ERRORS
     new():
             400 Malformed multipart, no terminating boundary.
             400 No boundary supplied for multipart/form-data.
             405 Not Allowed - File uploads are disabled.
             413 Request entity too large: %s bytes on STDIN exceeds post_max !
             500 Bad read! wanted %s, got %s.
             500 IO::File can\'t create new temp_file.
             500 IO::File is not available %s.
             Bad parameter separator '%s'.
             From Class::Utils::set_params():
                     Unknown parameter '%s'.

     append_param():
             Parameter '%s' has bad value.

     upload():
             Cannot close file '%s': %s.
             Cannot write file '%s': %s.
             File uploads only work if you specify enctype="multipart/form-data" in your form.
             No filehandle for '%s'. Are uploads enabled (disable_upload = 0)? Is post_max big enough?
             No filename submitted for upload to '$writefile'.

     upload_info():
             File uploads only work if you specify enctype="multipart/form-data" in your form.

EXAMPLE1
     use strict;
     use warnings;

     use CGI::Pure;

     # Object.

     foreach my $param_key ($cgi->param) {
             print "Param '$param_key': ".join(' ', $cgi->param($param_key))."\n";
