+1/ Introduction
+---------------
+
+libEtPan! is mainly a library that will handle all kind of mailbox access.
+For example: IMAPrev4, POP3, NNTP, mbox, MH.
+
+You have two kinds of mailbox access, either using low-level functions
+with a different interface for each kind of access or using higher-level
+functions, using a driver to wrap the higher-level API.
+
+
+2/ Low-level

+
+3/ Higher-level
+---------------
+
+The higher level will allow us to query folder informations or to get
+messages information or content.
+
+There is four kinds of identities :
+- storage
+- folders
+- session
+- messages
+
+In the higher-level interface, you manipulate data types from IMF and
+MIME module, plus additionnal data types of higher-level.
+
+
+3.1/ Objects
+------------
+
+3.1.1/ Storage
+
+A storage (struct mail_storage) represents whether a server or
+a main path, It can be an IMAP server, the root path of a MH or a mbox file.
+
+
+3.1.2/ Folders
+
+A folder can be created from a storage.
+Folders (struct mail_folder) are the mailboxes we can choose in the
+server or as sub-folder of the main path.
+
+Folders for IMAP are the IMAP mailboxes, for MH this is one of the
+folder of the MH storage, for mbox, there is only one folder, the
+mbox file content;
+
+
+3.1.3/ Session
+
+Storage and folders communicate with the lower-layer through the
+mail session data structure.
+
+A mail session (struct mailsession) is a mail access to a server
+or a mail access in the local file system. It allow us to send commands
+to the mail access.
+
+A mail storage is using a mail session to communicate.
+A folder folder also uses a mail session to get information or to send
+information. It can be the same session or not, depdending of the
+implementation.
+
+
+3.1.4/ Messages
+
+From a session, we can get a message (struct mailmessage) to read.
+
+
+3.2/ Drivers
+------------
+
+For a mail access, three drivers exist.
+One for storage, one for session, one for message.
+Note that the folder access rely only on session driver.
+
+
+3.2.1/ storage driver interface
+
+  mail_storage_driver is the driver structure for mail storage
+
+  - name is the name of the driver
+  
+  - connect() connects the storage to the remote access or to
+      the path in the local filesystem.
+      
+  - get_folder() can have two kinds of behaviour.
+      Either it creates a new session and independant from the session
+      used by the storage and select the given mailbox or
+      it selects the given mailbox in the current session.
+      It depends on the efficiency of the mail driver.
+
+  - free_data() frees the data created with mail_storage constructor.
+
+  a constructor for each kind of access has to be implemented.
+  
+
+3.2.2/ session driver interface
+
+  maildriver is the driver structure for mail sessions
+
+  - name is the name of the driver
+  
+  - initialize() is the function that will initializes a data structure
+      specific to the driver, it returns a value that will be stored
+      in the field data of the session.
+      The field data of the session is the state of the session,
+      the internal data structure used by the driver.
+      It is called when creating the mailsession structure with
+      mailsession_new().
+  
+  - uninitialize() frees the structure created with initialize()
+
+  - parameters() implements functions specific to the given mail access
+  
+  - connect_stream() connects a stream to the session
+
+  - connect_path() notify a main path to the session
+
+  - starttls() changes the current stream to a TLS stream
+  
+  - login() notifies the user and the password to authenticate to the
+      session
+
+  - logout() exits the session and closes the stream
+
+  - noop() does no operation on the session, but it can be
+      used to poll for the status of the connection.
+
+  - check_folder() makes a checkpoint of the session
+
+  - select_folder() selects a mailbox
+
+  - expunge_folder() deletes all messages marked \Deleted
+
+  - status_folder() queries the status of the folder
+      (number of messages, number of recent messages, number of
+      unseen messages)
+
+  - append_message() adds a RFC 2822 message to the current
+      given mailbox
+
+  - get_messages_list() returns the list of message numbers
+      of the current mailbox.
+
+  - get_envelopes_list() fills the parsed fields in the
+      mailmessage structures of the mail_envelopes_list.
+
+  - remove_message() removes the given message from the mailbox.
+      The message is permanently deleted.
+
+  - get_message returns a mailmessage structure that corresponds
+      to the given message number.
+
+
+3.2.3/ message driver interface
+
+  mailmessage_driver is the driver structure to get information from messages.
+  
+  - name is the name of the driver
+
+  - initialize() is the function that will initializes a data structure
+      specific to the driver, it returns a value that will be stored
+      in the field data of the mailsession.
+      The field data of the session is the state of the session,
+      the internal data structure used by the driver.
+      It is called when initializing the mailmessage structure with
+      mailmessage_init().
+  
+  - uninitialize() frees the structure created with initialize().
+      It will be called by mailmessage_free().
+
+  - flush() will free from memory all temporary structures of the message
+      (for example, the MIME structure of the message).
+
+  - fetch_result_free() will free all strings resulted by fetch() or
+      any fetch_xxx() functions that returns a string.
+
+  - fetch() returns the content of the message (headers and text).
+
+  - fetch_header() returns the content of the headers.
+
+  - fetch_body() returns the message text (message content without headers)
+
+  - fetch_size() returns the size of the message content.
+
+  - get_bodystructure() returns the MIME structure of the message.
+
+  - fetch_section() returns the content of a given MIME part
+
+  - fetch_section_header() returns the header of the message
+      contained by the given MIME part.
+
+  - fetch_section_mime() returns the MIME headers of the
+      given MIME part.
+
+  - fetch_section_body() returns the text (if this is a message, this is the
+      message content without headers) of the given MIME part.
+
+  - fetch_envelope() returns a mailimf_fields structure, with a list of
+      fields chosen by the driver.
+
+  - get_flags() returns a the flags related to the message.
+      When you want to get flags of a message, you have to make sure to
+      call get_flags() at least once before using directly message->flags.

