# ExtUtils::Config(3pm)

A wrapper for perl's configuration

## NAME

ExtUtils::Config - A wrapper for perl's configuration

## VERSION

version 0.010

## SYNOPSIS

```
 my $config = ExtUtils::Config->new();
 $config->get('installsitelib');
```

## DESCRIPTION

ExtUtils::Config is an abstraction around the `%Config` hash. By itself it is not a particularly interesting module by any measure, however it ties together a family of modern toolchain modules.

## METHODS

### new(\\%config)

Create a new ExtUtils::Config object. The values in `"\%config"` are used to initialize the 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`.

### but(\\%keys)

This creates a new `"ExtUtils::Config"` object based on the current one, but with the values in `%keys` replacing the current values. Any undefined value means it will be removed from the overriden set.

### 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.
