CPAN::Uploader - upload things to the CPAN

=head1 VERSION

version 0.103013

=head1 METHODS

=head2 upload_file

  CPAN::Uploader->upload_file($file, \%arg);

  $uploader->upload_file($file);

Valid arguments are:

  user       - (required) your CPAN / PAUSE id
  password   - (required) your CPAN / PAUSE password
  subdir     - the directory (under your home directory) to upload to
  http_proxy - uri of the http proxy to use
  upload_uri - uri of the upload handler; usually the default (PAUSE) is right
  debug      - if set to true, spew lots more debugging output

This method attempts to actually upload the named file to the CPAN.  It will
raise an exception on error.

=head2 new

  my $uploader = CPAN::Uploader->new(\%arg);

This method returns a new uploader.  You probably don't need to worry about
this method.

Valid arguments are the same as those to C<upload_file>.

=head2 read_config_file

  my $config = CPAN::Uploader->read_config_file( $filename );

This reads the config file and returns a hashref of its contents that can be
used as configuration for CPAN::Uploader.

If no filename is given, it looks for F<.pause> in the user's home directory
(from the env var C<HOME>, or the current directory if C<HOME> isn't set).

See L<cpan-upload/CONFIGURATION> for the config format.

=head2 log

  $uploader->log($message);

This method logs the given string.  The default behavior is to print it to the
screen.  The message should not end in a newline, as one will be added as
needed.

=head2 log_debug

This method behaves like C<L</log>>, but only logs the message if the
CPAN::Uploader is in debug mode.
