 # @DESCRIPTION:
 # Same as enewgroup, you are not required to understand how to properly add
 # a user to the system.  The only required parameter is the username.
 # Default uid is (pass -1 for this) next available, default shell is
 # /bin/false, default homedir is /dev/null, and there are no default groups.
+#
+# If -M is passed, enewuser does not create the home directory if it does not
+# exist.
