g.:

	(
	    "Foo::Bar::Baz",
	    "Foo::Bar::Qux",
	    ...
	)

       If $recursive is	true, will also	list subpackages of subpackages, and
       so on.
