+    # Version requirement:
+    #   This feature requires zsh 4.3.3 or newer.
+    #   If you use this feature and need to know whether it is active in your
+    #   current shell, there are several ways to do that. Here are two simple
+    #   ways:
+    #
+    #   a) If knowing if the profiles feature is active when zsh starts is
+    #      good enough for you, you can put the following snippet into your
+    #      .zshrc.local:
+    #
+    #   (( ${+functions[chpwd_profiles]} )) && print "directory profiles active"
+    #
+    #   b) If that is not good enough, and you would prefer to be notified
+    #      whenever a profile changes, you can solve that by making sure you
+    #      start *every* profile function you create like this:
+    #
+    #   function chpwd_profile_myprofilename() {
+    #       [[ ${profile} == ${CHPWD_PROFILE} ]] && return 1
+    #       print "chpwd(): Switching to profile: $profile"
+    #     ...
+    #   }
+    #
+    #      That makes sure you only get notified if a profile is *changed*,
+    #      not everytime you change directory, which would probably piss
+    #      you off fairly quickly. :-)
+    #
     # There you go. Now have fun with that.
