Don't call pkg_info to get the installed Emacs version; always use the
version matching EMACS_TYPE set by users. Be DEPENDS to it. This should
address pkg/37146 by Aleksey Cheusov.
While here convert some emacs lisp packages to user-destdir.
* misc/ruby-mode.el: move fontifying code from hook. a patch from
Phil Hagelberg <phil at hagelb.org> in [ruby-core:16636].
* misc/rdebug.el, misc/README: Remove rdebug.el as per request
from the maintainer and mention the ruby-debug project at
RubyForge in README; bug#19043.
* misc/ruby-style.el (ruby-style-{case,label}-indent): fix for labels
inside blocks in switch and function top level.
* misc/ruby-mode.el (ruby-mode): should use `run-mode-hooks' instead
of calling `run-hooks' directly to run the mode hook. patch from
Chiyuan Zhang <pluskid AT gmail.com> in [ruby-core:15915]
* misc/ruby-mode.el (ruby-parse-partial): handle stringified
symbols properly using ruby-forward-string.
* misc/ruby-style.el (ruby-style-label-indent): for yacc rules.
* misc/ruby-style.el: new file. C/C++ style for ruby source code.
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.
