NAME
       CPANPLUS::Internals::Fetch - fetches files for CPANPLUS

SYNOPSIS
           my $output = $cb->_fetch(
                               module      => $modobj,
                               fetchdir    => '/path/to/save/to',
                               verbose     => BOOL,
                               force       => BOOL,
                           );

           $cb->_add_fail_host( host => 'foo.com' );
           $cb->_host_ok(       host => 'foo.com' );

DESCRIPTION
       CPANPLUS::Internals::Fetch fetches files from either ftp,
       http, file or rsync mirrors.

       This is the rough flow:

           $cb->_fetch
               Delegate to File::Fetch;

METHODS
$path = _fetch( module => $modobj, [fetchdir =>
       '/path/to/save/to', fetch_from =>
       'scheme://path/to/fetch/from', verbose => BOOL, force =>
       BOOL, prefer_bin => BOOL] )
       "_fetch" will fetch files based on the information in a
       module object. You always need a module object. If you
       want a fake module object for a one-off fetch, look at
       "CPANPLUS::Module::Fake".

       "fetchdir" is the place to save the file to. Usually this
       information comes from your configuration, but you can
       override it expressly if needed.

       "fetch_from" lets you specify an URI to get this file
       from. If you do not specify one, your list of configured
       hosts will be probed to download the file from.

       "force" forces a new download, even if the file already
       exists.

       "verbose" simply indicates whether or not to print extra
       messages.

       "prefer_bin" indicates whether you prefer the use of
       commandline programs over perl modules. Defaults to your
       corresponding config setting.

       "_fetch" figures out, based on the host list, what scheme
       to use and from there, delegates to "File::Fetch" do the
       actual fetching.

       Returns the path of the output file on success, false on
       failure.

       Note that you can set a "blacklist" on certain methods in
       the config.  Simply add the identifying name of the method
       (ie, "lwp") to:
           $conf->_set_fetch( blacklist => ['lwp'] );

       And the "LWP" function will be skipped by "File::Fetch".

       _add_fail_host( host => $host_hashref )

       Mark a particular host as bad. This makes
       "CPANPLUS::Internals::Fetch" skip it in fetches until this
       cache is flushed.

       _host_ok( host => $host_hashref )

       Query the cache to see if this host is ok, or if it has
       been flagged as bad.

       Returns true if the host is ok, false otherwise.
