=head1 NAME
Alien::Build::Plugin::Fetch::NetFTP - Plugin for fetching files using Net::FTP
=head1 VERSION
version 2.84
=head1 SYNOPSIS
use alienfile;
share {
start_url 'ftp://ftp.gnu.org/gnu/make';
plugin 'Fetch::NetFTP';
};
=head1 DESCRIPTION
Note: in most case you will want to use L
instead. It picks the appropriate fetch plugin based on your platform and environment.
In some cases you may need to use this plugin directly instead.
This fetch plugin fetches files and directory listings via the C, protocol using
L.
=head1 PROPERTIES
=head2 url
The initial URL to fetch. This may be a directory or the final file.
=head2 ssl
This property is for compatibility with other fetch plugins, but is not used.
=head2 passive
If set to true, try passive mode FIRST. By default it will try an active mode, then
passive mode.
