.SH NAME
Module::Install::Admin \- Author\-side manager for Module::Install
.SH SYNOPSIS
.IX Header "SYNOPSIS"
In a \fBModule::Install\fR extension module:
.PP
.Vb 4
\&    sub extension_method {
\&        my $self = shift;
\&        $self\->admin\->some_method(@args);
\&    }
.Ve
.PP
As an one-liner:
.PP
.Vb 1
\&    % perl "\-MModule::Install::Admin" \-e\*(Aq&some_method(@args);\*(Aq
.Ve
.PP
The two snippets above are really shorthands for
.PP
.Vb 1
\&    $some_obj\->some_method(@args)
.Ve
.PP
where \f(CW$some_obj\fR is the singleton object of a class under the
\&\f(CW\*(C`Module::Install::Admin::*\*(C'\fR namespace that provides the method
\&\f(CW\*(C`some_method\*(C'\fR.  See "METHODS" for a list of built-in methods.
.SH DESCRIPTION
.IX Header "DESCRIPTION"
This module implements the internal mechanism for initializing,
including and managing extensions, and should only be of interest to
extension developers; it is \fInever\fR included under a distribution's
\&\fIinc/\fR directory, nor are any of the \fBModule::Install::Admin::*\fR
extensions.
.PP
For normal usage of \fBModule::Install\fR, please see Module::Install
and "COOKBOOK / EXAMPLES" in Module::Install instead.
.SS Bootstrapping
.IX Subsection "Bootstrapping"
When someone runs a \fIMakefile.PL\fR that has \f(CW\*(C`use inc::Module::Install\*(C'\fR,
and there is no \fIinc/\fR in the current directory, \fBModule::Install\fR
will load this module bootstrap itself, through the steps below:
.IP \(bu 4
First, \fIModule/Install.pm\fR is POD-stripped and copied from \f(CW@INC\fR to
\&\fIinc/\fR.  This should only happen on the author's side, never on the
end-user side.
.IP \(bu 4
Reload \fIinc/Module/Install.pm\fR if the current file is somewhere else.
This ensures that the included version of \fIinc/Module/Install.pm\fR is
always preferred over the installed version.
.IP \(bu 4
Look at \fIinc/Module/Install/*.pm\fR and load all of them.
.IP \(bu 4
Set up a \f(CW\*(C`main::AUTOLOAD\*(C'\fR function to delegate missing function calls
to \f(CW\*(C`Module::Install::Admin::load\*(C'\fR \-\- again, this should only happen
at the author's side.
.IP \(bu 4
Provide a \f(CW\*(C`Module::Install::purge_self\*(C'\fR function for removing included
files under \fIinc/\fR.
