These are the complete Japanese translations of the Gnus Info manuals,
corresponding to Gnus v5.13.

Installation
============
% ./configure
% make
% make install

You can specify Emacs which is used to format the Info files, and the
destination directory in which the Info files are installed:

% ./configure --with-emacs=EMACS --infodir=INFODIR

To know those default values, look into Makefile after running the
configure script without argument.  The value for EMACS doesn't allow
to have directory components like /usr/local/bin/emacs, so you have to
specify the PATH environment variable if it is needed.  For example:

% ./configure --with-emacs=emacs-30.0.50 --infodir=/usr/local/info

If you prefer to read those Japanese Info manuals when typing `C-cC-i'
in Gnus buffers or typing `M-x message-info' in message buffers, you
can add the following advice to the ~/.gnus.el file:

(advice-add
 'Info-goto-node :around
 ;; Prefer Japanese edition of Gnus Info manuals.
 (lambda (oldfun &rest args)
   (if (and (not (eq major-mode 'Info-mode))
	    (string-match "\\`(\\(emacs-mime\\|epa\\|gnus-coding\
\\|gnus-faq\\|gnus\\|gnus-news\\|message\\|sasl\\|sieve\\))"
			  (car args)))
       (condition-case nil
	   (apply oldfun
		  (cons
		   (concat (substring (car args) 0 (1- (match-end 0)))
			   "-ja"
			   (substring (car args) (1- (match-end 0))))
		   (cdr args)))
	 (error
	  (apply oldfun args)))
     (apply oldfun args)))
 '((name . prefer-japanese-edition)))
