# Module::Install::Base(3pm)

Base class for Module::Install extensions

## NAME

Module::Install::Base - Base class for Module::Install extensions

## SYNOPSIS

In a **Module::Install** extension:

```
    use Module::Install::Base ();
    @ISA = qw(Module::Install::Base);
```

## DESCRIPTION

This module provide essential methods for all **Module::Install** extensions, in particular the common constructor `"new"` and method dispatcher `"AUTOLOAD"`.

## METHODS

- new(%args)

  Constructor -- need to preserve at least \_top

- AUTOLOAD

  The main dispatcher - copy extensions if missing

- **\_top()**

  Returns the top-level **Module::Install** object.

- **admin()**

  Returns the `"_top"` object's associated **Module::Install::Admin** object on the first run (i.e. when there was no *inc/* when the program started); on subsequent (user-side) runs, returns a fake admin object with an empty `"AUTOLOAD"` method that does nothing at all.

- **is\_admin()**

  Tells whether this is the first run of the installer (on author's side). That is when there was no *inc/* at program start. True if that's the case. False, otherwise.
