+;;; Change Log:
+
+;;  2 Apr 2007 - now using ChangeLog file
+;; 15 Mar 2007 - updated documentation
+;; 14 Mar 2007 - Changed how obsolete packages are handled
+;; 13 Mar 2007 - Wrote package-install-from-buffer
+;; 12 Mar 2007 - Wrote package-menu mode
+
+;;; Commentary:
+
+;; The idea behind package.el is to be able to download packages and
+;; install them.  Packages are versioned and have versioned
+;; dependencies.  Furthermore, this supports built-in packages which
+;; may or may not be newer than user-specified packages.  This makes
+;; it possible to upgrade Emacs and automatically disable packages
+;; which have moved from external to core.  (Note though that we don't
+;; currently register any of these, so this feature does not actually
+;; work.)
+
+;; This code supports a single package repository, ELPA.  All packages
+;; must be registered there.
+
+;; A package is described by its name and version.  The distribution
+;; format is either  a tar file or a single .el file.
+
+;; A tar file should be named "NAME-VERSION.tar".  The tar file must
+;; unpack into a directory named after the package and version:
+;; "NAME-VERSION".  It must contain a file named "PACKAGE-pkg.el"
+;; which consists of a call to define-package.  It may also contain a
+;; "dir" file and the info files it references.
+
+;; A .el file will be named "NAME-VERSION.el" in ELPA, but will be
+;; installed as simply "NAME.el" in a directory named "NAME-VERSION".
+
+;; The downloader will download all dependent packages.  It will also
+;; byte-compile the package's lisp at install time.
+
+;; At activation time we will set up the load-path and the info path,
+;; and we will load the package's autoloads.  If a package's
+;; dependencies are not available, we will not activate that package.
+
+;; Conceptually a package has multiple state transitions:
+;;
+;; * Download.  Fetching the package from ELPA.
+;; * Install.  Untar the package, or write the .el file, into
+;;   ~/.emacs.d/elpa/ directory.
+;; * Byte compile.  Currently this phase is done during install,
+;;   but we may change this.
+;; * Activate.  Evaluate the autoloads for the package to make it
+;;   available to the user.
+;; * Load.  Actually load the package and run some code from it.
+
+;; Other external functions you may want to use:
+;;
+;; M-x package-list-packages
+;;    Enters a mode similar to buffer-menu which lets you manage
+;;    packages.  You can choose packages for install (mark with "i",
+;;    then "x" to execute) or deletion (not implemented yet), and you
+;;    can see what packages are available.  This will automatically
+;;    fetch the latest list of packages from ELPA.
+;;
+;; M-x package-list-packages-no-fetch
+;;    Like package-list-packages, but does not automatically fetch the
+;;    new list of packages.
+;;
+;; M-x package-install-from-buffer
+;;    Install a package consisting of a single .el file that appears
+;;    in the current buffer.  This only works for packages which
+;;    define a Version header properly; package.el also supports the
+;;    extension headers Package-Version (in case Version is an RCS id
+;;    or similar), and Package-Requires (if the package requires other
+;;    packages).
+;;
+;; M-x package-install-file
+;;    Install a package from the indicated file.  The package can be
+;;    either a tar file or a .el file.  A tar file must contain an
+;;    appropriately-named "-pkg.el" file; a .el file must be properly
+;;    formatted as with package-install-from-buffer.

+;;; ToDo:
+
+;; - putting info dirs at the start of the info path means
+;;   users see a weird ordering of categories.  OTOH we want to
+;;   override later entries.  maybe emacs needs to enforce
+;;   the standard layout?
+;; - put bytecode in a separate directory tree
+;; - perhaps give users a way to recompile their bytecode
+;;   or do it automatically when emacs changes
+;; - give users a way to know whether a package is installed ok
+;; - give users a way to view a package's documentation when it
+;;   only appears in the .el
+;; - use/extend checkdoc so people can tell if their package will work
+;; - "installed" instead of a blank in the status column
+;; - tramp needs its files to be compiled in a certain order.
+;;   how to handle this?  fix tramp?
+;; - on emacs 21 we don't kill the -autoloads.el buffer.  what about 22?
+;; - maybe we need separate .elc directories for various emacs versions
+;;   and also emacs-vs-xemacs.  That way conditional compilation can
+;;   work.  But would this break anything?
+;; - should store the package's keywords in archive-contents, then
+;;   let the users filter the package-menu by keyword.  See
+;;   finder-by-keyword.  (We could also let people view the
+;;   Commentary, but it isn't clear how useful this is.)
+;; - William Xu suggests being able to open a package file without
+;;   installing it
+;; - Interface with desktop.el so that restarting after an install
+;;   works properly
+;; - Implement M-x package-upgrade, to upgrade any/all existing packages
+;; - Use hierarchical layout.  PKG/etc PKG/lisp PKG/info
+;;   ... except maybe lisp?
+;; - It may be nice to have a macro that expands to the package's
+;;   private data dir, aka ".../etc".  Or, maybe data-directory
+;;   needs to be a list (though this would be less nice)
+;;   a few packages want this, eg sokoban
+;; - package menu needs:
+;;     ability to know which packages are built-in & thus not deletable
+;;     it can sometimes print odd results, like 0.3 available but 0.4 active
+;;        why is that?
+;; - Allow multiple versions on the server...?
+;;   [ why bother? ]
+;; - Don't install a package which will invalidate dependencies overall
+;; - Allow something like (or (>= emacs 21.0) (>= xemacs 21.5))
+;;   [ currently thinking, why bother.. KISS ]
+;; - Allow optional package dependencies
+;;   then if we require 'bbdb', bbdb-specific lisp in lisp/bbdb
+;;   and just don't compile to add to load path ...?
+;; - Have a list of archive URLs?  [ maybe there's no point ]
+;; - David Kastrup pointed out on the xemacs list that for GPL it
+;;   is friendlier to ship the source tree.  We could "support" that
+;;   by just having a "src" subdir in the package.  This isn't ideal
+;;   but it probably is not worth trying to support random source
+;;   tree layouts, build schemes, etc.
+;; - Our treatment of the info path is somewhat bogus
+;; - perhaps have an "unstable" tree in ELPA as well as a stable one
