address@hidden package archive
+
+ Via the Package Menu, users may download packages from @dfn{package
+archives}. Such archives are specified by the variable
address@hidden, whose default value contains a single entry:
+the archive hosted by the GNU project at @url{elpa.gnu.org}. This
+section describes how to set up and maintain a package archive.
+
address@hidden base location, package archive
address@hidden package-archives
+The value of this variable is an alist of package archives recognized
+by the Emacs package manager.
+
+Each alist element corresponds to one archive, and should have the
+form @code{(@var{id} . @var{location})}, where @var{id} is the name of
+the archive (a string) and @var{location} is its @dfn{base location}
+(a string).
+
+If the base location starts with @samp{http:}, it is treated as a HTTP
+URL, and packages are downloaded from this archive via HTTP (as is the
+case for the default GNU archive).
+
+Otherwise, the base location should be a directory name. In this
+case, Emacs retrieves packages from this archive via ordinary file
+access. Such ``local'' archives are mainly useful for testing.
address@hidden defopt
+
+ A package archive is simply a directory in which the package files,
+and associated files, are stored. If you want the archive to be
+reachable via HTTP, this directory must be accessible to a web server.
+How to accomplish this is beyond the scope of this manual.
+
+ A convenient way to set up and update a package archive is via the
address@hidden library. This is included with Emacs, but not loaded
+by default; type @kbd{M-x load-library @kbd{RET} package-x @kbd{RET}}
+to load it, or add @code{(require 'package-x)} to your init file.
address@hidden Libraries,, Lisp Libraries, emacs, The GNU Emacs Manual}.
+Once loaded, you can make use of the following:
+
address@hidden package-archive-upload-base
+The value of this variable is the base location of a package archive,
+as a directory name. The commands in the @code{package-x} library
+will use this base location.
+
+The directory name should be absolute. You may specify a remote name,
+such as @file{/ssh:foo@@example.com:/var/www/packages/}, if the
+package archive is on a different machine. @xref{Remote Files,,
+Remote Files, emacs, The GNU Emacs Manual}.
address@hidden defopt
+
address@hidden Command package-upload-file filename
+This command prompts for @var{filename}, a file name, and uploads that
+file to @code{package-archive-upload-base}. The file must be either a
+simple package (a @file{.el} file) or a multi-file package (a
address@hidden file); otherwise, an error is raised. The package
+attributes are automatically extracted, and the archive's contents
+list is updated with this information.
+
+If @code{package-archive-upload-base} does not specify a valid
+directory, the function prompts interactively for one. If the
+directory does not exist, it is created. The directory need not have
+any initial contents (i.e., you can use this command to populate an
+initially empty archive).
address@hidden deffn
+
address@hidden Command package-upload-buffer
+This command is similar to @code{package-upload-file}, but instead of
+prompting for a package file, it uploads the contents of the current
+buffer. The current buffer must be visiting a simple package (a
address@hidden file) or a multi-file package (a @file{.tar} file);
+otherwise, an error is raised.
address@hidden deffn
+
address@hidden
+After you create an archive, remember that it is not accessible in the
+Package Menu interface unless it is in @code{package-archives}.
