161 Constructs a new C<Message::Headers> object. You might pass some initial

168 Content_Type => 'text/html',

179 Parses given C<header> and constructs a new C<Message::Headers>
180 object. You might pass some additional C<field-name>-C<field-body> pairs
181 or/and initial options as parameters to the constructor.

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