+The
+.Nm
+utility refuses to remove users whose UID is 0 (typically root), since
certain actions (namely, killing all the user's processes, and perhaps

+.It Fl f Ar file
+The
+.Nm
+utility will get a list of users to be removed from

+which will contain one user per line.
+Anything following a hash mark
+.Pq Ql # ,
