;;; Commentary:
;; phobos.el provides several functions for viewing Phobos documentation
;; and documentation for other D libraries. These functions open the
;; documentation in a web browser, calling the process `phobos-browser'.
;; These functions are provided:
;; * `phobos': view Phobos documentation
;; * `dub-doc': view documentation for a symbol in a dub package
;; * `describe-dub-package': view the home page for a dub package
;; An alias `view-dub-documentation' also exists for `dub-doc'.
