-;; Provides a Regex IDE, invoked by `=regex'. If opened with C-u, opens in a
-;; separate frame with a dummy text buffer.
+;; Often, I find myself writing regular expressions that could terrify seasoned
+;; programmers (or little children). To hone my regex fu, I need a regex
+;; playground. Sure, there's regexr.com, but don't be silly, that's not Emacs.
+;;
+;; Sadly, the Emacs' regex syntax is niche and lacks support for a few
+;; questionably useful features, like lookaround assertions, conditionals, case
+;; modifiers or backreferences, among others. No, I want PCRE. I am going to
+;; have my cake and eat it too, damn it!
+;;
+;; Workflow:
+;;   + Invoke `=regex' (if opened with C-u, opens in separate workspace with a
+;;     dummy text buffer).
+;;   + A regex window will popup up. Any matches will be highlighted in the
+;;     original buffer.
+;;   + C-c C-k to close it
+;;   + TODO C-c C-e to export to various langauges
