# ExtUtils::MakeMaker::bytes(3perl)

Version-agnostic bytes.pm

## NAME

ExtUtils::MakeMaker::bytes - Version-agnostic bytes.pm

## SYNOPSIS

```
  use just like bytes.pm
```

## DESCRIPTION

bytes.pm was introduced with 5.6.  This means any code which has 'use bytes' in it won't even compile on 5.5.X.  Since bytes is a lexical pragma and must be used at compile time we can't simply wrap it in a BEGIN { eval 'use bytes' } block.

ExtUtils::MakeMaker::bytes is just a very thin wrapper around bytes which works just like it when bytes.pm exists and everywhere else it does nothing.
