=head1 NOTE

|

=head2 C<field-name>
|
| 903 |
|
| 904 |
The header field name is not case sensitive. To make the life
|
| 905 |
easier for perl users who wants to avoid quoting before the => operator,
|
| 906 |
you can use '_' as a synonym for '-' in header field names
|
| 907 |
(this behaviour can be suppressed by setting
|
| 908 |
C<translate_underscore> option to C<0> value).