+3.3.2/ Interfaces
+
+Include for this module is libetpan.h and includes all other headers.
+
+
+The interface of higher layer is documented in the following files :
+
+maildriver.h
+maildriver_types.h
+maildriver_types_helper.h
+mailmessage.h
+mailstorage.h
+mailstorage_types.[h]

+
+4/ Architecture
+---------------
+
+(see layer.fig)
+
+
+5/ Example of use
+-----------------
+
+You can find some example in tests/
+
+
+6/ Constraints
+--------------
+
+- libEtPan! must run on a system where mmap() is available.
+
+- for mbox particularly, libEtPan! make assumption on the fact that a
+    file can be entirely mapped into memory. But if you don't read
+        mailboxes of 1 Go, it should be fine.

+        The purpose of this mail library is to provide a portable,
+        efficient middleware for different kinds of mail access
+        (IMAPrev4, POP3, NNTP, mbox, MH, Maildir).
+      </para>
+      
+      <para>
+        You have two kinds of mailbox access, either using low-level
+        functions with a different interface for each kind of access
+        or using higher-level functions, using a driver to wrap the
+        higher-level API. The API will be the same for each kind of
+        mail access using the higher-level API.

+compose-msg
+-----------
+
+creates a RFC 2822 message with MIME parts
+
+syntax: compose-msg "text" filename
+
+
+
+all the following programs will take as argument :
+
+  --driver=(pop3|imap|nntp|mbox|mh)  -d pop3 (pop3|imap|nntp|mbox|mh)
+
+  default driver is mbox
+
+  --server={server-name} -s {server-name}
+  --port={port-number}   -p {port-number}
+  --tls                  -t
+  --starttls             -x
+  --user={login}         -u {login}
+  --password={password}  -v {password}
+  --path={mailbox}       -l {mailbox}
+  --apop                 -a
+  --cache={directory}    -c {directory}
+
+the default driver is mbox with the path /var/mail/$USER
+
+frm-simple, frm, frm-tree
+-------------------------
+
+frm-simple will list all the mails of a mailbox without any MIME decoding.
+
+frm will list all the mails of a mailbox and will decode the fields.
+
+frm-tree will do the same thing as frm and will also show the threads
+  of the folder.
+
+
+fetch-attachment
+----------------
+
+  fetch-attachment gets all the named attachment of the given message
+of the chosen mailbox and writes them on the current directory.
+
+  The program should be given message numbers (as given by frm) as
+additionnal arguments.
+
+
+readmsg-simple, readmsg
+-----------------------
+
+  readmsg-simple will display the content of the given messages.
+All the content (headers and body) will be displayed.
+
+  readmsg will display only the text parts of the given messages.
+
+  The program should be given message numbers (as given by frm) as
+additionnal arguments.
