# ExtUtils::Config::MakeMaker(3pm)

A ExtUtils::Config compatible wrapper for ExtUtils::MakeMaker's configuration.

## NAME

ExtUtils::Config::MakeMaker - A ExtUtils::Config compatible wrapper for ExtUtils::MakeMaker's configuration.

## VERSION

version 0.010

## SYNOPSIS

```
 my $config = ExtUtils::Config::MakeMaker->new($makemaker);
```

## DESCRIPTION

This object wraps ExtUtils::MakeMaker's idea of configuration in an ExtUtils::Config compatible interface. That means that if you pass a configuration argument to or in Makefile.PL (e.g. `"OPTIMIZE=-O3"`) it will show up in the config object (e.g. `"$config-"`get('optimize')\>.

## METHODS

### new($makemaker)

This creates a new `"ExtUtils::Config::MakeMaker"` object from a MakeMaker object.

### get($key)

Get the value of `$key`. If not overridden it will return the value in `%Config`.

### exists($key)

Tests for the existence of `$key`.

### values\_set()

Get a hashref of all overridden values.

### all\_config()

Get a hashref of the complete configuration, including overrides.

### serialize()

This method serializes the object to some kind of string. This can be useful for various caching purposes.

### materialize()

This turns this object into an actual `"ExtUtils::Config"` object.

### but(%config)

This returns a `"ExtUtils::Config"` object based on the current one but with the given entries overriden. If any value is `"undef"` it will revert to the official `%Config` value instead.
