+SYNOPSIS
+========
+
+   int logon(void)
+
+
+DESCRIPTION
+===========
+
+   When the parser accepts a new connection, it first calls
+   connect() in the master object and then applies logon() to
+   the object that is returned by the master. That will usually be
+   a special login object, that is expected to clone and get going
+   a user shell or player object.
+   Should return 0 on failure, everything else means success.
