|
|
|
|
my $cgi = new Bugzilla::CGI();
|
|
|
|
=head1 DESCRIPTION
|
|
|
|
This package inherits from the standard CGI module, to provide additional
|
|
Bugzilla-specific functionality. In general, see L<the CGI.pm docs|CGI> for
|
|
documention.
|

|
|
=item C<cgi_error> is automatically checked
|
|
|
|
After creating the CGI object, C<Bugzilla::CGI> automatically checks
|
|
I<cgi_error>, and throws a CodeError if a problem is detected.

|
|
|

|
|
Values in C<@exclude> are not included in the result.
