 * If a dir under apps/ doesn't contain an app.rc file, werc fails to start. A possible fix would be to replace $werc_apps default with `apps/*/app.rc` instead of `apps/*/`, this would be backwards incompatible, but I doubt anyone uses that option.
 * Links in Blagh feeds become confused if markdown 'references' are used, markdown references suck, but I guess we need to address this somehow... 
 * Somewhat similarly to the abouve, relative urls in imgs, links, etc. can easily break when used in Blagh posts, so it is not all markdown's fault.

 The permissions system is very flexible, for example to only allow access to members of the group 'editors' you can do something like:
 
-    if(! check_user editors)
-        perm_redirect /_users/login
+    switch ($req_path) {
+    case /_users/login
+    case /pub/*
+    case /robots.txt
+    case *
+        if(! check_user editors)
+                perm_redirect /_users/login
+    }
+
 
 To automatically redirect users without permission to the login page if they are not members of the group 'editors'.
