      <para>This class represents a single part of a <acronym>MIME</acronym> message. It contains the
      actual content of the message part plus information about its encoding,
      content type and original filename. It provides a method for generating a
      string from the stored data. <classname>Zend_Mime_Part</classname> objects can be
      added to <link
      linkend="zend.mime.message"><classname>Zend_Mime_Message</classname></link> to
      assemble a complete multipart message.</para>

    <title>Instantiation</title>

    <para><classname>Zend_Mime_Part</classname> is instantiated with a string that
    represents the content of the new part. The type is assumed to be
    OCTET-STREAM, encoding is 8Bit. After instantiating a
    <classname>Zend_Mime_Part</classname>, meta information can be set by accessing its
    attributes directly:</para>

    <programlisting language="php"><![CDATA[
public $type = Zend_Mime::TYPE_OCTETSTREAM;
public $encoding = Zend_Mime::ENCODING_8BIT;
public $id;
public $disposition;
public $filename;
public $description;
public $charset;
public $boundary;
public $location;
public $language;

  <sect2 id="zend.mime.part.methods">
    <title>Methods for rendering the message part to a string</title>

    <para><methodname>getContent()</methodname> returns the encoded content of the
    MimePart as a string using the encoding specified in the attribute
    $encoding. Valid values are Zend_Mime::ENCODING_* Characterset conversions are
    not performed.</para>

    <para>
        <methodname>getHeaders()</methodname> returns the Mime-Headers for the
        MimePart as generated from the information in the publicly accessible
        attributes. The attributes of the object need to be set correctly before
        this method is called.
