Test::LocalFunctions - Detects unused local functions



# VERSION

This document describes Test::LocalFunctions version 0.06



# SYNOPSIS

    use Test::LocalFunctions;

    # check modules that are listed in MANIFEST
    all_local_functions_ok();

    # you can also specify individual file
    local_functions_ok('/path/to/your/module_or_script');



# DESCRIPTION

Test::LocalFunctions finds unused local functions to clean up the source code.
(Local function means the function which name starts from underscore.)

This module decides back end module automatically. If \`Compiler::Lexer\` has been
installed in target environment, this module will use \`Compiler::Lexer\` as back end.
Elsewise this module will use \`PPI\`.

\`PPI\` is not fast, but \`Compiler::Lexer\` is fast.
So I recommend you to install \`Compiler::Lexer\`.
