1) Simplify the way how an emacs version is picked when no emacs
is installed, but a user try to install an Emacs Lisp package.
Just pick up the version set as EMACS_TYPE than searching for
versions already installed etc. If the EMACS_TYPE version is
not supported by the Emacs Lisp Package, just fail. EMACS_TYPE
be default to GNU Emacs 21.
(In other words, users should set EMACS_TYPE as they want.
Otherwise GNU Emacs 21 is used.)
2) All Emacs Lisp Packages *must* prepend EMACS_PKGNAME_PREFIX to
a) the PKGNAME itself, and b) PKGNAME in its dependency lines.
EMACS_PKGNAME_PREFIX is expanded to "xemacs-" when XEmacs is
used. This keeps dependency graph of Emacs-Lisp-packages-
installed-for-XEmacs consistent.
3) Document EMACS_* variables as much as possible.
4) Provide more cookies for PLIST. Maybe utilized later.
Note that the 2) change doesn't affect the default, GNU Emacs 21
behaviour. So no version / revision bumps in this commit.
User visible change summary:
* w3m.el (w3m-goto-url): Display a help message to stop
asynchronous process.
* w3m.el (w3m-emacs-w3m-icon): Use helvetica-bold to widen image.
* w3m.el (w3m-lynx-like-map): Don't define key bindings for
`w3m-zoom-out-image' and `w3m-zoom-in-image' when emacs-w3m in
running in non-graphical display.
* w3m.el (w3m-w3m-dump-head-source): Display the message which
describes how to stop asynchronous process.
(w3m-lynx-like-map): Changed the key binded to `w3m-process-stop'
from `C-c C-g' to `C-c C-k'.
* w3m-image (w3m-resize-image-by-rate): Limit the minimum scale.
* w3m.el (w3m-resize-inline-image-internal): Remove an existing
image only for XEmacs.
* w3m.el (w3m-resize-inline-image-internal): Remove an existing
image before resizing.
* w3m.el (w3m-lynx-like-map): Unbind the key "N" to the command
`w3m-namazu' in order to avoid binding collision to
`w3m-view-next-page'. Thanks to Satoshi TAOKA for his report.
* w3m.el (w3m-lynx-like-map): Bind key M-] to `w3m-zoom-in-image';
bind key M-[ to `w3m-zoom-out-image'.
Emacs-w3m, a simple interface program of w3m, which works on Emacs.
w3m itself is a good program for WWW. Emacs-w3m provides an interface of w3m
on Emacs so that users can use Emacs's editing environment for WWW access.
This benefits multibyte language users.
