-;;; Commentary:
-
-;; A package management library for Emacs, based on package.el.
-
-;; The purpose of this library is to wrap all the quirks and hassle of
-;; package.el into a sane API.
-
-;; The following functions comprise the public interface of this library:
-
-;;; Package directory selection
-
-;; `epl-package-dir' gets the directory of packages.
-
-;; `epl-default-package-dir' gets the default package directory.
-
-;; `epl-change-package-dir' changes the directory of packages.
-
-;;; Package system management
-
-;; `epl-initialize' initializes the package system and activates all
-;; packages.
-
-;; `epl-reset' resets the package system.
-
-;; `epl-refresh' refreshes all package archives.
-
-;; `epl-add-archive' adds a new package archive.
-
-;;; Package objects
-
-;; Struct `epl-requirement' describes a requirement of a package with `name' and
-;; `version' slots.
-
-;; `epl-requirement-version-string' gets a requirement version as string.
-
-;; Struct `epl-package' describes an installed or installable package with a
-;; `name' and some internal `description'.
-
-;; `epl-package-version' gets the version of a package.
-
-;; `epl-package-version-string' gets the version of a package as string.
-
-;; `epl-package-summary' gets the summary of a package.
-
-;; `epl-package-requirements' gets the requirements of a package.
-
-;; `epl-package-directory' gets the installation directory of a package.
-
-;; `epl-package-from-buffer' creates a package object for the package contained
-;; in the current buffer.
-
-;; `epl-package-from-file' creates a package object for a package file, either
-;; plain lisp or tarball.
-
-;; `epl-package-from-descriptor-file' creates a package object for a package
-;; description (i.e. *-pkg.el) file.
-
-;;; Package database access
-
-;; `epl-package-installed-p' determines whether a package is installed, either
-;; built-in or explicitly installed.
-
-;; `epl-package-outdated-p' determines whether a package is outdated, that is,
-;; whether a package with a higher version number is available.
-
-;; `epl-built-in-packages', `epl-installed-packages', `epl-outdated-packages'
-;; and `epl-available-packages' get all packages built-in, installed, outdated,
-;; or available for installation respectively.
-
-;; `epl-find-built-in-package', `epl-find-installed-packages' and
-;; `epl-find-available-packages' find built-in, installed and available packages
-;; by name.
-
-;; `epl-find-upgrades' finds all upgradable packages.
-
-;; `epl-built-in-p' return true if package is built-in to Emacs.
-
-;;; Package operations
-
-;; `epl-install-file' installs a package file.
-
-;; `epl-package-install' installs a package.
-
-;; `epl-package-delete' deletes a package.
-
-;; `epl-upgrade' upgrades packages.
