+"""Functions used to send email messages.
+
+The following are the possible fields of an email message:
+
+  sender: The email address of the sender, the From address. This must be the 
+    email address of a registered administrator for the application, or the
+    address of the current signed-in user. Administrators can be added to
+    an application using the Administration Console. The current user's email
+    address can be determined with the Users API.
+  to: A recipient's email address (a string) or a list of email addresses to 
+    appear on the To: line in the message header.
+  cc: A recipient's email address (a string) or a list of email addresses to 
+    appear on the Cc: line in the message header.
+  bcc: A recipient's email address (a string) or a list of email addresses to 
+    receive the message, but not appear in the message header ("blind carbon 
+    copy").
+  reply_to: An email address to which a recipient should reply instead of the 
+    sender address, the Reply-To: field.
+  subject: The subject of the message, the Subject: line.
+  body: The plaintext body content of the message.
+  html: An HTML version of the body content, for recipients that 
+    prefer HTML email.
+  attachments: The file attachments for the message, as a list of two-value 
+    tuples, one tuple for each attachment. Each tuple contains a filename as 
+    the first element, and the file contents as the second element.
+    An attachment file must be one of the allowed file types, and the 
+    filename must end with an extension that corresponds with the type. 
+    For a list of allowed types and filename extensions, see Allowed 
+    Attachment Types.
+
+Usage:
+
+  context = { 'sender': 'melange-noreply@foo.com',
+              'to': 'bob@bar.com',
+              'subject': 'You have been invited to become a Host',
+              'sender_name': 'Alice',
+              'to_name': 'Melange Team',
+              'role': 'Host',
+              'group': 'Google Summer of Code 2009',
+              'invitation_url': 'http://invitation-url'}
