=head1 NAME

Alien::Build::Plugin::Fetch::CurlCommand - Plugin for fetching files using curl

=head1 VERSION

version 2.84

=head1 SYNOPSIS

 use alienfile;
 
 share {
   start_url 'https://www.openssl.org/source/';
   plugin 'Fetch::CurlCommand';
 };

=head1 DESCRIPTION

This plugin provides a fetch based on the C<curl> command.  It works with other fetch
plugins (that is, the first one which succeeds will be used).  Most of the time the best plugin
to use will be L<Alien::Build::Plugin::Download::Negotiate>, but for some SSL bootstrapping
it may be desirable to try C<curl> first.

Protocols supported: C<http>, C<https>

C<https> support requires that curl was built with SSL support.

=head1 PROPERTIES

=head2 curl_command

The full path to the C<curl> command.  The default is usually correct.

=head2 ssl

Ignored by this plugin.  Provided for compatibility with some other fetch plugins.

=head1 METHODS

=head2 protocol_ok

 my $bool = $plugin->protocol_ok($protocol);
 my $bool = Alien::Build::Plugin::Fetch::CurlCommand->protocol_ok($protocol);
