+
+;;; Commentary:
+
+;; Crawl Erlang/OTP HTML documentation and generate lookup tables.
+;;
+;; This package depends on `cl-lib', `pcase' and
+;; `libxml-parse-html-region'; emacs 24+ compiled with libxml2 should
+;; work. On emacs 24.1 and 24.2 do `M-x package-install RET cl-lib
+;; RET' to install `cl-lib'.
+;;
+;; Please customise `erldoc-man-index' to point to your local OTP
+;; documentation.
+;;
+;; To use:
+;;
+;; (define-key help-map "u" 'erldoc-browse)
+;; (define-key help-map "t" 'erldoc-browse-topic)
+;; (define-key help-map "a" 'erldoc-apropos)
+;;
+;; Note: these commands trigger indexing OTP documentation on first
+;; run with cache to disk which may take 1-2 minutes.
+
+
+;;; Examples:
+
+;; 1. `M-x erldoc-browse RET erlang:integer_to_binary/2 RET' opens the
+;; `erlang' manual anchored on the entry for `integer_to_binary/2'.
+;;
+;; 2. `M-x erldoc-apropos RET first RET' list all MFAs matching
+;; substring `first'.
+;;
+;; 3. `M-x erldoc-browse-topic RET efficiency_guide#Introduction RET'
+;; opens chapter `Introduction' of the `Efficiency Guide' in the
+;; browser.
+
+;;; History:
+
+;; Written in December 2013 as a temporary solution to help me browse
+;; the rich Erlang/OTP documentation. Three years on I find myself
+;; still using it every day. - Leo (2016)
