What's SEMI?
============

  SEMI is a library to provide MIME feature for GNU Emacs.  MIME is a
  proposed internet standard for including content and headers other
  than (ASCII) plain text in messages.

	RFC 2045 : Internet Message Bodies
	RFC 2046 : Media Types
	RFC 2047 : Message Header Extensions
	RFC 2048 : MIME Registration Procedures
	RFC 2049 : MIME Conformance

  SEMI has the following features:

	- MIME message viewer   (mime-view-mode) (RFC 2045 .. 2049)
	- MIME message composer (mime-edit-mode) (RFC 2045 .. 2049)

  MIME message viewer and composer also support following features:

	- filename handling by Content-Disposition field (RFC 1806)
	- PGP/MIME security Multiparts (RFC 2015)
	- application/pgp (draft-kazu-pgp-mime-00.txt; obsolete)
	- text/richtext (RFC 1521; obsolete; preview only)
	- text/enriched (RFC 1896)
	- External method configuration by mailcap (RFC 1524)

  Notice that this package does not contain MIME extender for any
  MUAs.  They are released as separated packages.


Required environment
====================

  SEMI supports XEmacs 21.1 or later, and GNU Emacs 20.4 or later.

  SEMI does not support anything older than GNU Emacs 19.28 or XEmacs
  19.14.  In addition, SEMI does not word with byte-indexing Mule
  implementations, such as Mule 1, Mule 2 and GNU Emacs 20.1/20.2.

  SEMI also does not support Emacs 19.29 to 19.34, XEmacs 19.15 or
  XEmacs 20.2, but SEMI may work with them.

  SEMI requires APEL (10.7 or later) and FLIM (1.14.2 or later)
  package.  Please install them before installing it.  APEL package is
  available at:

	http://git.chise.org/elisp/dist/apel/

  and FLIM package is available at:

	http://git.chise.org/elisp/dist/flim/flim-1.14/


Installation
============

(a) run in expanded place

  If you don't want to install other directories, please do only
  following:

	% make

  You can specify the emacs command name, for example

	% make EMACS=xemacs

  If `EMACS=...' is omitted, EMACS=emacs is used.

(b) make install

  If you want to install other directories, please do following:

	% make install

  You can specify the emacs command name, for example

	% make install EMACS=xemacs

  If `EMACS=...' is omitted, EMACS=emacs is used.

  You can specify the prefix of the directory tree for Emacs Lisp
  programs and shell scripts, for example:

	% make install PREFIX=~/

  If `PREFIX=...' is omitted, the prefix of the directory tree of the
  specified emacs command is used (perhaps /usr/local).

  For example, if PREFIX=/usr/local and EMACS 19.34 is specified, it
  will create the following directory tree:

	/usr/local/share/emacs/19.34/site-lisp/  --- emu
	/usr/local/share/emacs/site-lisp/apel/   --- APEL
	/usr/local/share/emacs/site-lisp/flim/   --- FLIM
	/usr/local/share/emacs/site-lisp/semi/   --- SEMI

  You can specify site-lisp directory, for example

	% make install LISPDIR=~/share/emacs/lisp

  If `LISPDIR=...' is omitted, site-lisp directory of the specified
  emacs command is used (perhaps /usr/local/share/emacs/site-lisp or
  /usr/local/lib/xemacs/site-lisp).

  If the emu modules (included in APEL package) have been installed in
  the non-standard directory, you should specify where they will be
  found, for example:

	% make install VERSION_SPECIFIC_LISPDIR=~/elisp

(c) install as a XEmacs package

  If you want to install to XEmacs package directory, please do
  following:

	% make install-package

  You can specify the emacs command name, for example

	% make install-package XEMACS=xemacs-21

  If `XEMACS=...' is omitted, XEMACS=xemacs is used.

  You can specify the package directory, for example:

	% make install PACKAGEDIR=~/.xemacs

  If `PACKAGEDIR=...' is omitted, the first existing package
  directory is used.

  Notice that XEmacs package system requires XEmacs 21.0 or later.

(a,b,c)

  You can specify other optional settings by editing the file
  ${archive}/SEMI-CFG.  Please read ${archive}/README.en and comments
  in ${archive}/SEMI-CFG.


Initialization
==============

(a) load-path

  If you are using Emacs or Mule, please add directory of emu, apel,
  flim and semi to load-path.  If you install by default setting, you
  can write subdirs.el for example:

  --------------------------------------------------------------------
  (normal-top-level-add-to-load-path
   '("apel" "flim" "semi"))
  --------------------------------------------------------------------

  If you are using XEmacs, there are no need of setting about
  load-path.

(b) mime-setup

  Please insert the following into your ~/.emacs:

	(load "mime-setup")

Git based development
=====================

  The SEMI development sources can be accessed via Git repository.
  You can get the latest SEMI sources by the following:
  
  % git clone http://git.chise.org/git/elisp/semi.git

  Or you can view the SEMI repository via WWW at:

    http://git.chise.org/gitweb/?p=elisp/semi.git

  If you would like to join Git based development, please declare it
  in the Emacs-MIME mailing list at first.

  We hope you will join the open development.
