* *iso-2022-jp*

Since Mew supports Mule(MULtilingual Enhancement to GNU Emacs),
byte-compile-file on pure Emacs shows following warnings.

	While compiling toplevel forms in file mew.el:
	  !! Symbol's value as variable is void ((*iso-2022-jp*))

Please don't care. It's not harmful since Mew never uses *iso-2022-jp*
symbol in pure Emacs. *iso-2022-jp* means a standard charter set for
Japanese.


* ISO-8859-1

Both US-ASCII and ISO-8859-1 are supported on Emacs 19.

If you use character codes other than US-ASCII and ISO-8859-1, please
use Mule. Mule is available by anonymous ftp from:

        etlport.etl.go.jp [192.31.197.99]:/pub/mule
        ftp.mei.co.jp [132.182.49.2]:/public/free/gnu/emacs/Mule
        sh.wide.ad.jp [133.4.11.11]:/JAPAN/mule/mule-1.0
        ftp.funet.fi [128.214.6.100]:/pub/gnu/emacs/mule
        cs.huji.ac.il [132.65.16.10]:/pub/gnu/mule


* PGP(Pretty Good Privacy)

Mew is tested with PGP 2.6ui(unofficial international version) and
2.6.i. But I hopefully guess Mew works with any other versions higher
than 2.3a.

PGP 2.6ui is available as follows;

    ftp://ftp.demon.co.uk/pub/pgp/pgp26ui-src.tar.gz
    ftp://ftp.aist-nara.ac.jp/pub/Security/tool/pgp/pgp26ui-src.tar.gz

PGP 2.6.i is available as follows;

    ftp://ftp.dsi.unimi.it/pub/security/crypt/PGP/pgp26is.tar.gz
    ftp://ftp.aist-nara.ac.jp/pub/Security/tool/pgp/pgp26is.tar.gz

PGP 2.6.2i is available as follows; 

    ftp://ftp.aist-nara.ac.jp/pub/Security/tool/pgp/pgp262is.tar.gz

Mew uses 'Content-Type: application/pgp' for its tag to integrate PGP
and MIME. For more information, see 00pgp-mime.

Some people use application/x-pgp as a tag. But Mew will never support it.
If PGP message is not automatically decrypted or verified (or both)
due to the lack of 'Content-Type: application/pgp', type C-cd in summary
mode to force decrypting or verifying (or both).



* PEM(Privacy Enhanced Mail)

Mew supports only FJPEM. It's available from the following site.

    ftp://sh.wide.ad.jp/WIDE/free-ware/fjpem/fjpem1.2.tar.gz
    ftp://ftp.wg.omron.co.jp/pub/security/tools/fjpem1.2.tar.gz
    ftp://ftp.aist-nara..ac.jp/pub/Security/tool/pem/fjpem1.2.tar.gz
    ftp://ftp.u-tokyo.ac.jp/pub/Mail/security/fjpem1.2.tar.gz
    ftp://ftp.iij.ad.jp/pub/security/WIDE/fjpem1.2.tar.gz
    ftp://ftp.dit.co.jp/pub/security/WIDE/fjpem1.2.tar.gz
    ftp://ftp.kuis.kyoto-u.ac.jp/net/security/fjpem1.2.tar.gz
    ftp://ftp.fujixerox.co.jp/pub/Unix/Security/fjpem1.2.tar.gz
    ftp://ftp.fujitsu.co.jp/pub/security/fjpem/fjpem1.2.tar.gz


I don't believe this PEM is useful for people other than Japanese
due to its Japanese documents and keyserv issue.

Please pay attention that Mew uses 'Content-Type:
Application/Pem-1421' as a tag. It is just to support conventional PEM
because there is no way to tell whether this message is a PEM or not
without a tag. It's just a temporary solution for backward
compatibility.

Since Mew supports only conventional PEM, what you can do is just
sign or encrypt a plain text. You can't make a MIME message PEM or
include PEM to MIME multipart. 


* To read application/pem-1421 with other applications.

mhn:

Add the following line to .mh_profile

	mhn-show-application/pem-1421: %l/usr/local/bin/pemcrypt -d -i < '%F' | $PAGER

Metamail:

Add the following line to ~/.mailcap.

	application/pem-1421; /usr/local/bin/pemcrypt -d -i < %s ; 


* Adjusting a multipart message after C-cC-m.

If you want to adjust a message after typing C-cC-m on draft mode,
please take care to modify appropriately. (You'd better learn MIME
syntax.) If the message is multipart, never insert string before the
first boundary and after the last boundary. The preamble and epilogue
is ignored by mail interface.


* xv

"xv" is a share ware to display gif, jpeg, bitmap and so on. If you
don't like to pay for it, alternative free software is "xloadimage" or
"display". I may change the default software to "display" to get rid
of the dependency of share ware.


* X-Face:

To display X-Face:, you need to set following the three variables.

(defvar mew-x-face-filter '("uncompface" "ikon2xbm"))
(defvar mew-x-face-prog "xv")
(defvar mew-x-face-args nil)

"uncompface" and ikon2xbm are included in the "faces" package. It is
available from;

ftp://moose.cs.indiana.edu/pub/faces/faces/faces-1.6.1.tar.Z
ftp://ftp.ics.es.osaka-u.ac.jp/unix/misc/faces-1.6.1.tar.Z

Type "C-cC-x" to display X-Face: in summary mode.
