App::Netdisco::Web::Plugin - Netdisco Web UI components
 | 
						|
 | 
						|
=head1 Introduction
 | 
						|
 | 
						|
L<App::Netdisco>'s plugin system allows you more control of what Netdisco
 | 
						|
components are displayed in the web interface. Plugins can be distributed
 | 
						|
independently from Netdisco and are a better alternative to source code
 | 
						|
patches.
 | 
						|
 | 
						|
The following web interface components are implemented as plugins:
