+userrc
+======
+
+A very simple script that executes ~/.config/rc.local for your users.
+
+    > ./userrc -h
+    Usage: userrc [-c config] [-l logdir]
+
+The script has two access modes: blacklist (default) and explicit.
+In blacklist mode, it will find and execute rc.local for every user in the system except for the ones in the `users_deny` array.  
+In expicit mode, it will find and execute rc.local for every user in the `users_allow` array.
