+* Q-LINE MODULE: Provides the /QLINE and /UNQLINE commands, allowing O-lined users with the server-ban:gline privs to manually add Q-lines (global nick bans) 
+* at the server level, rather than relying on Services to do so via the /(UN)SQLINE server-only command or config file access.
+*
+* USAGE:
+* 
+* Add a new Q-line entry: /QLINE <nickmask> :<Reason>
+* Delete an active Q-line entry: /UNQLINE <nickmask>
