NAME
       Test::Vars - Detects unused variables

VERSION
       This document describes Test::Vars version 0.005.

SYNOPSIS
	   use Test::Vars;

	   all_vars_ok(); # check libs in MANIFEST

DESCRIPTION
       Test::Vars finds unused variables in order to keep the source code tidy.

INTERFACE
   Exported
       all_vars_ok(%args)

       Tests libraries in your distribution with %args.

       libraries are collected from the MANIFEST file.

       If you want to ignore variables, for example $foo, you can tell it to the test routines:

       "ignore_vars => { '$foo' => 1 }"
       "ignore_vars => [qw($foo)]"
       "ignore_if => sub{ $_ eq '$foo' }"

       Note that $self will be ignored by default unless you pass explicitly "{ '$self' => 0 }" to "ignore_vars".

       vars_ok($lib, %args)

       Tests $lib with %args.

       See "all_vars_ok".

MECHANISM
       "Test::Vars" is similar to a part of "Test::Perl::Critic",but the mechanism is different.

       While "Perl::Critic", the backend of "Test::Perl::Critic", scans the source code as texts, this modules scans the compiled opcode (or AST:
       abstract syntax tree) using the "B" module. See also "B" and its submodules.

CONFIGURATION
       "TEST_VERBOSE = 1 | 2 " shows the way this module works.
